Darren smith Asked :Hi I installed this valve on an unbalanced system Soon it started making a groaning sound and pushing water into the cold water tank I fitted a non return valve on the hot side and now the pressure is down to a dribble ?
Answered By QS Team :
The CTV showers already come with non-return valves fitted. In the exposed they are in the elbows. Remove the extra one you have fitted and investigate the one in the elbow. It may have some debris in it and that could hold it open and also vibrate creating noise.
