Happy New Year,
I have a problem with the hot water.
Our hot water works via a hot water calinder with inputs from a boiler and a solar panel loop.
The cylinder is made of copper and the inflow has a pressure reducing valving with a 2.1 bar rating. It has a 18l expansion vessel connected nad that was serviced and the pressure in there is about 1 bar. We also have a pressure and temperature relief valve on the cylinder, but they hardly ever / never get triggered unless for testing.
The cylinder heats up nicely and when we switch the hot water on in the shower or kitchen tap, we get plenty of water pressure. after a few minutes this nice water pressure evolves into a little dribble and when you wait the pressure will recover again but not to the original pressure.
There is no inflow obstruction / restiction. It is all 15mm pipe. The cylinder with all valves was installed together with the solar panel about 20 years ago.
I am wondering whether this odd water pressure is a sign of the pressure limiting valve being on its way out?
