Ok here is my problem. I live in an older mobile home and have been having some plumbing problems recently. When I run the washing machine or shower sewage backs up into the shower until I turn whatever I'm running off while it goes back down the drain and also water spills out all over the floor from the toilet. Water also backs up into all the sinks. So basically I have water everywhere. The biggest problem is it spilling out all over the floor from the toilet and it sitting in the shower. Any help would be much appreciated!

you have a blockage in the main. Snake the line from the lavatory vent pipe on the roof. good luck, Tom
