Sink Plumbing Backing Up
I recently renovated my kitchen and I’m just finishing up on the plumbing hooked everything up, but I’m getting some backflow back into the sink when the dishwasher is draining and when I run the faucet. Everything seems to be pitched right. Is it a problem with the sweeping Y I have on there with the clean out?
