About Dana Bostick
Expertise
Pretty much any residential plumbing questions. Note: I live and work in Southern California. We do not as a rule use boilers, hot water or steam heating systems or wells so my knowledge in those areas is limited. There are others here that can probably answer those questions better. "We all is city folk" out here! What is a "well" LOL

Plumbing in the Home - Mobile Home sewer odor


Expert: Dana Bostick - 11/10/2009

Question
1)My son and his wife live in a single unit mobile home with one bathroom. The unit was brand new and never lived in with built in stove, dishwasher when they moved in. Immediately after using the dishwasher my daughter in law noticed a very foul smell and murky water settled in side near the drain after a day or so from being used. She constantly is turning on a wash cycle to clear the smell but it returns. The dishwasher sits next to kitchen sink- what I've noticed is that like at my home there is no opening/vent next to sink faucets where soap my seep out.
2)They have a washer and dryer about 30-35 feet away fron kitchen sink and they also have a very bad fishy odor that comes from the washer. They don't have any back up or odor from the bathroom area.  What could this problem be?  

Answer
Hi Stella,

Here are a few possibilities:
That "opening next to the faucet where soap seeps out" is called an air gap and it is required by most codes. Its purpose is to prevent exactly what seems to be happening, the backup of sewage into the dishwasher. One should be installed.  The dishwasher needs to be sanitized before using it as well.  It is now contaminated and unsafe. You should have an air gap too!

Possibly the dishwasher pump is not working or is blocked by something causing to not empty completely.

I would have the incoming water tested for contaminants. Many parks are on well systems as well as septics and the water table may have become fouled.

Another thing to check on the washer is if there is a trap on the drain line. Without one, you will get sewer gases coming back into the area when any drain is used.  Even if it does have a trap, if the washer drain is not properly vented it will break the trap seal and allow the gas to enter too.
Good Luck,
Dana
