I had a small leak in my hot water/central heating system. Can anyone help my identify the problem part? It is a 'valve' on a pipe behind the water pump. It has a clear cap with a red indicator underneath. The plastic cap has begun to perish and hot water was spraying from the seal. I have turned the hot water and central heating off and the leak has stopped.
Hi stuntdog23, Without seeing how the valve is installed in the pipe work it is difficult to positively identify it but I guess it is a thermal balancing valve. Regards S
