DIY bath mixer tap repair

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

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 the simplest, 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 stuffing box. 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 scroll the deformed area a little with a mill. After this scrolling, the mixer is reassembled, 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 for mixing 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, turn out the branch pipe, 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, hold this part 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 need to immediately screw the branch pipe into its 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, often malfunctions 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:

In some cases, problems with faucets are the wrong sink or the wrong model. Most of the troubles can be solved on their own, but if difficulties arise, it is better to call a plumber - professional advice or repairs have not prevented anyone yet.

The faucet is an integral part of every bathroom, which has a hot and cold water supply. Thanks to him, the temperature of the water leaving the tap and its pressure are regulated. In addition, the faucet has a switch that allows you to redirect water from the tap to the shower. Like any mechanical device, the mixer is not immune to all kinds of breakdowns. Fortunately, its design is not overly complex, allowing, in most cases, to fix problems on their own.In the article, we will consider the device of a bathroom faucet with a shower, repair the faucet in the event of any breakdowns, and list the causes of malfunctions.

Consider how a bathroom faucet with a shower works. This will help you understand how it works, depending on the design. All faucets that can be used in the bathroom fall into 3 categories:

1. Sensory... The control element of such a device is a photocell that gives a command to turn the device on and off. Self-repair of such devices is very difficult, so it would be most rational to refer it to specialists.

2. Valve... The device of a bath mixer with a valve-type shower is quite simple:

frame;
spout;
valves. Designed for manual control of the mixer;
crane axle boxes. They regulate the water supply. Older models are fitted with rubber gaskets, while newer models have ceramic plates.

In the photo, the design of a valve mixer with a flag switch

Tip: Ceramic crane axle boxes are much more durable than older models, and they are much easier to operate, since the valve rotates a maximum of 180 degrees.

3. Lever... Recently, this type of mixer is gaining popularity. A typical lever model consists of the following elements:

frame;
spout (gander);
ceramic or ball cartridge in which water is mixed. Ceramic cartridges cannot be disassembled. If such a cartridge has become unusable, repairing a bathroom faucet with a shower will consist in replacing such a cartridge;
a control handle that regulates the water pressure and its temperature. Mounts on the cartridge arm;
nut fixing the cartridge in the body;
a housing cover that covers the cartridge and is designed to give the mixer a more aesthetic appearance.

The main components of the lever mixer with a cartridge

If you carefully study the device of a bathroom faucet with a shower, its repair will not be difficult. It is only important to know the reasons accompanying breakdowns:

Unsatisfactory product quality. This is typical for the products of little-known manufacturers who use low-quality components and consumables in their work;
Using consumables of the old design. For example, paronite or silicone gaskets last much longer than rubber products. In addition, they are less deformed and do not collapse from drying out;
Dirty water in pipes;
Increased water hardness affects the internal parts of the device, causing deposits and cracking of the seals.

Let us examine in more detail what breakdowns can occur during the operation of the mixer with a shower, as well as how to fix the mixer in the bathroom yourself. Malfunctions can be of the following nature:

This is the most common breakdown, as the gander constantly rotates in different directions, which leads to wear of the round rubber gasket... This gasket is located in the groove of the gander, therefore, to replace it, the gander must be disconnected.

Actions are performed in the following sequence:

the fastening nut is unscrewed;
the gander is removed;
the remnants of the old gasket are removed from the groove of the gander;
a new gasket is installed;
the gander is installed in place;
the thread onto which the fixing nut will be screwed is wrapped with 2-3 layers of FUM tape;
the nut for fastening the gander is tightened.

This failure is typical for single-lever mixers and is caused by cartridge breakage. It is necessary to disassemble the mixer, and replace cartridge... In addition to this failure, there are several other signs of cartridge breakage:

the lever has become difficult to control;
the temperature of the supplied water changes spontaneously;
there is no supply of either hot or cold water;
the valve does not close completely or does not open completely.

In this case, you need to replace the cartridge. Do-it-yourself bathroom faucet repair is performed in the following order:

The red and blue plug is removed from the mixer body.

Removing the crane lever

Use a small-tip Phillips screwdriver to loosen or loosen the retaining screw.

The lever is removed and the decorative cover is unscrewed.

Using an adjustable wrench, unscrew the nut that holds the cartridge inside the body.

The old cartridge is removed.

A new cartridge is inserted into the housing, after which the mixer is assembled.

Self-replacement of the cartridge on the mixer

Important: There are tabs on the cartridge body that should line up with the indentations inside the cartridge body. Match them carefully. If they don't match, the mixer will leak.

The reason for the leakage of the two-valve mixer is the wear or destruction of the sealing washer located on the valve box. The destruction of the crane axle box itself may also occur. If the faucet is leaking in the bathroom - how to fix it quickly and inexpensively? Only on my own replacing the crane-axle box or washer on it... There is nothing complicated about it.

All work is carried out with the water supply shut off:

the plug is removed from the leaking valve;
the screw with which the valve is attached to the mixer body is unscrewed;
using an open-end wrench or an adjustable wrench, the crane-axle box is unscrewed;
the crane box itself or the sealing ring on it is replaced;
a new or repaired crane box is installed in the old place.

There is another gasket between the faucet-shower switch and the body, which could be damaged. How to fix a bathroom faucet that has a leaking switch? Only by disassembling the switch itself:

the button (switch) is removed, for which the rod is held in a fixed position with pliers;

the valve with the stem is removed;

the damaged oil seal is removed;

in his place a new oil seal is installed;

the switch is put together.

Repair of a mixer with a flag switch is shown in the video.

If the button does not come back after being turned off, then its spring is faulty. Disassemble the switch as described above and then remove the broken spring. In her place a new spring is installed.

Replacing the Push Button Switch Spring

If the switch does not work, and water flows from the shower and from the tap at the same time, then the reason is cracked oil seal located on the switch stem... Necessary:

remove the button (switch);
remove the stem;
replace the oil seal;
assemble the switch.

This problem occurs due to damage to the hose gasket. If the bath faucet is leaking, do-it-yourself repairs will consist in replacing this gasket. To do this, simply unscrew the hose nut by hand, and then remove the worn out washer. In her place a new paronite washer is installed... Before tightening the nut, it is advisable to wind a couple of layers of FUM tape on the thread.

Nowadays, a hygienic shower for a toilet with a mixer is beginning to gain more and more popularity. More about it in our separate article.

Do you know how to remove limescale from the toilet? The problem is quite common, and there are several ways to solve it.

In-line water filters help extend the life of your plumbing. We talked about their types here.

How to fix a bathroom faucet if there is a water leak at the connection between the hose and the shower head? Very simple. There is a round insulating gasket under the nut on the hose. It can be easily replaced even without the use of tools.

If the water pressure through the mixer has noticeably weakened, but the neighbors have remained the same, you should suspect, first of all, clogging of the filter-aeratorlocated at the tip of the gander. Unscrew it by hand or pliers, and then check the pressure.If the pressure increased without an aerator, then the reason lay in its pollution. You need to carefully rinse it under running water, and then screw it back into place.

Tip: Often it is not the aerator itself that gets dirty, but the cleaning filter located at the entrance to the room. Therefore, if cleaning the aerator did not work, then unscrew the filter and check the cleanliness of its mesh.We figured out how to fix a DIY bathroom faucet with shower. When using higher quality consumables, such problems will occur much less frequently.

The bathroom in our time is a complex complex of various devices, plumbing connections and assemblies. As for the mixers, there can be two or three - it all depends on how many and what is installed in the bathroom. Any technique tends to break sometimes, and mixers are no exception, so you need to know what to do in these cases. With detailed information and an algorithm of actions, you can easily eliminate minor faults with your own hands.

Every modern bathroom is sure to have a mixer. Replacing the bath with an invigorating shower significantly saves water consumption. Sometimes the mixer breaks down, then repair or purchase of new units is required.

The faucet is one of the main devices in the bathroom, it is also in the bathroom, and in the shower cubicle, and in the sink, if it is installed separately. With the help of this unit, you can regulate both the water pressure and its temperature.

Mixers are of the following types:

The first one includes two valves, which, with the help of rotation, allow you to achieve the desired water flow and temperature. Such a unit is arranged simply, if necessary, it can be easily disassembled and repaired. When working, it is important to follow the recommended sequence of operations, this is the best guarantee that there are no unnecessary parts left after assembly.

Water regulation by means of the second type consists in the fact that the lever is lifted upward and pivoted to the side. Inside this structure, there is a large ball, which has special slots and is in contact with the lever.

Water at different temperatures enters through such slots and mixes. The water pressure is regulated by changing the angle of rotation of the lever.

The model with a ceramic cartridge has two plates that are in contact with each other. The plates move relative to each other when the arm changes position. This allows cold and hot water to mix.

The axle-box crane is reliably protected by seals, which can be:

Valve head assemblies can be changed. The axle crane, in turn, may consist of:

The tee connects several pipes, the second type is connected using a special wiring.

The lever mixer is very popular, its main advantages are:

ease of use;
reliability;
looks aesthetically pleasing;
ease of installation.

The device diagram of such structures is simple; unfortunately, it is not possible to repair them; the case is designed in such a way that it cannot be disassembled.

Tap-to-shower switches can be of the following types:

cork;
push-button devices;
cartridge type.
spool valves.

The most common and simple ones are cartridge-type switches. Their main breakdown is the wear of the rubber ring between the housing and the shift lever. The rubber of the gasket is located in an environment in which there is both high humidity and mechanical stress. Destruction of the gasket is only a matter of time. It is not difficult to eliminate the malfunction, for this you need to disassemble the device and replace the gasket.

What needs to be done to repair the crane:

shut off the water supply;
disconnect the lever from the mixer;
unscrew the screw from the switch;
dismantle the switch;
install a new ring;
wind the FUM tape on the thread in several layers;
put the lever in place, tighten the screw.

A common occurrence in spool switches is that the nut breaks, it fixes the switch in the shower itself. Similar incidents happen when the materials from which the mixer is made are made of cheap silumin material.

It is recommended to buy nuts and hardware made from hard alloys:

Such a malfunction is eliminated as follows:

the mixer is disassembled;
the hose is unscrewed from the shower;
the lower nut is unscrewed.

If the nut is out of order due to thread wear, then it should be replaced with an analogue made of a higher quality material. After processing with sandpaper, the device is assembled, lubricated with grease and put in place.

Often, breakdowns occur at switching points for other reasons:

failure of the button;
the passage of water simultaneously into the faucet and shower hose;
failure of the mechanism that controls the flow of water;
abrasion of the gaskets in the push-button switch itself.

The leak can be eliminated by changing the rubber rings. The pushbutton switch breaks due to the failure of the metal spring, which must be replaced.

If there is a decrease in the water pressure in two-valve type taps, then it is quite possible that a clogged aerator is to blame, it should be cleaned. It is also possible for the spools to fail, which are responsible for the flow of water entering the tap and shower.

Such units from bona fide manufacturers are designed for a long service life, so it is recommended to buy plumbing fixtures from reputable trading platforms. Each unit of the product must always be accompanied by genuine quality certificates and warranty obligations.

In order to repair breakdowns, you should use the services of masters with practical experience. In this case, it is good to have certain ideas about how the mixers are arranged, and what types they are.

Any mixer consists of several units:

frame;
rubber gaskets;
crane box;
decorative elements;
valves;
spool;
adapter;
crank.

The most common malfunctions are in the form of a leak, they are:

under the gander;
under the mixer lever;
under the mixer valve with two valves;
at the connection points of the hose and shower.
under the fastening nut, water may leak due to the wear of the gasket.

In this case, the repair can be done by hand; the qualifications of a plumber is not required here.

Often, faults can be easily eliminated by replacing a worn ring with a new one made of partonite. When winding the gander, it is imperative to lay the FUM tape so that the gaps are better sealed. Leakage in a lever mixer occurs when the cartridge itself breaks. Such a malfunction can be eliminated by replacing the cartridge. It can be of different sizes, it depends on the manufacturer. When buying a new cartridge, it is advisable to take with you the broken one, their compliance should be 100%.

Leakage from under the lever is eliminated in this way:

first, the cap is removed, which is marked with a red-blue marker on the handle;
the fastening bolt is unscrewed;
the lever is removed;
the cartridge is changing;
the mixer is reassembled.

It is always useful to know how to repair a bathroom faucet with a shower, do it yourself without resorting to the services of specialists. After all, sooner or later, any tap in the bathroom stops working properly. The main causes of problems are: wear of cartridges, gaskets, oil seals and fasteners. With simple instructions, everyone can figure out how to repair a bathtub shower faucet on their own.

In order to repair a bathroom faucet with a shower, it is not at all necessary to call a plumber. Any crane can be easily disassembled into parts.If a person understands his device, then the repair of a bath mixer with a shower will be quick and effective.

To find out how to fix a mixer, you need to figure out which parts of a particular design are responsible for malfunctions.

There are three main categories of bathroom faucets with shower:

Valve. This type has been known for many decades. The design consists of a gander and two valves. In older models of two-valve worm gear mixers, rubber gaskets are installed, the deformation of which leads to leaks. The new models are equipped with a crane-axle mechanism with ceramic discs. Holes are drilled in their center. When the valve is turned, the holes match - this is how water enters the spout.

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 bath mixer tap repair

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 the 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.
