I am also having drains back up. My kitchen sink drain is not draining. when I do laundry all the water comes up through all the tubs shower toliets will overflow. A plumber came out and put a snake through the bathroom sink drain which did nothing except make my pocketbook less 100.00. I have put a snake in the main cleanout may not have been long enough. also ran water with the hose down it and had none come back towards me. the bathroom closest to the clean out will drain eventually. leaving a mess. but the other bathroom seems to not be draining at all. the kitchen sink will not drain. could it be a broken pipe that could cause this?
