In the shower ends abruptly and hot water goes cold: what to do?
Friends, Hello! This is the second article in a training cycle "Self Plumber". The last time I spoke, because of which the hot water is interrupted by cold, this article will tell you how to avoid it.
Go!
If your home is connected to a central hot and cold water, the first thing you need to do - check the pressure in the tubes Cold-water and hot water.
Accordingly, if the cold pipe pressure 2 bar, and a hot - 5 bar, pipe, hot water supply is necessary to reduce the pressure reducer to 2 bar.
Nuance: Minimum hysteresis (differential pressure) gearbox starts at 0.5 bar. If you have 2 and 2.4 bar in the pipes, the gearbox does not work.
If the pressure difference is large, the installation of the gear will solve your problem with intermittent hot water.
And what if it is less than 0.5 bar?
There is a solution for you. You need to spend (4,000 rbl.) And buy three-way thermostatic mixing valve of any brand.
The main choice of nuance - carefully looking at the operating temperature:
- 35 - 60 ° C;
- 20 - 43 ° C;
- 30 - 65 ° C;
This is the range in which the thermostat is working - is the temperature that it can skip through itself.
By the way, comfortable temperature for showering - 38,5 ° C, so a higher temperature, it seems to me to anything.
