How to fix a faucet in the bathroom, repair single lever mixer

Flowing in a kitchen or bathroom faucet - a phenomenon which at least once faced virtually everyone. Long flowing leave without attention does not recommend any Plumber: not only that the constant "drops" may leave a mark on the most sensitive coatings sinks and baths, so more and the monthly cost of water will increase significantly, and this has impact on utilities payments. In this article we'll show you how to repair "potokshy" mixer.

Possible causes of leaks

in plumbing experts have identified all four main reasons for the formation of a leak in household mixers:

• output resource seals and gaskets device;
• natural wear of the locking member (axlebox-tap or cartridge);
• incorrect assembly and installation;
• manufacturing defects.

There are two most common types of faucets installed in modern apartments and housing houses: dvuhventilnye and single lever, the latter being, in turn, come in a cartridge or a ball type.

Next, we consider the nuances of repair of each type in more detail.

How to fix a twin valve, if it flows

The first thing to determine when repairs dvuhventilnye model - type his head parts. They are poluoborotnymi (flow occurs due to wear or damage to the ceramic locking plates) and valve (flow appears due to wear of the stem gland).

Reference. head parts valve mechanisms are also referred to as "thumbscrews".

To fix potokshuyu gate Bux, just enough to change the rubber sealing element at the tip of its stem. You will need:

1. Remove the valve handle.
2. Release head parts by means of a suitable key.
3. Remove exhaust their packing and, if necessary, clean it, the location of rust and dirt.
4. Fit new sealing element and make the mixer assembly in reverse order.

If we are talking about poluoborotnyh head parts, the mechanisms of their repair will look a little different:

1. Prepare a new journal box and cut off the water.
2. Disassemble the decorative cap valve by prying it with a screwdriver or unscrewing in the case of a thread.
3. Gently unscrew the screw securing the valve (the situation may be complicated if soured screw rust and firmly "sat down" in the valve).
4. Unscrew and remove the worn Books.
5. To put in its place a new design and assemble in reverse order.

Important! Do not overdo it with the tightening axle boxes: over time, the compound may corrode, and remove it becomes much more difficult.

Repair of single-lever mixer

Single-lever mixers with the cartridge in recent years become one of the most common setting for virtually any residential or industrial premises. The cartridge of such a device has the form of a small "barrel" with rotating ceramic elements inside the main function - a device to block the incoming water.

If the water flows from the lever or from the crane itself or knob pereklinilo or mixer stopped "catch" average temperature (tap pouring boiling water or ice spray) - made replacement of the entire cartridge device as interchangeable elements for such models are not provided.

To change the cartridge is a single-lever mixer with a new need:

• block podvodku water to the mixer;
• with a screwdriver to pull the plug, closing the latch handle (usually performed in the form of blue-red circle, indicating the water supply side);
• loosen a couple of turns opened under the screw cap, and then remove the handle mixer;
• unscrew the domed pad under the handle;
• suitable wrench turn the nut-lock under the cover plate;
• get wear cartridge and taking it with you, ask the seller to plumbing store to pick up the same;
• mount bought cartridge into place, tighten the nut-lock and assemble the mixer in the reverse parsing algorithm.

Important! At the bottom of the cartridge positioned special protrusions to be inserted into the slots in the valve body. Otherwise, it may break at the opposite barrel assembly crane.

Despite the fact that the ball valves are one of the most reliable, leak when worn locking balls happen and they have. The algorithm works by replacing it looks like this:

1. Otkovyrivaetsya decorative rivet, and then gets out locking lever mixer screw.
2. Dismantled bill cap and nut, hiding behind it.
3. Maximum gently pulled from the disassembled construction cam ring in which the shut-off ball.
4. The ball is pulled out of the washer (the latter in case of wear should be replaced) and inspected for wear. If the state of the ball is satisfactory, you can do without replacing it by treating it with a soft cloth sprinkled with detergent (not abrasive).
5. If the ball has serious defects in its place is put a new and a reverse assembly of all the elements.
6. Special attention at the assembly stage of the crane must be paid to the correct installation of the springs in recesses intended for them.

other faults

Most faucets for bathrooms are equipped with a special switch that lets you aim the flow of water or the tap or the shower. Such switches may be a pendulum or a push-button and, if the water is flowing at the same time out of the shower and faucet - the problem is clearly in them.

In the case of the pendulum (as it is called rotary) switch procedure for replacing worn out his slide resembles the process of replacing the pads on Books, which we have already discussed above. As for the push-button switches, then they most often leads pad, which can be changed as follows:

1. Using an adjustable wrench, unscrew the button.
2. Replace stem sealing washers with new ones.
3. Insert the key into the housing and tighten it tightly enough.

If the button is jammed in any state, the cause is often wear the spring. In this case it is necessary to replace the entire switch, dismantle it and put a new one.

Another common failure is a leak at the connection of so-called goose soul to the mixer. To fix it, you must unscrew the nut fastening the gander and using tweezers to remove the worn gasket.

Note that the fixing nut gander is not removed from it, so to get a lining can sometimes be difficult. If goose with a new gasket is included in the mixer body too hard, it is possible to lubricate the ring sanitary sealant integrally sealing the connection.
