Worcester 35 CDI two different shower valves, I of which is brand new, both showers run hot for say 5mins then start to run cold for 3-4mins then hot then cold again, no taps being opened elsewhere in house
any help please?
both showers NOT running at same time
kitchen tap ok. just when shower on ,boiler kicks in and outDoes the boiler stay alight or does it go out as well
Also is the kitchen hot tap doing the same ?
def. plumbed rightHot and cold piped up correctly to the showers ?
thinking more of boiler issue? diverter valve??Balancing issue between hot and cold?
def. plumbed right
1-grohe thermostatic concealed 1- crosswater kai 3 thermostatic valveAre they bar showers ??
noSounds like a bit of cross-flow from the cold supply to the hot water from combi.
Do you have any check valves on pipes to shower valves or non return valve on hot water out from combi?
cheers,
Andy
filters very cleanDo you know if the filters were cleaned ?
Doesn't sound like a boiler issue as the hot tap is fine
