ok, quick update. tried lowering the temp on HWC but still same result of pump runs for about 6 mins and then starts scavenging. Does the thermostat on the HWC operate the immersion heater cut off? because i generally heat my HWC up using my boiler.
Gunna try the scenario of emptying all the hot water from the HWC and the gunna try running the shower with the mixer valve turned to hot and see what happens.
any other thoughts would be greatly appreciated.
