Sewer Smell

Question: We have a 2000 Gulf Stream Palm Breeze. When the wind blows a certain way we get a horrible sewer smell in the storage compartments of our coach. It permeates the inside of the coach. We have changed the valves under both sinks and have check the vent on the roof. We seem to only get this smell when the wind blows. Help please.

Answer: A difficult thing to figure out, but we will venture a guess that perhaps there is a break in one of your vent pipes that run from the black or grew water tank up to the roof. If there is a break anywhere along the pipe that could cause the leakage of sewer gasses up into the interior of your RV.

Another possible source are your p-traps, so make sure that you clean them out periodically; use any biodegradable enzyme to break down bacteria and solids . Also, try to keep the p-traps full of water while moving and when stationary. We also recommend that you keep your dump valves closed to further prevent sewer gasses from entering through the dump valves while connected to a sewer connection.

If anyone has any further thoughts on this please provide input.

Sewer Smell

We just took off for the first time in our motorhome up to Duncan Mills. When I was unpacking from the back compartment I kept smelling a sewer smell. I did not say anything to my husband because it was slight. 2 days later I was positive
we had a sewer leak. It was getting stronger. I finally broke the news to my husband and we tried to find the source.where It was getting stronger but could not locate where it was coming from.The smell was everywhere.I finally figured out what the smell was when I went to cook dinner. First time trying to light the stove unsuccessfully I realized where it was coming from. Propane smells like rotten eggs. They had overfilled our propane tank.

We had that and it turned out to be old water in the washing machine. We ran the washer and the smell left. Now we run the washer every month.
