How to install the faucet on the sink
Before you install the mixer on the sink, you will need to decide on the type of connection used to connect the device to the pipeline, suggesting a choice of two possible options:
- connection with flexible hoses;
- direct hard wiring.
Immediately, we note that the choice of a particular connection option depends primarily on the piping layout used in the bathroom or in the kitchen. In this article we will consider the case of liner with the use of flexible hoses, since it is used most often.

To dismantle the old and install the new mixer with a flexible connection, you will need a minimum set of tools consisting of the following items:
- flat and cross-head screwdrivers;
- pliers;
- adjustable wrench;
- FUM tape or flax fiber.
Dismantling the old mixing device

Installing the mixer with your own hands should be done only after the valves on the cold and hot water supply pipes (in front of the counters) are closed. After that, it will be possible to proceed to the removal of the old mixer, all dismantling operations of which are performed in the following order:
- First, the ends of the flexible hoses are disconnected from the side of the cold and hot water supply.
- After that, using a wrench or a pair of pliers, the nut fastening the mixer to the shell body or the sink is unscrewed.
- After removing the nut and removing the washer, the mixer can be pulled towards itself, simultaneously pulling out both supply hoses through the hole in the sink.
In some models of mixers, a simple screw is used as fasteners, which, when dismounted, is turned off with a screwdriver.
At this disassembly of the old mixing device can be considered complete.

Before installing a new device, it is advisable to familiarize yourself with how it is properly assembled, during which flexible hoses are screwed into the mixer housing (from the water supply side). When assembling, it is necessary to pay attention to the special rubber cuffs installed on the fittings of the liner, as well as to the fact that some models use fastening studs with a rubber sealing ring necessary for fixing the mixer at the place of its installation.
Installation procedure

Before installing the distributor on the sink, the installation site is carefully cleaned, and then a special chemical composition (sealant) is applied to it, ensuring a reliable connection.

The installation procedure for the mixer is as follows:
- First, the hoses screwed into the mixer are pulled into the mounting bore, after which the device itself is installed in the previously prepared place for it.
- After that, under the sink, a presser washer with a rubber gasket is put on the threaded fitting, and then the fastening nut is tightened, tightened by hand with a little effort.
- Sometimes a special screw or stud (studs) with an overlay and rubber gasket is used to mount the mixer, which are also hand-tightened with limited force.
- For the final fixing of the mixer at the place of installation, you will need a previously prepared tool with which all fasteners are tightened until the device body is firmly fixed.
- At the final stage of installation work, the flexible connection of the mixer is connected to the hot and cold water pipes. In order to increase the reliability of the threaded joints formed at the same time (their tightness) it is recommended to use FUM tape or flax fibers.

When connecting a flexible connection to the water supply pipes in the kitchen or in the bathroom, you should act extremely carefully, avoiding the “overtightening” of the attachment and damage to the gaskets.
It is necessary to follow the correct connection of flexible hoses: hot is connected to the left, cold water to the right.
Connection check

Upon completion of the installation of the mixer, it is important to ensure that all the joints prepared by you are tight (as there is no leakage in them).
To do this, the knob of the mixer is set to the “off” position, after which the valves for supplying water to the apartment (first cold and then hot) are opened. After filling the canals with water, it will be possible to make sure that there are no leaks at the junctions of the water distribution device with flexible hoses.

If there is a small leak in any place, the nut of this connection should be tightened with pliers or a wrench. The installation of the faucet on the sink can be viewed in the video.
