DIY thermostatic mixer repair

The installation of a mixer with a thermostat in a bathroom should be carried out according to its intended purpose, i.e. it is not recommended to install this device, for example, in a shower or kitchen. This will affect the main function of the mixer itself. To install a mixer with a thermostat in the bathroom, no special efforts are required.

How to connect a mixer with a thermostat and, if necessary, repair it - you will learn from our article.

Manufacturers of the latest water heater taps and heated mixers always consider the possibility of installing them by non-specialists. Therefore, the installation of most of the models is not particularly difficult.

Regardless of the design features of a particular device, any model is installed according to one of the standard installation instructions.

Wall mounted thermostatic mixer

There are three ways to install a mixer with a thermostat:

1) Fixing to the wall.

2) Installation in a bathroom body.

3) Mounting a special shelf or a separate rack.

Mounting the thermostatic mixer on the wall is an economical and quite convenient way. The installation of just one design ensures the possibility of using a bath, a shower, and a sink.

Mounting the thermostat on the bathroom wall

When choosing the location of the device, it is necessary to take into account its design parameters. So, the drain spout should reach both the bathroom and the washbasin at the required distance so that water does not drip onto the floor.

This scheme has several important nuances that must be taken into account:

1. Location of water pipes routing.
2. The presence of a one-piece supply of pipes in the room.

In the last two decades, the projects of apartment buildings have provided for the installation of separate pipes for bathtubs and sinks. Therefore, this installation option is used less and less often. However, the connection rules provide for the installation of a mixer with a thermostat on the branch pipes - branches from the main pipes or mounting on the wall.

Mixers that heat water as it is fed to the spout are now becoming more and more popular. How do they work and what is their principle of operation? Read about this in the article on our website "How a mixer with a thermostat works"

If you have to make a do-it-yourself pipe supply for a mixer with a thermostat, then you need to be guided by the relevant standards. According to them, the height of the mixer in the bathroom with a thermostat should be 1, 2 m from the floor level. And only at the same level can water sockets be made, while the distance between them should be 15 cm.

1. Shut off the supply of cold and hot water, while it should not seep out, even with drops.

2. If there is rust and dirt on the stopcocks, then their joint is abundantly lubricated with machine oil.

3. Dismantle the old crane. But how to disassemble a mixer with a thermostat? This is pretty easy to do. For this:

Dismantling the old mixer with thermostat

6. The operation of all functions is sequentially checked.

The decision to install a thermostatic mixer in this way has several advantages:

1. The ability to completely mask all the details of the liner in the space under the sink or behind the bathtub.
2. The presence of more free space when arranging a bathroom.
3. The location of the pipes does not need to be taken into account, since the connection is made with flexible hoses.

Installation of a mixer with a thermostat above the bath

Most of the manufacturing baths today already have holes for mounting such a mixer. However, if your bathtub does not have these holes, it is quite easy to cut them.

The rules for connecting a mixer with a thermostat to the bathroom body do not differ from the instructions described above:

1. All old parts are carefully removed.
2. Clean and treat rusty surfaces.
3. Carefully install a new tap.

This is a rather expensive and complicated method. Its only advantage is the uniqueness of the design, which is suitable for exclusive bathroom interiors.

For standard apartments, in which the size of the bathrooms leaves much to be desired, such an installation is not suitable. In addition, the price of this mixer model is many times higher than other taps. And the last is the laboriousness and complexity of the connection, it leaves little chance of doing the work with your own hands.

So, having chosen a mixer with a thermostat to your liking, you shouldn't have a question about how to connect a mixer with a thermostat in the bathroom, if you carefully read the instructions for it and follow our advice in everything.

Today, it is quite possible to repair the thermostat with your own hands. We will give you some tips and tricks in this regard:

1. Cold and hot water must be shut off.
2. Residual water from the tap must be drained.
3. Before starting repairs, the sink must be covered with a cloth so as not to accidentally damage it.

Next, proceed to disassemble the thermostatic mixer. How to disassemble a mixer with a thermostat, see above.

In general, if the quality of the water and faucet with a thermostat is good, the likelihood of repair is significantly reduced and delayed in time.

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.

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.

A person's striving for perfection will never dry out, because it is largely thanks to him that new, more comfortable systems appear. It seems that until recently, people were happy with the appearance of a standard mixer, and now automatic temperature and pressure control is becoming the norm. Now we will look at how the mixer with a thermostat works and how it is better than its predecessors.

Photo of a mixer with a thermostat for a bathroom.

In dry language of definitions, a thermostatic mixer is a programmable device designed for automatic mixing of hot and cold water, as well as, in some cases, stabilization and maintenance of pressure when water is supplied to the consumer.

The principle of operation of a mixer with a thermostat, in general, is simple. It is based on the property of some materials, expand or contract under the influence of temperature. Specifically in these devices, a special cartridge is used, in which wax is laid or bimetallic plates are installed, which quickly change shape under the influence of temperature.

Such a cartridge, being the heart of the structure, is connected to a mixing, control valve, which directly controls the flow of hot and cold water. The adjustment of such a unit is carried out by means of a special adjusting screw that limits the range of valve travel.

This principle of operation of a mixer with a thermostat practically excludes sudden temperature fluctuations in the tap. A limiter must be installed on the adjusting screw, which will not allow the temperature to rise above the critical one.

Even if the cold water supply suddenly stops, the valve will simply shut off the hot water supply. Therefore, it will not allow boiling water to flow from the tap.

Mechanical thermostat operation.

Initially, it should be noted that the range of these units is quite wide. The devices are available for installation in the kitchen, bathroom, sink, as well as for shower and bidet.

But if a kitchen faucet with a thermostat can theoretically be installed on any sink, since it differs from a faucet on a bathroom sink only in appearance, then units designed directly for shower cabins, bidets or jacuzzis are unique, highly specialized devices.

• Perhaps the main advantage of such equipment, due to which it was originally developed in Europe, is the obvious economic effect. Installing a mixer with a thermostat allows you to clearly set the temperature, thereby controlling the flow of hot water. This is especially true for systems that use electric heaters.
• The next significant plus relates already to the area of ​​comfort and safety. With such a unit, you are not threatened with a sudden burn of boiling water in the event of an unexpected shutdown of cold water. Likewise, you should not be afraid of an ice shower if the hot water is turned off.

• If your mixer has a jet pressure control sensor, then you automatically cease to depend on pressure drops in the network. Residents of apartment buildings are well aware of this problem. When you take a shower, and the neighbors want to wash the dishes, you immediately feel this desire on yourself.
• Owners of autonomous electric heaters, boilers, know that such tanks heat water up to 90 ° C, naturally, such a temperature carries a potential danger. Installing a mixer with a thermostat completely eliminates any risk.
• If you are able to install a standard tap on your own, then installing a mixer with a thermostat with your own hands will not cause you any difficulties.

Important: such mixers have proven themselves well in families with small children and in homes where there is a big difference between the pressure in the hot and cold lines.

All manufacturers unanimously claim that the main disadvantage of such plumbing is its high price, which is more than offset by a high level of comfort during operation. This is of course true, although another drawback emerges in the vastness of our great homeland.

Everyone knows that in the overwhelming majority of regions of Russia the quality of tap water leaves much to be desired. Therefore, in order for such equipment to work for a long time and properly, you will need to additionally install a filter system for it.

Otherwise, the thermostat can quickly become clogged and malfunction. And repairing a mixer with a thermostat with your own hands, especially an electronic one, is extremely unlikely.

In such devices, the water temperature and jet pressure can be controlled in two ways. Mixers with electronic and mechanical control are available.

Electronic systems are equipped with a liquid crystal display. Control can be both touch and by means of buttons. Such devices, as a rule, are part of a smart home system and provide a lot of various additional options.

In addition to the traditional programming of temperature and pressure, the screen can display the time, volume and quality of water, as well as automatic on and off programs.

The electronics are usually powered by batteries or a power adapter. In especially advanced devices, an infrared port can be built in, which makes it possible to enter parameters remotely. But as mentioned earlier, the repair of such electronic devices is still a problem, not every city has service centers.

Mechanical devices, in comparison with electronics, do not look so presentable, but they are many times simpler. And, as you know, the simpler the mechanism, the more reliable and naturally longer it will work. Everything is done here by hand, so this equipment is more suitable for Russian realities.

Advice: if there are small children in the house, then whichever thermostatic mixer you choose, make sure that it has a childproof function. This, as a rule, practically does not affect the cost, but the function is really useful.

• If you do not completely trust the domestic manufacturer and are an adherent of foreign technology, then you should pay attention to one important detail. The instructions for such a mixer should contain information that this product is designed and manufactured specifically for the Russian market. This means that the manufacturers have adapted the equipment to our realities.
• The side of the location of the hot and cold lines is also of great importance.... If in a conventional mixer it is enough to change the red and blue chips, then in the case of a thermostat, the unit simply will not work or even break down.
• If the plumbing system in your home includes a connection between hot and cold lines... In other words, periodically hot water can flow from a cold tap, and vice versa, you need a mixer with a check valve. It will prevent hot water from entering the cold line.
• As already mentioned, almost all such devices are very sensitive to water quality, so it is better to buy a filter system right away.... After all, it is much easier to replace the filter once every six months than to throw out an expensive mixer after a year.

Summing up all of the above, I would like to note that if it is quite possible to install a mechanical thermostatic mixer with your own hands, then it is better to entrust the electronics to specialists.

There is a Mora mixer in the shower.
After 4 years of work, the pressure became very weak.
Moreover, in the washbasin, which comes after the shower, the pressure is wonderful.
Is it being treated or in the morgue?
Who has experience?

Between the eccentric and the union nut, there are most likely protective nets - they can be removed and washed

.
If it is not in the meshes, then it is possible inside the calcium deposits. In theory, they can be washed with a hot descaling solution. by connecting a fontanel pump to the mixer inlet and opening the spout to drive the solution (from the bucket through the mixer and back into the bucket). Boiler heat exchangers are flushed this way. I didn’t see the mixer rinsing ... Although I came across a case when a dude put the whole mixer in a bucket with decalcifier. He speaks normally, but he turned black all over .

By the way, maybe it's not the mixer? And in a watering can or a hose? Personally, after replacing the mixer with a new head, it almost did not change, but replacing the hose and watering can became an order of magnitude better

I took your advice, I also have Oras worth it.

The only small question arose, on point 4, namely on the moment

Are you just cleaning it on the outside? Or can it be disassembled and cleaned from the inside?

Why am I asking, I washed it outside, even rubbed it with a toothbrush, not much, it seems to me cleaner.

Installing plumbing fixtures in the bathroom is a real art. Proper location and professional installation are important. The quality of products and technical characteristics play an important role. For example, the mixer device must assume the possibility of repairing or replacing structural elements.
