Plumbing Question!
I have a single lever shower. The hot water comes out on the cold side, and the cold water come out on the hot side. How can I find a remady to fix this situation. I don't want to have to repipe the lines , unless it is necessary. Thanks for any advice.

If you have a Moen faucet there is a easy repair. Remove the handle and simply reverse the stem, There should be a mark ion the stem. This mark goes up. If you have another brand I have to know what it is before I can help. Good luck, Tom
