Hi,
I have a Potterton Performa 28 combi boiler and a gainsborough mixer shower.
The problem I have is the water temperature changes from hot to cold then back to hot.
I had the same problem with a gainsborough thermostatic shower and changed it because I was told the problem was with the shower not the boiler.
We have a service contract with British Gas and it was one of their plumbers who told me to do this after he had checked the boiler.
The boiler is apparently running as it should so no problem there but how do I get over the temperature problem - do I need to fit a pressure reducing valve on the cold water supply to the shower?
Any help would be greatly appreciated.
Thanks
Brian
