trapped air?

tomnjanAugust 8, 2010

I have a single story house with a full basement and sewer under the basement floor. The bathtub on the main floor will back up for a period and then drains faster than the water entering the tub. I suspect that somehow air is entrapped in the system and once enough head pressure is achieved, the system seems to "burp", and flows fine. Any thoughts or known remedies?
