repair single-lever mixer when it detects a leak from under the arm

Such leakage, usually is caused by malfunctions in the cartridge mixer.First, let's understand what a cartridge?

cartridge - is collecting cylinder with three holes;in one hole comes hot in another - cold water, and the third mixed water is discharged.

By type used for mixing hot and cold water mechanism, cartridges are classified into ball and ceramic.In addition, the top of the cartridge is located rod to which is attached a lever mixer.Just at this point, and leakage occurs.

When you need to change the cartridge

  • not served either hot or cold water;
  • water temperature varies arbitrarily, without changing the position of the lever.

First of all, we recommend you to buy a new cartridge, remove the old and together with it as a pattern to go to the plumbing shop.

Choosing a new cartridge

As we mentioned above, it is important to pay attention to the quality of purchased plumbers you. Prefer cartridges tested European firms, and try not to get to the scam tricks, copying execution of well-known brands.

As a rule, if you do not set the whole water system in the house or flat, you have no choice, choose what type of cartridge.The fact that, despite the variety of models, there are only two basic types cartridge - and a ceramic ball.

plus the use of ball cartridges is considered to be the ability to disassemble the cartridge itself and to repair it if necessary.

Ceramic same cartridge can not make out, it is to be completely replaced, but the ceramic plates in it are more durable and not prone to the negative effects of hard water.If initially the faucet mounted to the calculation for the use of ball cartridge, ceramic, you will not be able to deliver.And vice versa.

But back to the issue of repair single-lever mixer when it detects a leak from under the arm:

1. Remove the plug with a screwdriver, indicating the direction of the cold and hot water.

2. Under it you will find a screw.Carefully unscrew it with an Allen key or a screwdriver of a suitable size so as not to damage the threads.If you fail to do this carefully, use a drill with a thin bit.

3. Remove the lever from the mixer body by pulling it up.

4. Remove the decorative element with mixing by hand or with pliers.

5. Remove the nut, which presses the cartridge itself directly to the body of the mixer.To do this, first use an adjustable wrench, and then gently loosen his hands.

6. All.Now you can pull out the old cartridge, boldly go with him to the store and buy yourself a new one.

7. To install a new print cartridge, follow the steps described above in reverse order.

The mixer has another gasket, similar to the one which is located between the gander and the body of the mixer, which we mentioned above.This second gasket is installed between the mixer casing and the switching lever.It also tends to wear out over time.

Replacing a pad is almost the same pattern as the previous:

  1. Remove the lever.If you can not do this, check the fastening screw.If there is a screw, you must unscrew it first, and then remove the lever itself.
  2. Remove the remnants of the old gasket and place it on a new place.
  3. Wrap the thread tape or flax with pasta.
  4. Place the lever to its original position and, if necessary, tighten the screw.

But their main disadvantage is that they are extremely difficult to repair. We do not recommend doing this yourself.It is better to try to find an experienced professional who understands this issue.Sensors You will hardly be able to repair themselves - most likely, you just simply break the faucet completely.

If we are talking about some minor shortcomings, such as clogging of the aerator, you can easily cope with this problem alone.
