Bathroom faucet device. Types, designs and repair of mixers

The mixer, indisputably, is an integral part of any bathroom. It is used for hot and cold water supply and comfortable use of a shower or bath. Thanks to such a device, you can easily adjust the water head and temperature. A special switch helps to redirect the flow from the bathroom to the shower head, which (it can not be overlooked) is convenient.

Like other mechanical devices, mixers often break down. This is explained by the rapid formation of scale. Repair this design easily with your own hands. It is not too tricky, and the problem is eliminated in a couple of minutes.

In this article you will get acquainted with the types and types of mixers, as well as find out what their device is, and how to eliminate unwanted breakage of the mechanism yourself.

Species diversity

Knowing how the mixer for the bathroom and shower is designed, you can understand the principle of its operation and understand the problems that have arisen due to breakage. All bathroom faucets are divided into three groups:

• Sensory ones are those that react to motion by activating a photocell built into the device. Self-repair of such a device is difficult, therefore it is better to entrust such a device to the hands of specialists. The most recent development is the sensor mixer for the bathroom. The price for such products in Russia starts from 10,000 rubles. It is usually higher than other types of bathroom faucets.

• The valves consist of three structural parts: a body, a spout and a valve. Adjusting the pressure of the water jet is done manually. The old Soviet models were assembled with rubber gasket during assembly, modern ones are equipped with ceramic plates.

Important! Old models of mixers with rubber gaskets are still on the market, so choosing the plumbing for your bathroom, give preference to ceramic faucets. Such a device for a bathroom faucet is more durable and practical.

• Leverage models of mixers have recently been very popular. The design of this mixer is presented in the form of a casing, a spout and a ceramic or ball cartridge in which cold and hot water are mixed until the temperature you have chosen is reached. The device of the mixer for a bathroom with a cartridge is not subject to disassembly. If the cartridge is out of order, you can restore the bathroom faucet device only by replacing an unusable element.

Shower-type lever-type mixers consist of:

• Control handle, which performs the function of the regulator of the head and water temperature;
• Housing;
• Nut, which acts as a latch of the inner element of the cartridge;
• Cover of the body, which protects the cartridge and gives the design a more aesthetic appearance.

The most common causes of breakdowns

Having studied carefully the device of the bathroom faucet, you will be sure that it is not such a problem to fix it. It is important only to understand the causes of crashing. There are several main factors affecting shower faucets and provoking product breakdown:

1. The device of the mixer of water for a bathroom poor-quality. This means that the product is assembled from low-quality components and consumables.
2. Use of out-of-date consumables, whose service life is much lower than modern paronit or silicone gaskets. In addition, they are less vulnerable to deformation and drying.
3. Low-quality piped water.
4. Hard water, which adversely affects the wear resistance of the internal parts of the mixer. Scum can form not only inside, but also outside, adversely affecting the bathroom faucet. Bronze and chrome - a protective coating for sanitary products that protect them from the formation of scale and the development of corrosion processes.

Leak in the area of joining the spout and the body

The device of a bath mixer with a single-lever shower can break during long-term or uninterrupted operation. You can repair this design yourself.

The malfunction associated with the breakage of the mixer can be manifested as a leak in the area of the hull and spout. Plumbers face such a problem almost every day. Rubber gasket, isolating the area of the junction of the gander with the body, is in constant rotation, which leads to a rapid breakdown. When the gasket breaks down, the gander starts to leak. To correct such a problem, you can replace the rubber gasket with a silicone gasket, whose service life is longer.

Bathroom faucets firms offer a wide range of accessories and consumables for products, so you can easily find spare parts for mixers of the required model.

Running water from under the control lever

Such breakdowns are typical for single-lever mixers, which is caused by the wear of the cartridge. Inside the device, scale can accumulate, then the bath mixer breaks. Bronze is a coating that protects the inner surface. When it overheats, the protective properties are lost. In this case, it is better to give the mixer to the workshop, where disassembly and recovery will be done qualitatively. If a single-lever bath and shower faucet is installed in your bathroom, you can determine the breakdown of the cartridge by the following features:

• The lever can hardly be turned;
• The temperature of the supplied water changes spontaneously;
• There is no water supply;
• The water in the tap does not overlap completely.

If you notice one of these problems, you must replace or repair the cartridge. Sometimes you have to buy a new mechanism, in the event that you can not restore the bathroom faucet. The price of cartridges depends on the type of mechanism and the type of mixer and fluctuates between 60 and 100 rubles.

How to fix the mixer yourself

To independently adjust the operation of your mixer, follow the instructions:

1. Remove the red-blue plug from the housing.
2. Remove the crane lever by loosening the fixing screw. Use a small Phillips screwdriver to do this.
3. Remove the lever and unscrew the decorative cover.
4. Pull out the broken cartridge.
5. Mount the new device inside the box and assemble the mixer.

Important! Pay attention to the small protrusions on the cartridge - they must coincide with the grooves knocked out on the inside of the case. If you mount the element incorrectly, the mixer will flow.

Leakage of the tap in a two-ventilated mixer

The reason lies in the deterioration or damage of the gasket, hidden in the crane-bux. Sometimes, the crane-box itself is destroyed. If your bathroom has a mixer and you do not know how to fix it inexpensively, do it yourself.

Rapid recovery of the mixer is performed by shutting off the water:

1. The leakage valve is released from the plug.
2. Unscrew the holder, by means of which the valve is attached to the body of the product. After this, using a tool (carabiner or wrench), the crane-box is twisted.
3. Depending on the degree of failure, the crane-bug or sealant under it is replaced.
4. The new parts are replaced with old ones, after which the mixer is assembled.

How to prevent leakage of the regulator "faucet-shower"

In the place of the regulator, responsible for switching the flow of water from the tap to the shower, there is another sealant, which is often damaged. To fix the mixer, faced with such a problem, you can disassemble only one of its switches. To restore the mechanism you will:

1. Remove the button / switch. Use the pliers for this and, while holding the rod in a fixed position.
2. Remove the valve from the stem.
3. Pull out the damaged packing.
4. Install the new consumable in place of the old one and place the switch with the stem in place.

Breakage of the button "faucet-shower"

If after pressing, the button does not return to its natural position, then the spring inside it is broken. In this case, the button is disassembled according to the scheme described above, and the broken spring is removed and can be replaced. If you press the button, the water continues to pour from the tap and from the shower - this indicates a breakdown of the stuffing box, which is located in the switch stem.

In this case, you need to do the following:

1. Remove the button / switch.
2. Pull out the stem.
3. To change an epiploon.
4. Assemble the switch back.

The shower hose is flowing

Damage to the hose laying causes the leakage of the hose. All that needs to be done to solve the problem is to buy a new gasket and make a replacement for the old one.

If the cause of the failure of the mechanism is serious, and you can not fix it, you will have to buy another basin mixer. Bronze inside and chrome plated outside will help the new product last longer, protecting it from the formation of scale and rapid wear of parts.

Having studied this material and got acquainted with the main causes of the breakage of the mixer in the bathroom, you will turn into a real master of all trades and will be able to eliminate the problem in minutes without resorting to anyone's help. Just use advice and recommendations, and you will all get it right.
