Smell in bedroom from closet

[rogernsuzy]

When we bought our FR3 30ds we noticed a horrible smell in the front closet of the bedroom. We took it to the dealer, who spent a month fixing it. But the smell is back.
Has anyone else had this problem?

What kind of smell? Is the sink next to the closet?

[rogernsuzy]

They didn't succeed in fixing the smell. It is in the closet closest to the toilet and in the drawers below the closet.

[rogernsuzy]

They said they sealed the black and grey tanks and the vents coming from them.

Look under the sink and see if you have a short vent with a valve and cap on it. the smells can move around.

I'm not familiar with the layout of your MH, but if the vent stack from the black tank has been punctured during manufacture or when/if modifications were done where it goes past the closet area that could cause some bad smells to escape into the RV.

Oftentimes it's one of your air admittance valves like cavie mentioned above. In my experience the gray smells even worse than the black. You probably have two or three of them in your rig. Here's a few photos of mine. The stock valve just screws off the PCV pipe although sometimes they get stuck. I had to drill a hole in mine and turn it out with a screwdriver. You can pick up cheap replacements at Home Depot although I recommend you buy the more expensive ones (Studor) and you'll likely never have the problem again.


Not sure if these photos will display. I just uploaded them to a google photo page. The first two show the original valves and the third shows the Studor replacements.

Thanks! I'm just a little confused as to where on the coach this picture was taken. Was it behind the closet? Does the closet come out?

Sorry. I should have noted that the photos are not from an FR3. My brother has one so I like to look in on this forum and see what 's going on with them. Nevertheless, you must have at least two of the air admittance valves in your coach. On my coach, for example, there are two under the closet (black and washer) and one under the kitchen sink. The closet ones are well hidden and hard to get at. It's a mystery why manufacturers insist on hiding these things. Anyhow, when they don't operate properly the smell is awful. If your valves are good you should never have to add anything to the black tank. Good luck and sorry again for the confusion.

Could be water in the wall from a leak from the roof.

Oh!, now I know where I left my socks.

So, is it a sewer smell? Skunky smell, mold? Ammonia?

[RV Pilot]

I’ve never had any smells. FYI

[alexchuang]

So I was out camping and I noticed a horrible smell coming from my kitchen area. My Black was probably about 2/3 full and we were just about to get going out of the campsite. The smell came from the tank vent pipe down into the vent cover right next to the sink. I think I need to install one of those tank vent vanes.

[rogernsuzy]

While flushing the black water tank I heard a noise from the toilet. When I flushed the toilet a stream of air and water shot out. Apparently the vent is clogged and the entry of water caused a pressure build up.

Does this make sense? Should I try pouring water down the vent to see if it is stopped? Maybe snake out the vent?

Try draining your water lines to the washer, if you don’t have a washer. Mine started smelling but after flushing both lines,the smell went away. Now I only smell my MIL if she comes into the trailer.
