Hi,
I thought I originally had a boiler problem but turned out my Bristan Calico bar mixer shower valve is passing cold water into the hot water circuit.
I phoned Bristan to ask about this and the guy on customer support told me that the non-return valve on the hot side of the mixer must be either faulty or stuck open. He advise me to remove the valve and have a look.
I have removed the valve and stripped everything I can see out of the body but can't see what I would think to be a non-return valve....anyone know where this is likely to be or what it is likely to look like ?
Cheers
