Hi...following an updated installation I have a problem using two showers as I could before. We don't run both showers at the same time, but only use one shower after each other. When we have used one shower it effects if the other can start up afterwards. The start is very delayed or can only be made to happen by turning the thermostatic valve knobs side to side several times.
If we just stick to using one of the showers it starts up straight away every time.
Old installation had two showers, one in the main and other in en-suite, both tee'd off one Bristan Jetforce 55 and using Mira valves. We never had this problem.
The new installation is practically the same except for replacement thermostatic valves (Phoenix SV024) and new shower heads.
I'm told that the pump is at fault, and I must change it to a pressure vessel type. This may well work fine, but could flow resistance of the Phoenix valves be the true problem and if so is there a simpler fix?
