: We live in a mobile home in a small park. We have lived here for 15 months. I started noticing drain odor about 6 months ago. Our washer drains out through the main plumbing pipe running under the center of our home. When the washer drains, and I am running water in the kitchen sink, the sink water does not drain, but bubbles back up into sink. After washer is done the sink water goes down. From the kitchen, the washer water goes on through the masterbath and sucks the toliet water down. When we first moved into the home we just heard the water, but did not see these above described events. The smell coming from the drains seems to be strongest after the washer has been used. If the sink gurgles, and for lack of better word "burps", it is awful. Is it possible that the water in the drain traps is being sucked out with the washer water? Thank you.
Juli, It sounds like you have a drain problem and you need to clean your drain lines out. Also you need to look under the trailer to see if the sewer line is connected to the city riser and that it is supported properly.You also may have a bad auto vent at the kit sink (if there is one). I think you should call a drain cleaning company to check these things out for you. Dale's Plumbing Service Inc LMP
