Installation scheme of a water softener after a storage tank with a bypass line and drainage

This scheme is used in systems where municipal water first enters a storage tank and is then supplied to the house using a pump.
Incoming water passes through an inlet service valve and a PP mechanical filter with a 5 or 10 micron cartridge. This helps protect the storage tank, pump, softener control valve, and the downstream water supply system from sand, rust, and suspended particles.
After that, the water enters a storage tank, where a water reserve is created. The pump then supplies the water under pressure to the section of the system with the softener.
The softener unit includes:

• an inlet service valve
• an outlet service valve
• a bypass line around the softener
• a drain line for discharging water during regeneration

In normal operation, water passes through the softener, where hardness salts such as calcium and magnesium are removed. The bypass line allows water to be supplied to the house while bypassing the softener during maintenance or in case of an emergency. Service valves allow the equipment to be isolated and simplify maintenance.
After treatment, the water flow is split into two lines:

• one line is supplied to the boiler, where the water is heated and then enters the domestic hot water system
• the second line supplies softened cold water directly to the house water system

This configuration helps protect the boiler, household appliances, faucets, shower glass, and internal pipes from limescale formation, and also improves the overall comfort of water use in everyday life.
