Thank you for your question. Delta Faucet model # 635-C is a lever handle tub and shower. Unfortunately, the only thing you can do to fix the line reversal is to go into the wall and change the supply lines. This faucet is now discontinued so we are not sure that we would recommend doing that. If something happens and you need parts, you may not be able to get them.
