How to change the tap in the kitchen
The faucet located in the kitchen is used every day, so it is not surprising that it fails much more often than the faucet installed in the bathroom. The most common problem of a kitchen tap is its leakage. It can be said that a dripping faucet is the homeowner's money, which is gradually merging straight into the sewer. In most cases, the main cause of this problem is a worn rubber gasket. This happens due to poor quality of the material or an error made during the assembly of the crane.
Here are the most common types of faults:
- The flow of the mixer itself.
- Leakage at the spout.
- Flow from the flywheel area.
- Water from the tap comes only a thin stream.
- When the tap is open, a hum is heard.
- The mixer is unstable.
- Lever malfunction.
The process of self-replacement of the tap is not so difficult, if you even remotely have an idea about the structure of the water supply system.

Choosing a new mixer
All models of kitchen faucets are divided into three main types:
- Two-valve
- Single lever
- Contactless
Two-valve - classic mixers. They are distinguished by their simplicity and rather strong construction. There is a special mechanism that is fixed in a metal case (bush). Responsible for the water supply and running due to the rotation of the valve.
Single lever - beautiful appearance and comfortable design made this type of cranes one of the most popular. Two valves came to replace one lever, responsible for supplying both hot and cold water.
Contactless - kitchen faucets, in which a special sensor is installed. Thanks to him, it became possible to get rid of the manual elements of the crane. The sensor reacts to the presentation of the hand to the tap and starts the flow of water and automatically stops it if the hand is removed.
Required tools
To replace the kitchen tap, a pair of tools that are practically in every home are enough for you:
- Adjustable plumbing wrench, or a set of wrenches.
- Set of screwdrivers.
- Knife or scissors.
- The vessel in which the water will merge.
- It is advisable to equip with sandpaper or a file. It may be necessary to fit the plumbing elements with his own hand.
- If necessary, use a flashlight.
Although there are quite a few different types of cranes, almost all of them are similar in design and the process of replacing the crane will be based on two stages: dismantling the old system and installing a new one.
Dismantling the old system
- First of all we block the water. It is advisable to open the tap and make sure that there is no water.
- Then disconnect the siphon from the sink and remove it.
- At the next stage we are engaged in disconnecting flexible water hoses. from the pipeline with a suitable key.
- Unscrew the nut, which fixes the threaded pin.
- Remove the mixer together with all flexible hoses.
Installing a new system
It is important to bear in mind that when replacing a water faucet, it is necessary to change the old liner. The kit of the new mixer should include two pairs of special pipes that can be used as a new liner.
- We unpack the new crane and check the equipment. We connect to it new (or old) supply pipes.
- Install a rubber gasket under the mixer and attach it to the car wash.
- Through mounting holes skip the supply pipes.
- Bottom install rubber seal and pressure plate.
- Install the locking nut and tighten it with a key.
- Put the sink in place, simultaneously connecting hoses and siphon.
- We check the performance mixer and no leakage.
Mixer materials
Chromium - too thin and sensitive to damage material. When installing chrome faucets use specialized soft pads.
Alloy steel is the most durable material. However, there is a silumin alloy sensitive to damage. Therefore, when selecting parts, it is important to find out the composition of the alloy. The ball valve is made from this material.
Ceramics - although earlier ceramic objects were rather fragile, modern analogs are rather strong and reliable.
Self repair
Mixers can have different designs. Let us analyze the repair of each type of crane separately.
Single lever
The elimination of leakage of these types of cranes requires their complete disassembly.
By tradition, before starting work we shut off the water and drain its remnants.
- Remove the cap with a knife and unscrew the screw hidden behind it.
- Completely remove lever and cap.
- Then we get the cartridge and inspect it for a sign of obvious defects.
- We check all the remaining small details of our design.. We clear rubber seals, gasket, spring from accumulated raid. If a broken part is found, replace it with a new one.
If the problem was in the cartridge itself, then it should be replaced with a new one. It is important to buy a similar item to match all the grooves and holes. In cases where the cause of the leakage of the valve is the wear of the gasket, it should be replaced with a new one in the same way. Note that the diameter of the gasket must be selected in such a way that it is slightly larger than the socket.
In cases where water flows directly under the spout, attention should be paid to the sealing rings. They are most likely the cause of this breakdown.
Two-valve (classic).
Two-valve mixers are the most common.Here is the order of their repair work:
- First of all we block the water.
- In order to relieve the valve from strong pressure, we translate the valve to the on state.
- Remove the caps and unscrew the screw securing the flywheel.
- Unscrew the fastening nut and remove the neck.
If the problem lies in the valve head itself, replace it with exactly the same new one, or a similar size.
General recommendations
In the process of exploitation of technology, small or small faults appear sooner or later. There are certain preventive measures that prevent the early occurrence of breakdowns and prolong the service life of the mixers.
- It is necessary to choose reliable materials.. The most attractive by this criterion is brass.
- Single lever mixer has several advantages: usability, reliability and easy repair, which is achieved through a special design.
- It is recommended to install water purification filters.. This allows you to get rid of the dirt coming from the water supply, and prevent clogging of parts of the crane.
- Consider that when establishing the details of the plumbing systemyou do not need to tighten them too much.This can lead to the breakdown of the threaded connection and the whole system will have to be changed to a new one.
- After replacing the valve gasket, do not completely open the valve. Do this gradually, checking for signs of leakage.
- In order to remove scalemost commonly used is acetic acid.
It is important to choose the correct size of the liner. They should bend in the form of a semicircle, and not wring.
The best option is a liner length of 86 cm. It is strongly not recommended to purchase silumin tubes (aluminum alloy with silicon). This material is famous for its lack of reliability. Flexible connections should be installed at the same time as tap taps, as they can be easily ruined.
Replacing a kitchen faucet with your own hands is not so difficult as it might seem at first glance.e. Even a woman is quite capable of coping with this matter, the main thing is the correct procedure and precautionary measures. The product is very easy to spoil, so you need to act carefully. Replacement is made using tools that are in almost any home. In extreme cases, they can be purchased, because they are inexpensive.
If the crane has non-standard forms of parts, the dimensions of the gasket do not correspond to its other analogues, then the broken part or the worn “gum” should be kept as a sample.
