Hi.
I have a problem: Cold water back up into hot water pipe. I think there might be something wrong with a shower valve since water out of a shower comes out barely warm. And even when the shower is off the cold water goes back into hot water pipe and again barely warm water comes out of hot water facet in nearby sink.
Question: any ideas why is this happening and how to deal with it?
The shower maker is unknown/could not find it, but it looks 5-6 years old (definitely not older) and it's a single handle shower with no tab.
Thank you.
