Hi there, we had a new hot water cylinder installed at same time as solar fitted and while hw & ch system pressurised. First of all just a pressure reducing valve was added but we pointed out the water was hotter than regs, so they then fitted a temp blending/ controlling valve to bring it down to regs.
Now we've got a problem that I tried to get sorted but the plumber robbed us off saying I just needed to turn stop Cock down and harrassed us into paying. That was a year ago!
Turn on hot tap and it runs at much higher than operating pressure but its cool at best. This goes on for 30s then there is hammering in the pipes but when this stops the pressure drops back to operating pressure (a bit low imho) but nice and hot.
What causes it?
Can this be sorted by trying out different pressures (tried a few but not worked)?
How can I get it sorted as we waste tens of litres of water every time we need hot water.
Thanks people in advance!
