I have a shower mixer that is above the water level in our cold water tank. This is in a loft conversion. Cold water is fed to to a twin booster pump fitted below the cold water tank. The hot water is fed to the booster pump from a point at the top of the hot water tank through a special flange. This flange is fitted above the inlet to booster pump.
When in operation the shower water rapidly runs cold (2-3 minutes) and the hot water pipes from the pump also go cold. The thermostatic shower mixer valve has been replaced without change.
Any ideas?
