Hi there
I recently had a problem with backfeeding of cold water in the hot water tubes, I have an unvented direct cylinder. We tried all mixers but apparently the issue was caused by the valve visible on the pic attached. We closed the valve and all seems to be working. The plumber is not sure what that valve is and my neighbors don't know either.. what could it be? Thanks
