[norwoodt]

ive just had a msg from a customer, who's overflow rom there HW storage tank is leaking.

hes had a look and said its not the ball valve, but he can feel water coming in from one of the oulets, if memory seves me there is at least two oulets as thee is a shower pump.

cant go look at it till tomorrow, but was wandering if anyone had any thoughts?
