Crane for the filter - learn to properly connect the water
Formally, the water in the apartment is already purified, that is, it can be drunk without harm to the body, at least theoretically. In practice, the situation is completely different and the liquid from the faucet is of little use to the body. Most often, this problem is solved by installing a special filter under the sink, in which case you will need an additional tap to supply drinking water.

Why do you need a separate tap
The issue of cleaning tap water is solved by buying a filter unit. In this regard, several options are possible, but for the house in terms of the ratio of cleaning quality / cost / reliability, it is optimal to install a filter under the sink in the kitchen.

This design provides the maximum degree of purification, while its resource before replacement is of the order of several tons of water. But the question arises of the consumption of purified water, because in the kitchen the sink is used both for washing dishes and for washing vegetables and fruits - it is simply illogical to use purified water for these purposes. The way out of this situation can be considered a separate faucet for the filter.

As a result, drinking water is not wasted, and the cartridges will last longer. Of course, you can instead use filter nozzles or ordinary jugs with a filter for cleaning, but the effectiveness of this solution will not be at its best.
Note! The only drawback of installing a second crane can be considered not quite aesthetic appearance - not always 2 such devices on the sink look appropriate, and in the future it will be impossible to get rid of the second mounting hole.

From a technical point of view, the installation is no different from the installation of a conventional mixer and all the work can be done by hand. A small difference lies perhaps in the fact that it is necessary to make an additional hole to connect the faucet.
Types of filter taps
Similar devices can be divided into 2 groups:
- simple models for separate supply of purified water;
- double - can be considered the best solution for the filter. Such a device is suitable for the supply of both ordinary and tap water. You can install it instead of the usual mixer, and the only cost limiter can be a high cost - the price of such a device can easily reach 10-15 thousand rubles.

Double taps are also known as "double spout". Such devices can be produced with 1 and 2 spout pipes, from the point of view of ease of operation, both options are about the same, so when choosing to pay attention to the aesthetic side.

As for the material from which it is made, manufacturers do not offer anything unusual, models are available from:
- brass;
- of stainless steel;
- Bronze - such devices look solid and look great, a bronze faucet for a water filter creates the effect of antiquity.
Note! If a double spout model is used, there is no need to make another bore hole in the sink, so the installation procedure is somewhat simplified.
Installation process
Installation of a separate tap for purified water can be divided into such stages as: drilling in the sink (and maybe in the worktop), the installation itself, connecting it to the filter installation and testing the tightness of the joints.
In general, work is recommended to perform in this order:
- First you need to do the preparation of the seat for the installation of the crane. You can advise to start with a small diameter drill and gradually increase it to the desired size, if you try to immediately drill a large diameter hole, that is, the risk of chipping the table top, you need to drill a stainless steel without strong pressure;

- After that, the installation manual requires organization of water supply to the filter. To do this, a tee is slammed into the pipe supplying water to the mixer, through a side outlet and the filtering unit is powered. Naturally, the water supply must be shut off before that;
- after assembling the filter itself, it connects to the pipe tee for water supply;

- then the installation is done directly on the countertop sink or sink (the hole should already be drilled to this stage). At installation, gaskets and a fastening washer are used, first a gasket is laid directly onto the hole, and another one is laid under the fastening washer. Before final fixing, it must be leveled with respect to the sink and only then tighten the fixing screw;
- after that it remains only to connect it to the output of the filter (plastic hoses with appropriate markings, as a rule, are part of the components that are supplied with the filter).

A double tap for filtered water makes it somewhat easier to install and keep the sink or countertop intact.
In this case, when installing the filter, you will need to replace the old mixer with a new analogue, but with a double spout, the work in this case is performed in this order:
- First, the old mixer is dismantled, to do this, the fixing screw is removed from the bottom of the sink, and the hoses of the supply pipes are disconnected. The place where it was located is cleaned with sandpaper from any impurities;

- then, in the same way as with the installation of a conventional crane, a double analogue is installed. The feed tubes for plain and purified water are connected through the mounting hole (it is important not to confuse the holes to which you are connecting).
Possible leaks may not be immediately apparent - it may take more than one hour until the liquid can seep through the joints. Therefore, after connecting the filter, it is recommended to check the tightness of the joints in a day, both in the place where the pipes are connected to the installation and in the places where the filter outlet is connected to the mixer. If necessary, the connection can also be sealed with a FUM tape.
Summarizing
A water filter is not uncommon, such devices can be found in many apartments. Installation of such a design is simple, but requires the installation of an additional crane, which is not always convenient. Alternatively, you can consider installing an analogue with a double spout, anyone can cope with this task, you just need to monitor the tightness of the joints and follow the proposed instructions.
