I installed a thermostatic shower as a replacement mixer shower about a month ago. Recently it has started acting up with only the cold coming through and the shower stopping all together if it is turned all the way to hot. I think it has something to do with the hot water not getting past the in build non return Vv. It may be to do with the water pressure differential but it isn't that great as the cold is gravity fed from the cold water tank in the loft and the hot is from the Tank (also gravity fed from the loft). Can any one help as my wife is getting fed up with going downstairs for a shower, cos it has no heating and a non opaque window which our neighbour can look in to?!?
Many thanks J
