Abnormal shower issue: switches from hot to cold
We've had British gas come by several times to inspect the boiler and several plumbers come by to check the piping system - no one understands why this is happening. It only happens in the kitchen sink and shower, both of which have been inspected thoroughly. Any ideas or thinks I should check?
Hi i would be looking at any non return valves you may have on your taps / showers , If you have a combi boiler this would be even more so .
If you can isolate each tap/shower and then run the system you may find its the cause ... Good luck
