Sewer Smell in bathroom - Page 2

No one has mentioned exhaust fans. If you turn on an exhaust fan and do not crack open a window, air has to come from somewhere. If a window isn't cracked open, it's going to come from your holding tanks, especially when you flush the toilet. As suggested in real hot weather, add more chemical.

vent pipe to far (deep) into black tank, once the water is past the bottom of the pipe fumes have nowhere to go but back thru flush valve

When I took the cap off the black water vent on the roof there was no chalking around the vent pipe and sewer gas was coming up the inside of the pipe and going down the outside into the RV. Caulked around the vent pipe and smell is gone. Hope this helps.

The same problem that Dometic had with the 300 series also occurs in the 310 series. I had to replace my Dometic 310 under warranty for the same problem.

Mind if i ask why you don't use your shower? It's good for the 2nd/3rd drain.

Using the fan?

mike.t · 08-09-2015, 09:28 AM

A good bathroom fan will pull odors up while using the Ferguson.

Not running the exhaust fan. Removed toilet yesterday and there is no odor coming from "toilet hole". Odor seems to be coming from toilet itself, but i cannot see any buildup or anything. Vent piope and drain pipe in storage area look good. I never had a problem like this with my old, cheap Onyx. I know there were problems with the Dometic 300, but has there been any problems with the 310 that replaced it?

So.... if you are not getting any aroma from the black water tank by itself and you are getting it from the toilet when the toilet is removed... like in your garage while working on it ... then where would the order be coming from

is there something left over in the toilet because there shouldn't be a disconnect and a continual stench present if its no where near the black water tank.
especially if you have done all the things you suggested earlier.

I wasn't getting any odor from the black tank either. But the toilet stunk up the entire camper. I carefully removed the toilet without tipping it, brought it to a dump station and then turned it over. About a half a gallon of raw sewage dumped out of a void area on the rear of the toilet. I replaced the toilet and have had no odor whatsoever in the camper ever again.

Don't know why one wouldn't use the toilet and shower. Once in a while we might use the campground shower but it is so convenient to have the full bathroom right there. I can't imagine using the bathrooms in the middle of the night in the campground, especially if not real close.

dmac1951 · 08-10-2015, 11:09 AM

Larry, i believe you are correct. Cut the under belly and do not have a problem there. Connection, pipes, etc. all look good. Black tank vent is not stopped up--ran water down through vent out of tank dunp valve. I separated toilet bowl from base and got the same odor, but did not see any liquid. I did see a very small anount of buildup in a few nplaces. Sent Dometic an email this AM but no rersponse yet. Thinking about replacing all seals and gaskets. This is not what i wanted to be doing today!

dmac1951 · 08-10-2015, 11:38 AM

well, i just found out about Dometic customer service big time. Lady told me to take it to a service center. I told her that i had already remove toilet from rv and it smelled. She said we do not have a problem with our toilets and that was that. She did wish me a happy day. Guess i am now on my own!

Summer2Go · 08-10-2015, 02:53 PM

I'm wondering if I am using an inaffective chemical. I have little green pillows.... I forget the brand name. Our first trailer with a bathroom, and their are stinky smells. We have to do something different...

Your experience with Dometic regarding your toilet leak is totally opposite the experience I had.

In April of this year I had the leak/seal problem with my Dometic 310. I placed a call to Diane at Dometic and she sent me a new 310 via overnight shipping at no charge. The entire transaction didn't take 10 minutes!

Here is the contact info:

Dometic 800-321-9886
diane.staman@dometic.com
Heidi.mcclain@dometic.com

I hope you get some satisfaction. My experience with dometic was fantastic!

larrys2112 · 08-10-2015, 03:58 PM

Diane overnighted mine as well at no charge.

dmac1951 · 08-10-2015, 08:27 PM

Thanks for the info. I will try again tomorrow.

mike.t · 08-10-2015, 08:48 PM

They sent out a new 310 overnight free of charge and did not want the old one back?
Well it shows(my thought) how cheap these are. No wonder they have problems.
Update.I'm fast.

Do you have a P trap under your bathroom sink?
If not you may have a Hepvo valve as my trailer did.
They can get loaded up with hair and soap scum and either stick
open or plug up completely. If it sticks open and you leave your Gray water
dump valve open while hooked up to the campground sewer system, odors will
work their way through your drain system and come out your sink and shower drains.

dmac1951 · 08-11-2015, 08:53 AM

Yes on p-trap. Just talked to Diane at Dometic. Much nicer than last person I talked to. No help will be coming because I am not the original owner and toilet is over two years old. I am going to reassemble toilet using sealant on gaskets, a new flange seal, and hope for the best. If problem arises again a new toilet hopefully will be the answer. Thanks for all of the replies.
