one of the showers is only 3 months old - could the cartridge be faulty so quickly?
Have just done some testing and the gauge on the prv is reading 5bar with no load - if I turn a hot tap on the boiler kicks in it shoots up to 9.5bar....
Hi,
I am having a problem with both thermostatic mixer showers in my house.
Both run cold\luke warm when used.
If i turn on the hot tap the water comes out boiling.
Mains pressure is good, and i have 1.5bar indicated on the boiler.
The only way I can get the showers to work...
