Hi
Hoping someone here can help me out, here's the problem
We have a mixer shower fed by cold mains pressure water ( no cold tank ) and the hot water was fed from a shower pump (Bristan Single Impeller Pump). Hot water tank has a cold water header tank and two immersion heaters (no gas in property).
It was working fine until the pump packed up so I changed it with a Salamander CT55, now when you turn the shower to full hot it works fine but has you reduce the temperature to allow more cold through the pump cuts off only allowing cold water through, so it can only be boiling hot or freezing cold.
Would anyone have any suggestions on how to cure this problem?
Many thanks in advance
