What is wrong in a house built in 2000 if the toilet and sink bubble when taking a shower and the tub will not completely drain for 20 minutes?

Answer 1

I had a similar problem recently, though our house is about 30 years older. In our case, the problem was blockage in the main drain line from the house. You should have at least one clean-out somewhere between your house and the main sewer line. I would unscrew the cap and look in the pipe, maybe even have someone flush as I watched. You should see water flow past. If you see water in the pipe when you unscrew the cap, there is a blockage somewhere between there and the main line. If you don't see a rapid "whoosh" of water going by as a toilet is flushed, but see a slow steady flow, you probably have some partial blockage between there and the toilet. In either event, a good main line "snaking" should solve the problem.
