Dear all,
I've just had a new Hudson Reed (thermostatic, twin controls) shower installed with new tank, pipework and a 3bar stuart turner pump (twin). Its set up to power the other shower downstairs too.
The problem is that the new shower sometimes doesn't have sufficient flow- through to kick off the pump. The one downstairs always kicks off fine.
On investigation to check the flows... with the pump turned off if I over-ride the 38oC stop then the hot water comes through ok (considering it only has 1.5m head) but the cold water doesn't come through. If I remove the shower head and try to suck the water through (in case of an air lock) I still get virtually no flow and a lot of resistance if the valve is set to below the 38oC point.
Please could anyone suggest further diagnoses, or any ideas at all.
My current thoughts are:
The cold water is not getting through the shower valve - blocked filter or dodgy non return valve?
Antiscald valve is dodgy?
Just to say if the pump does kick in then you get a decent shower!
Many thanks,
Steve
