Do-it-yourself oras mixer repair

In detail: do-it-yourself repair of the oras mixer from a real master for the site my.housecope.com.

At first glance, a thermostat is a complex and sensitive device that cannot be cleaned without being a 6th grade plumber.

Naturally, this is not the case. We decided to photograph and describe the process of disassembling and cleaning the thermostat, which had been in operation for about 9 months. Due to the construction of new housing, the water was often cut off, after which something yellow flowed from the tap for a long time. And although the thermostat itself worked fine, there could be no dirt inside.

Horizontal mud collectors are standing, that's good:

0. Before work, the water must be shut off!

1. First remove the thermostat knob.

Remove the small end cap, unscrew the screw, and remove the handle and retaining ring. Our thermostat comes with a key:

We use it to unscrew the screw that secures the thermostatic unit from below.

The screw is very small, it is important not to lose it.

2. We take out the block.

Light effort may be required.

3. We clean off plaque with an old toothbrush.

Plain water, no soaking.

4. Carefully insert the block back and screw in the screw.

The hole in the housing must line up with the threaded screw hole. It is advisable to lubricate the rubber rings with plumbing petroleum jelly or a similar grease.

We removed the thermostat from the wall before work, but this is not necessary, it’s just more convenient to take pictures.

5. Align the labels.

Now you need to put the handle so that the water temperature corresponds to the set one.

Each thermostatic unit has factory calibration marks. We combine the mark on the stem with the mark on the body by turning the notched stem. This position corresponds to approximately 38 ° C.

Video (click to play).

6. Put on the retaining ring so that the mark on the ring is visible when using the thermostat.

7. Put on the handle.

The stop inside the handle (when the button is not pressed) must be close to the stop on the ring. This position of the handle corresponds to 38 ° C.

8. Tighten the screw securing the handle and insert the plug.

If in doubt, refer to the thermostat assembly diagram:

Now it is clear that the 6th category is not needed here, the actions are quite simple. Even if you yourself do not dare to clean, you can control the actions of the plumber.

By purchasing Varion thermostatic mixers you get a real 5-year warranty, information support and provision of spare parts for mixers for the entire service life.

If the faucet is leaking, it is not necessary to call a plumber and pay for his work. In our article, we will figure out how to disassemble a single-lever mixer and do it yourself repairs. To carry out the work, it is necessary to familiarize yourself with the device of this sanitary-technical device and prepare the necessary tool.

Experts associate the appearance of water from under the lever of the mixer with a breakdown of the cartridge. In this regard, we will need to disassemble the device and replace the cartridge.

At the initial stage of work, you need to remove a small rounded decorative cover. Typically, this plate has two colored dots (red and blue) indicating that the tap lever is turned to add hot or cold water. If the direction of fluid supply does not match, the lid is turned over to the opposite side.

Single lever mixer device

When the decorative cover is removed, a screw is exposed inside the hole that holds the lever in working position. This lock can be removed using a standard or Phillips screwdriver. There are times when a hexagon is required to remove the tap.

After removing the lever in one way or another, remove the decorative cover.It so happens that this detail also cannot be removed in the usual way. The insert can be loosened by hand; to improve the effect, place a soft dry cloth at the place of application of force. If the cap could not be removed by hand, then to pull it out, you can use:

To protect the surface, the working part of the tool must be in contact with the part through the fabric. After several rotations in different directions, you can quickly remove the decorative cup.

After removing the protective cover, we see the cartridge in front of us. Now you need to unscrew the ring nut and you can remove the mechanism for supplying and mixing water. After pulling out this part, on the bottom you can see the landing grooves, which are used to install the device in the working position.

Cartridge slots

If, after removing the cartridge, wear and tear from metal corrosion was noticed, then the mixer can be replaced with a new one. In some cases, water leakage from under the lever is eliminated by tightening the nut.

Mixer assembly begins with the installation of a new cartridge. After that, we tighten the circular nut, install the decorative cup. Next, we install a lever or a flag and fix its position with a screw. If the fasteners were rusty or had damaged threads, then the lever must be firmly fitted onto the cartridge holder.

The main reason for this fairly common phenomenon is considered to be metal corrosion in the seat. We have already said that you can try to cover such areas with silicone, but if this does not help, then you will need to change the entire mixer.

Spontaneous lowering of the mixer lever usually tells us about its breakdown. When you click on the checkbox, water can be supplied in a thin stream or not at all. Many believe that the main cause of this lever behavior is cartridge failure, but this is not always the case.

All residents of a city apartment or a country house use plumbing differently. Some open the taps carefully, others, for example, children, jerk the flag sharply. In the latter case, damage to the inner part of the lever, which is put on the head of the cartridge, may be damaged. In case of damage, the walls of the square insert diverge to the sides, which leads to a certain amount of free movement of the part; when it is lifted up, the crane begins to fall.

In some cases, water may leak from under the faucet jacket. The main reason for this phenomenon is considered to be damage to the gaskets, and the liquid can leak both in the upper and lower parts in the area where the circular nut is located.

Water from under the gander's shirt

In this regard, during the installation of the single-lever mixer, the circular nut must be tightly tightened. This part is often unscrewed or loosened during transport of the product, resulting in a small gap. This gap is quite enough for water leakage.

If the nut is tightened well, then the cause of the leak will be a faulty gasket.. To eliminate the problem, unscrew the nut, remove the nylon washer (serves to form a working gap between adjacent rotating body parts). Next, we remove the mixer spout along with the jacket and carefully check the installation locations of the gaskets.

There should be no traces of corrosion, sinks, etc. The only solution to the problem in this case is to replace the gander from the old tap; in the worst case, you will have to replace the mixer completely.

The second reason for water leakage from the jacket is the wear of the gaskets.... Such parts are made in the form of a horseshoe, and their working, most of them are facing the water chamber. It is quite difficult to buy a new gasket for a tap, but it is possible to repair a faucet.

Disassembling the mixer to eliminate leakage from under the shirt

For this, several layers of fum-tape are laid in the seats, which will increase the diameter of the seals and improve their tightness. Next, put on gaskets, install nylon washers, assemble the rest of the mixer.

Before installing the valve in a permanent place, check its tightness. If the repair work is done correctly, water does not flow, then the mixer can be fixed to the sink.

Single-lever mixers attract with their laconic design and easy control of the water flow. Turning on the water, changing its temperature and pressure - all this with one turn of the knob. These devices are reliable, have a solid service life - some branded ones give a 5-year warranty. Nevertheless, repairs to the single-lever mixer are periodically necessary.Despite the external similarity, there are two types of rotary or single-lever mixers - with a cartridge (cartridge) and ball - with a ball inside. You can repair any of them, but for this you need to disassemble them first. And so that you can not only disassemble, but also assemble, it is advisable to get acquainted with the internal structure of each. Image - DIY repair of the oras mixer

The design can be different, the structure remains the same

Cartridge mixers are so named because their locking and regulating mechanism is hidden in a special cartridge flask. In the more expensive models of faucets, the cartridge body is made of ceramic, in the cheaper ones it is made of plastic. What are good about these models is the ease of repair, but with them it is not always easy to achieve the required pressure - you need a tighter control of the handle. But it is very easy to change the temperature of the water - with a slight movement of the hand.

The structure of a single-lever valve with a cartridge is simple. If you go from top to bottom:

Switch with fixing screw.
Locking (compression) nut.
Cartridge. It mixes the streams of water, the same device shuts off the water.
The body of the mixer, which has a seat for the cartridge.
Fasteners, studs and gaskets to ensure tightness.
Spout (gander). It can be a separate part - in swivel models for the kitchen or part of the body - for sinks in the bathroom.
If the spout is separate, gaskets are still installed from below and there is still a part of the body.

What a single-lever mixer cartridge consists of

The cartridge itself contains several (usually 4) specially shaped ceramic or metal discs. A stem is welded to the upper disc. By changing the position of the rod, we change the position of the plates relative to each other, changing the amount of water passing through the holes in the plates.

For the faucet / mixer to work properly, the plates are ground very tightly. For this reason, single-lever cartridge mixers are very demanding on water quality. The ingress of foreign fragments between the plates leads to the fact that the valve leaks or stops working altogether. To avoid this, some manufacturers install filters on the inlet pipes. But, it is better to put filters on the water supply and get clean water, which can be safely supplied to household appliances.

It got its name from the element in which water is mixed - a ball with cavities. The ball is usually metal, hollow inside. The outer part is polished to a high shine. There are three holes in the ball - two for the inlet of cold and hot water, one for the outlet of the already mixed one. A rod is attached to the ball, which goes into the cavity on the handle. This rod with a rigidly attached ball also changes the temperature of the water, its pressure.

The structure of a single-lever mixer with a ball-type water mixing mechanism

It is easier to adjust the parameters with such a device - the parts are well ground in, the handle moves easily. Ball mixers are less critical to the presence of mechanical impurities, but do not respond very well to the presence of hardness salts and excess iron. So for normal operation, pre-filtering is also required here.

Repairs to single lever cartridge faucets often involve overhauling and cleaning the O-rings. Salts are deposited on them, debris and dirt accumulate, which is why the tap starts to leak. To eliminate this nuisance, the mixer is disassembled, all parts are wiped from contamination (with warm soapy water), rinsed, dried, and put in place.

The sequence of installation of parts in a cartridge single-lever mixer

Let's figure out how to disassemble a faucet with a cartridge. First, turn off the water, and then the procedure is as follows:

Remove the decorative cover on the handle. Just pick it up with a screwdriver.
A fastening screw is hidden behind it. We unscrew it with a hex wrench and take it out.

First, unscrew the fixing screw

That's all. The single-lever mixer with cartridge was disassembled. As you can see, there are not very many details. The main working part is a cartridge. It is in him, inside, that mixing takes place.

The cartridge itself has a sealing gasket - a rubber seat at the bottom, which provides a snug fit to the body. Over time, rubber loses its elasticity, water begins to ooze. If this is the problem, you can first try to clean this ring of salts and deposits that have formed on it. Put the cleaned part in place, check the work. If the leak does not stop, the cartridge will have to be replaced.

One-hand mixer cartridges

Mixer cartridges have different diameters, inlets and outlets in the lower part are located in different ways. Therefore, if you need to replace it, first you disassemble the mixer, get the cherished part and go with it to the store or to the market. You need to choose exactly the same model without any deviations. At home, you install the cartridge into the case, turn it slightly until you feel that it has "sat down" in place. Next - the assembly, it goes in the reverse order.

Install the compression nut first. Actually, at this stage you can check how the new cartridge works. Turn on the water, adjust the temperature and pressure with the rod. To make it more convenient, you can put a handle on the stem. If everything is ok, continue with the build.

The single-lever ball mixer was invented a little over 40 years ago. Its design is simple and reliable - there is actually nothing to break. If problems arise, it is only because of poor-quality water - dirt particles settle on the rubber seats on which the ball rests. Contact deteriorates, water seeps out and the faucet starts to leak. Image - DIY repair of the oras mixer

How to disassemble a single lever ball mixer

Some ball valves are also available with a cartridge. Only the inside of the cartridge is not a plate, but a ball. Disassembly of this type is no different from that described above. The whole difference is hidden inside the flask. There are also other types of taps. In them, the shut-off ball is installed directly in the rubber seat. There are some minor differences here.

The tap lever is removed in the same way - first remove the plug, then unscrew the screw with a hexagon. Pull the lever up, remove it. After the actions are very simple and similar to those described above:

We unscrew the cap, preferably with our hands, since it is usually made of thin metal, it is easy to bend it.
We unscrew the clamping nut, there is a washer under it, we also remove it.
Access to the ball is now open. We pull the stem, take out the ball.
There are two saddles under the ball, with springs so that the rubber bands are pressed more tightly against the ball.

All dismantled. Next is the repair of a single-lever mixer. In theory, the problem is that deposits have accumulated at the point of contact between the ball and the seat. They must be removed - gently clean, wipe. There may be problems with the springs. They also sometimes accumulate dirt, but more often they simply lose their elasticity.

The third source of problems is the ball itself.Actually, it should be made of stainless steel, therefore, it only needs to be cleaned of deposits. In reality, this is not always the case - cheap taps have appeared, even with plastic balls or made of cheap metal. In this case, peeling of the surface or other similar troubles may occur. Such a locking element will no longer work normally. It needs to be replaced. With a ball, you also go to the store, pick up a replacement of a suitable size. Assembling the mixer in the reverse order: the springs from the saddle, the saddle is out of place, there is a ball on them, etc. Collecting the entire structure, carefully center everything - a skew will lead to rapid wear and the valve will flow again.

Faucets with a swivel spout are placed on sinks in the kitchen or on the bathroom. Periodically begins to flow from under it. The locking mechanism in this case is not to blame, it is just that the gaskets have lost their elasticity or the lubricant has dried out.

Repair of a single-lever mixer with a movable spout

In this case, disassemble the mixer as described above, then remove by pulling up the spout. Remove all old gaskets. If they are stuck, you can use a flat screwdriver or even a knife blade. You need to remove them, but they still need to be replaced. Select new ones from the removed gaskets. It is desirable that they be made of silicone, not rubber. Silicone is more elastic, retains its properties longer, and better tolerates contact with water.

Lubricate new gaskets with plumbing silicone grease, install in place. Replace the spout. It must be pressed down well so that it rests against the union nut on the mixer body. Next - the assembly of the rest of the mechanism.

Probably, every person has come across a situation when he found a puddle of unknown origin on the bathroom floor. An attentive person immediately found a small stream of water flowing down from the mixer.

That's it, you need to call the plumber ...

Or try to repair the mixer yourself.

With the mixer, which is in the kitchen, everything is more or less clear. This is the simplest type of mixer.

You can replace it in the following way.

We shut off the water using ball valves.
Using a screwdriver, remove the "lambs" from the mixer taps.
Using an open-end wrench, unscrew the taps from the mixer.
We change the gasket to a new one.
We screw the tap into place, having previously wound a sealing tape on the thread.

The last step will prevent leaks in the kitchen faucet through the threads.

It is more difficult to troubleshoot a bathroom faucet.

Let's try to understand this issue.

First of all, there are two types of faucets in the bathroom:

Each type of mixer has its own advantages, disadvantages, and, therefore, its own special defects.

Let's start with the breakdowns of single-lever mixers.

Mixer leakage.
Weak water jet.
Simultaneous flow of water into the drain and into the shower net.
Failure of the pushbutton switch.
Leak in the area of the push-button switch button.

Most often, the cause of this malfunction is a small speck that has ended up in the mixer mechanism. Sorinka can be caught between the ball and the ball sleeve or between the valve discs.

In this case, you need to replace the cartridge.

It is necessary to remove the decorative plug of the water switch lever.
Unscrew the retaining screw under the cover.
Remove the selector lever from the mixer body.
Replace cartridge.
Assemble the mixer.

The cause of this malfunction may be a clogged aerator.

Unscrew the aerator.

The aerator mesh must be blown out and rinsed from both sides.

Restore original position.

There may be several reasons for this malfunction, but the main one is most often the wear of the gaskets in the spool switch.This malfunction can only be eliminated by replacing the gaskets and rings.The only problem with such a repair is the rubber rings for the spool, which are rarely found on the free market.A spare kit is usually sold with the mixer. But, if it has not survived, then as a temporary measure, you can cut such rings yourself. Any dense rubber is suitable for this purpose. But such rings will not serve for a long time.The reason for this malfunction is a broken spring. This means that in order to eliminate this malfunction, it is enough to replace the spring. The diameter of the new spring needs to be adjusted to a slightly smaller size.The cause of the malfunction is a damaged oil seal. It just needs to be replaced. You can buy oil seals at any hardware store. The mixer instruction manual usually describes the standard procedure for this replacement.As you can see, repairing a bathroom faucet is not such a difficult operation. Even if the mixer is single-lever.This defect is eliminated by replacing the gasket.Broken shower-spout switch The switching mechanism is simple. If such a breakdown occurs, then when disassembling the mixer, you can immediately identify the broken element and replace it.There may be two reasons for this:

Wear of gaskets

Defective conical plug machining.

Both of these reasons can be eliminated by disassembling the mixer and replacing the damaged elements.Faucet repair will not take a thinking person a lot of time. You just need to turn on the logic, open the instructions and do a little work with your hands. It's not as difficult as it sounds.How to fix water leakage from the mixer, see the following video:

Bathroom faucets differ from others in the presence of a bath-shower switch, which are also divided into several types.

The part, the failure of which is characteristic precisely for the repair of the mixer in the bathroom, is the switch for the shower. He is responsible for switching the water supply to the mixer spout or watering can. There are 4 main varieties:

Suberic. An outdated version of the switch that few people produce today. It is characterized by a long handle between the two valves. Some modern bathroom faucets use similar handles, but they have a spool instead of a cork core.
Cartridge. It is preferred by Russian manufacturers. There are two types of cartridges on the market: ball and ceramic. The ball cartridge can be repaired, the ceramic cartridge can only be replaced. However, the latter lasts longer and is less susceptible to hard water.

Do-it-yourself mixer repair does not take much time if you correctly establish the cause of the malfunction. Any device ever fails.The mixer is no exception.

It can break down due to wear on the components. The lower the quality materials, the shorter the service life of the components and the more often the bathroom faucet has to be repaired. How to repair a faucet in a bathroom with your own hands?

Usually caused by a broken cartridge in a single lever mixer. The fact that the cartridge is out of order will also be indicated by the following signs:

the handle is difficult to rotate;
the water supply is not completely shut off;
the water temperature changes arbitrarily;
cold water flows from the hot tap and vice versa.

To replace the ceramic cartridge:

remove the blue-red painted plug;
use a Phillips screwdriver or hex wrench to unscrew the fixing screw;
pulling the handle up, disconnect it from the body, and then unscrew the lid;
with an adjustable wrench, unscrew the nut that secures the cartridge in the body;
replace the damaged cartridge.

After replacing the defective element, you need to align the protrusions on the cartridge housing with the grooves inside. If you overlook this, the faucet will leak.

In two-valve mixers, the sealing washer is often worn out. Sometimes the crane-axle box also becomes unusable. Such breakdowns lead to leakage. To replace the crane box or rubber ring:

remove the plug from the faulty valve;

unscrew the screw securing the valve to the mixer;

with an adjustable wrench, disconnect the crane-axle box;

replace the crane box or ring.

Before repairing the switch on a bathroom faucet, be sure to shut off the water in the room. A leak from under the switch indicates that the oil seal between the mixer being repaired and the switch has become inoperative. To replace it:

remove the button by clamping the stem with pliers;
remove the valve with the stem;
pull out the damaged oil seal.

If, after water procedures, the button cannot be returned to its original position, then its spring has broken. In this case, the switch is disassembled according to the algorithm described above, the faulty spring is taken out and a new one is put in its place.

Sometimes the shower switch does not work, and water flows into the shower head and mixer at the same time. This is due to a crack in the oil seal, which is located on the stem. To eliminate such a malfunction, you need:

remove the switch;
get the stock;
replace damaged oil seal.

Many apartments still use old plug switches. Over time, the button moves away from the housing, resulting in a leak. To eliminate it you need:

disconnect the screw;
remove the handle;
unscrew the nut;
remove the lock washer;
get the cork;
wipe the cork and the inside of the case with kerosene;
use abrasive paste, paraffin or petroleum jelly to rub the plug to the body.

The gasket in the spool switches may wear out. To replace it, you should:

disconnect the hose;
remove the spout;
unscrew the adapter;
unscrew the valve;
get the spool;
replace rubber rings.

The repaired button will last for several more years.

Over time, the gasket at the point where the hose is attached to the mixer will wear out. A leak is formed. Such a breakdown is the easiest to fix: you just need to unscrew the shower hose nut, remove the damaged washer and insert a new one in its place.To fix this malfunction in a mixer that has broken, it is also not necessary to use tools. You just need to unscrew the nut that secures the watering can to the hose and replace the insulating gasket.When troubleshooting bathroom faucets, repairs are not limited to replacing gaskets and cartridges. With prolonged use, the shower head holes become clogged with sand, limestone and other hard deposits.In order for the shower to work properly again, the mesh must be disassembled and rinsed. On some models, the screw is located under the plastic cap in the center of the watering can. Sometimes, in order to disassemble the mesh, it is necessary to turn it counterclockwise. Image - DIY repair of the oras mixer

An aerator is screwed onto the end of the spout.It retains solids and increases water pressure. If the water flows in a thin stream, the reason lies in the clogged filter. To clean it, unscrew it with pliers, carefully disassemble it into its component parts and rinse them under running water.

Specialists are faced with other types of breakdowns:

A continuous flow of water signals a breakdown of a brass valve or a clogged space between it and the gasket. The mixer must be restored if it is disassembled, the insides cleaned and, if necessary, replace the valve.
If no water flows when the valve is open, then the rubber gasket is dry. To make sure of this for sure, they hit the open tap with a hard object.

Do-it-yourself bathroom faucet repair does not require special skills. This craft can be mastered not only by men, but also by women. Regardless of the type of faucet in the bathroom, repairing and replacing parts is not difficult.

Faucet leakage problems are relevant to bathrooms, which we use several times a day. Small droplets dripping slowly and continuously from the mixer are the first signal that an urgent repair is needed.It is not difficult to eliminate the breakdown, having an understanding of the device mechanism of the device. As they say, repairing a mixer with your own hands is an everyday matter.Typical mixer problems are leaks caused by:

faulty shower;

defects of the conical plug;

wear of the crane axle box.

But most often the rubber gasket wears out, the condition of the crane depends on its integrity and strength.Most often, leakage from the valve is due to the wear of the rubber gasket in it. This is the most common situation. Both mixer taps can leak.You will need the tools shown in the photo:

The thickness of the new gasket is from 4 mm. You can make it from a piece of rubber sheet. The process of cutting it is simple, but if there are doubts about the quality of hand-made production, then in the future it is advisable to change the home-made gasket to a factory product.As a template for cutting the gasket, the one that needs to be replaced is suitable. If it is too deformed, then it should be taken into account that the manufactured part of the seal must be 1 mm larger in diameter than the previous one.The edge resulting from the increase in Ø should be reworked: cut along the circumference from the side of contact with the seat at an angle of 45º so that this seal “fits” tightly into the hole to be closed and the valve with a new gasket does not buzz.After replacing the gasket, everything must be returned to its place. Insert the crane-axle back. Usually, when removing the crane axle boxes, it is always advised to treat the internal cavity from plaque. This plaque is usually the result of the hardness of the water. A plumbing adjustable wrench is used in the reassembly of the mixer.In most cases, mixers have problems with valves, especially with half-turn ones. The valve can be changed or repaired. There are no particular difficulties in how to repair a broken mixer in the bathroom yourself.In a conventional valve, which is unscrewed in a circular motion, most often it is necessary to change the gasket or gland packing. A brief instruction on replacing the gasket is posted above, and in case of problems with the gland packing, they usually try to tighten the gland.Here, a small nut will be involved, located at the base of the crane box. The cross section of this nut is square. In a clockwise direction, you need to tighten the nut until it stops.If these manipulations turn out to be useless, then it will be necessary to unscrew the oil seal ring. After unscrewing, a special gland packing is wound around the valve stem. Then the ring will need to be screwed back well. All of the above actions help to stop the leak.Repair of the valve seat - the cavity into which the valve box is screwed in - is necessary if, after replacing the gasket or valve box, water does not stop flowing from the valve. With prolonged use of the mixer, it often deforms, and this causes leaks.Chips and scratches that appear can be removed by milling. It is necessary to slightly scroll the deformed area with a cutter. After this scrolling, the mixer is assembled, and if the seat is properly polished, there will be no leakage.To solve this problem, you need to do the following:

buy a switch;

disassemble the crane;

replace the broken part.

If deformations are found in the conical plug used to mix water from the hot and cold water supply pipes, it must be replaced. When eliminating any breakdown, the water supply is always shut off. The following photo shows how the switch is removed:When eliminating the above-described malfunctions, it is not necessary to remove the mixer from the mount. But there are also more global problems with valve mixer, which are also quite solvable.Learn more about some malfunctions of plug-change mixers and how to fix them.The shower-spout switch mechanism can be repaired without replacement. Consider the original way of fixing the switch flywheel to the stem:Now we just have to drill a hole on the switch stem and assemble the mixer:Eliminate the leak, following a specific algorithm, and then change the mixer.

Initially, in this situation, the water is turned off. Special shut-off taps are located on the water supply pipes.

After closing, for testing, the valves are turned to the opening side to the maximum.

Then the connecting nuts are very carefully unscrewed. They break easily in modern mixer designs. Regular brass nuts are easier to unscrew. They will not crack or break. A broken nut needs to look for an analogue in shape.

Next, remove the mixer.

When removing the mixer, the pipe is turned inside out, at the border of which a leak is detected with the coupling. When unscrewing, the edges of the branch pipe are held with a wrench or by the collar. A nut is screwed onto the removed branch pipe. You need to tighten it correctly, to the end. The new nut is taken from the old mixer. The reliability of the installation of the nut is determined in comparison with its original position.When it comes to replacing the mixer, be sure to determine the size of the nozzles. The mixer is always sold complete with them. When differences are found between the old and new nozzles, both are changed, and not only the one that flows. If they are identical, then only one can be changed.To understand how the leak is removed in this case, consider the diagram:During the installation of the branch pipe, there may be nuances. When screwing in, this part is held by the collar. The thread must remain free by two turns. All others are wound with sealing threads. Usually this seal is advised to be impregnated with linseed oil or oil paint. After such wetting, you must immediately screw the branch pipe into its proper place - this serves as a guarantee against repeated leakage.After cutting off the water, they first try to simply tighten the nut, and then, after supplying water, check for a leak. If the leak persists, the nut is unscrewed, and the mixer moves along the branch pipe closer to the wall. Then you need to remove the hose attached to the bracket.This is necessary to regulate the position of the mixer. Moving the mixer, they look at the end of the branch pipe, because it is with respect to it that the location of the device is changed.This is done until it becomes possible to remove the old gasket, which adjoins the nut and ensures tightness. You can try to remove the gasket without touching the mixer. This often fails. The reason for this is the adhesion of the gasket to the pipe (to its end).It is also not possible to pull out the pressed gasket. Then the shower is detached from the wall. This will help turn the mixer.All nuts on the mixer are loosened to facilitate turning.The replacement gasket is simply cut out of the rubberized sheets. In thickness, it should be from three to five millimeters. On the nut, you must prudently leave free space for two threads of thread. After replacing the gasket, everything easily falls into place.Sometimes there is a leak between the body and the sidewall. The mixer is separated from the piping, then from the shower. Remove the nose. The sidewall is turned inside out. Then it is smeared with putty. You can use paint instead of putty. Do not use the mixer until the lubricant is completely dry.Usually the problem is associated with blockages in the supply line to the mixer. The pipes and sidewalls can be clogged. To correct the situation, you will need to clear the blockage. For this, the valve head is turned out. Then a steel wire is pushed into the resulting hole. We take out all the garbage, sand. Then you can clean the cavity with a vinegar solution from plaque.A similar nuisance is a sharp decrease in the water pressure from the spout. Usually the cause of the problem lies in the blockage of the aerator. It is solved by unscrewing it and cleaning the meshes. They are purged and then washed. You can use a needle to remove sand from the mesh.

What if the water flows, but the spout falls? This is due to the fact that the retaining ring broke. There is a temporary solution before purchasing a new part.After closing the valves, you need to make an expanding ring. It is usually made from copper wire. The diameter of the material for the ring must match the diameter of the old product. After the ring is made with a soldering iron, it is advisable to treat it with liquid oil. This will prevent rust formation.This situation is associated with loss or breakage of the limiter. Knowing where exactly this part is located, it is easy to put it back in place. To do this, disassemble the mixer, find a malfunction and return the element to its place, applying light blows with a hammer to the protruding part of the limiter. Also, the stopper can be replaced with a small piece of brass wire - this will at least temporarily solve the problem of leaks.Sometimes there are troubles with a shower hose and a watering can, more often due to wear of individual elements or poor water quality.Typically, water does not pass through the mesh well when there are blockages in its holes. Here, after removing the mesh, it is easy to clean it with an ordinary awl or needle.After screwing the mesh back, the water supply and the direction of the jets are restored. Both the plastic panel with holes and the rest of the shower and mixer can be wiped with a vinegar solution to remove plaque and stains.If the leak appears due to wear of the inner part or the winding, it makes no sense to repair the hose, it is easier to buy a new one. Its cost is low, and the service life of new modifications is much longer.If both the drain and the shower are leaking at the same time, the point is in the loosened joint between the cork and the body. To remedy the situation, first unscrew the locking screw. The next step is to tighten the union nut. This reduces leakage, but it is difficult to switch the water from the drain to the shower.To completely eliminate the leak, you need to grind the plug to the mixer body using special lapping pasty compounds. They are sold in many stores.Lever joystick mixers are preferred by most people. It is very convenient to use them, since only the mixer handle is turned to achieve the required water temperature. It is also very easy to create the required water pressure by moving the lever up and down.To understand how to fix a single-lever mixer yourself, you need to have an idea of its device.Instead of valves with gaskets closing the channels with water, there are special cartridges here. They are usually ball or disc. They do not need to be changed as often as the same gaskets.The disc cartridge cannot be replaced with a ball cartridge. For a ball lever mixer, only their cartridges are suitable, and for a disc mixer - their own.Hinged, they are single-lever or joystick, mixers are extremely sensitive to the quality of tap water. Therefore, malfunctions often occur not due to breakdown or failure of the locking device, but due to the appearance of sediment and clogging of the mates of moving parts.Let's take a look at how the Grohe Eurosmart bathtub model 3300001 was cleaned with a spout 08915 that switches the shower to the spout. This device did not work; water was simultaneously flowing into the shower head and into the gander. Note that the master did not have to replace parts and seals, it was enough just to remove rust and calcium build-up.After cleaning and flushing the switching mechanism, it remains to "figure out" the pressure. As it turned out, for this it is enough to clean the spout aerator:After the traditional shut-off of the water, we unscrew the fixing of the mixer. Then you will need to remove the lever as carefully as possible, and this must be done carefully, slowly loosening it. Raise and pull the lever only when no resistance is felt. To continue working, you need to unscrew the thread connection.After dismantling the mixer dome, the plastic component will be visible. Behind it, a seal is usually visible, which needs to be cleaned or replaced. It is a regular rubber gasket. If the ball element is damaged, it must also be replaced.The ball is fixed with seals, the suitability of which must be monitored.Lever (joystick) faucets need careful handling, easy and smooth operation.When installing any cartridge, be sure that the projections on it are identical to the projections on the mixer.Disk cartridges rarely need to be replaced as they last up to 10 years. But mixers with such a consumption are not cheap, although they fully justify themselves.A little about how to postpone the repair of the mixer for a long time. One of the simplest solutions is to monitor the quality of the water supplied to the mixer using modern mechanical filters. The hard particles of sand and pebbles will not spoil the parts, and they will last much longer.It is recommended to install coarse filters at the beginning of the fork in the water supply system of the dwelling. Today a self-cleaning filter is available to the consumer. All filtered sediments from it are sent straight to the sewer. It is not always possible to install a large filter. Where it is not there, the mixer itself is connected to the connecting taps, where cleaning filters are already built in.Filters are available to reduce water hardness. This is important for ceramic faucets, as they suffer the most from the presence of salt deposits in the water.And finally, some advice from experienced plumbers. If the pipes hum when you turn on the mixer, you need to check how well they are fixed and, if necessary, fix them with clamps. In some cases, the humming is due to high pressure in the pipes, then a special reducer will be required to reduce the pressure. This noise is often caused by worn valve gaskets; after replacement, it disappears.Before the upcoming replacement of the gasket, it will be useful to watch the following video:
