It is the most used and the most efficient process. But, bulky and placed at the water meter, the water softener is not always easy to install.

The softener settles on the general arrival of the house, near the meter, before the boiler or the balloon. Before you put one, check the water pressure in your pipes. Depending on the model, it should not be less than 1 or 1.5 bar. To measure it, buy a pressure gauge or call a plumber. Then measure the hardness of the water with a TH-test kit. The result will allow you to better adjust your softener. Totally softened water is not desirable because calcium and magnesium in water are necessary for health. The ideal is to reach a TH of 8. Before you start, do not forget to shut off the general water supply!

The device used here has a dual feature: it operates without electricity and includes two filters (impurities and activated carbon), permanently active thanks to two bottles of resins that walk alternately. When one is in regeneration phase (inflow of salt water), the other takes over.
In any case, think of the maintenance of the machine, to prevent bacteria from developing on the resins and contaminate the water.

How does water softeners work?

The softener consists of two tanks, one containing mineral resins and the other salts. It uses a physico-chemical process: the resins exchange their sodium ions against the calcium and magnesium ions of the water. They thus capture the tartar. Once saturated, they are regenerated by salts dissolved in water (brine). The limestone thus fixed is returned to the sewer.

An anti-scale station, more economical and less cumbersome than a softener, works by filtering. This simply prevents the limestone from becoming tartar and thus settling on the pipes.
The apparatus comprises two filters: the impurity filter retains fine particles in suspension (sands, mud) and the scale filter contains silicophosphate beads which counteract the amalgam of calcium and magnesium. It is easy to install, closer to the main water supply and in an accessible place. The filters are connected according to the bypass technique.
If pressure is too high, it is best to install a regulator before the station.

Screw the connections onto the main cylinder (water intake limestone, water softened). Place the pin.

Screw the lime water and salt water inlet connections (from the salt container).

Screw the connection fittings between the two canisters which work alternately.

Set the float of the brine tray to its hardness. The harder it is, the more water you need in the tank.

Place connecting elbows on the bypass. Tighten the nuts. The black knob serves as a stop valve.

Loosen the screw under the black knob so that the water is not completely softened.

Mount the bypass: screw the plates on the support. Cut and connect the water inlet hose to the bypass.

Put the copper connection between the bypass and the house supply pipe (fresh water).

Connect the bypass to the main tank. The water arrives limestone at its level and comes out softened.

Connect a hose from the canister to the drain. A loop creates a siphon that avoids lifts.

Connect a hose from the canister to the brine tank. The salt-laden water regenerates the resins.

Reconnect the water. When its level exceeds 2 "of the grid in the brine tank, pour the salt.

What interview?

• The effectiveness of a softener depends on its maintenance. It must be regularly reloaded with salts and controlled to prevent the proliferation of bacteria. Be careful, the softener can make the water too soft. Analyze it periodically and carefully observe the maintenance procedures.
• After a prolonged absence, trigger a regeneration before using the water.
• Check the filling of the salt container and break the crust that forms there.
• Have your device checked once a year by a professional.

Is it true that water treated with a salt softener is not drinkable?

Christian Pessey's answer:
In public buildings (ERP), water treated with a resin softener is not considered safe because of potential bacterial risks.
In a house, if a softener is installed, it is better to do a double installation reserving non-softened water for food consumption.

Softener or anti-tartar?

My water is very calcareous. Is it better to install an electronic anti-scalar or a conventional softener?
Christian Pessey's answer:
Only salt softeners guarantee the elimination of limestone, attested by official tests and notices.
The ability of various electronic or magnetic systems to hold limestone in suspension and prevent its redeposition in the lines and on the resistors of the devices is not certified.
I will remind you that a limestone water is never harmful to health, while a too soft water is corrosive for the pipes and vehicle of the heavy metals.
