What the %^&% is that stench?

[tyler811]

Ohhhh wait I found it.

[tyler811]

Got it, is there a way to test thing?

[Bama Rambler]

It's pretty common for those to fail. The best thing to do is just replace it. You'll also wind up with a better quality unit as well.

Went to Menards and Home Depot but neither place had it. HD wanted me to rig a contraption going to 3 inch pipe and crap. I told him it's a simple screw on AAV and I was not going to a five second project and turn it into a half day marathon. I ordered it off Amazon and let you know if it works. I also do have a Dometic 300 series toilet [emoji51]

[Bama Rambler]

We're lucky that our HD carries them in stock.

Call Dometic as mentioned above and see if yours is one of the affected models.

If you put a quart of water in the toilet, will it stay in the bowl? I ask because my friend had.... Basically dried poop preventing the toilet from sealing all the way closed. Fumes were coming through the flush flapper.

Yes Sir, it does though I am doing a guesstament based on what I see. I not have nor do I intend to take ruler measure the water depth.

Where is your sense of adventure??
It was a shot in the dark. Pun intended

Shake it. If it rattles it should be good to go

The vent, if facing the rear, will create a vacuum and draw air out of the trailer when you are moving. What I found on mine was where the fill came through the floor was just in back of the toilet. The hole was quite a bit bigger than the hose. Also where the bathroom floor was against the outer wall there was a small gap. Sitting still the smell went away when traveling it got worse. So I sealed the hole where the hose was and the space between the bath floor and outer wall. Solved the problem.

I am sure the vent was pulling air through these openings causing the problem.

After three days of smelling nothing, my wife insisted I place my chest on our Dometic toilet earlier this year and take a deep breath. We replaced our model 300 toilet post haste. Thank you Dometic for the outstanding warranty response. New model 300- end of problem and it was a problem.

I installed it and and we went a long weekend trip. After a day or so it really started to smell inside the trailer in the bathroom.

At first I thought an animal made a hole in the black cover underneath and crawled up there and died. But you only smell it from the inside. So when we left I emptied the tank and eventual the smell went away.

We left for another trip and again after a day or so the smell came back. While on the trip I bought one of these but that did not help as smell was still there


Could I have bent a pipe while on the roof. Toilet is your basic Dometic with the foot peddle flush.



UPDATE:

TT 2018 Forest River Salem Ultra Lite
Also I did not touch the pipes, could I pushed the pipe down just being on the roof?

tyler811;
Did you install the new cover facing the sewer roof vent? Perhaps it is drafting down into the new cover and into the roof vent in the bathroom if you are leaving the vent open.

Do you have an exhaust fan in the roof vent that you run while flushing the toilet? If so, it will suck the fragrance out the BT and into the bathroom. You need to make sure the exhaust fan is off before you flush. Don't ask me how the DW found this out! LOL.

If you have external access to your BT, you may want to consider adding a BTFlush. I added a Camco Tornado to both the BT and GT on my rig. No odors and no more wand down the toilet to clean the BT, and so stinky sink syndrome from decaying food particles in the GT. The install takes about 30 minutes each.

I hope this gives you some ideas to resolve your stinky issue.

Good Camping .... Swampy

But if you shake it more then 3 times your just playing with it.

Use TankTechsRx treatment in the black and gray tanks. I had the same problem and this resolved it. It's probably not the "hardware", more than likely the "software".

TankTech is expensive at $39.95! Some folks have had good success with Rid-X, other OxyClean powered which is an enzyme treatment.

The reply about the Dometic warranty issue was my problem when I had similar symptoms on our 2018. I am going to include some pics.

The 2 halves of the unit are sealed with a type of square o-ring (also known in industry as a quad ring). The ring was rolled as the 2 halves were slid together causing a leak.

Using mirror I was able to look into the back of the toilet and see that urine had leaked out of the bowl into the outer portion of the lower half.

Dometic sent me a new toilet very quickly, but my unit was successfully reassembled correctly and hasn't leaked since.

I've carried 2-5 gal Jerry cans with me from the days of my 1st rv, now on #5. Use both bff and flush king, takes about 10 min to complete process. What really works crazy good if you have time either at fhu site or end of season is to pour contents of Jerry cans through toilet and hit pedal as rapidly as possible. If you have clear elbow on your dump valve and a spotter to observe, you'll get the idea!

Reading this post, do you use your shower much?
I noticed that same bad smell issue one day with our 15’ camper. The shower had never been used for a very long time. So I put a quart of water down the tub drain. Smell gone, now that water is in the p-trap. Secondly, I use a different approach to keeping the black/and gray tank smelling it’s best by using a Commercial product that we use at work, used it for 10 yrs, called Betco Green Earth drain Push cleaner, a (true) enzyme that works extremely well to break down and in eliminating waste odors. Safe to use, and I like it better than the other products on the market for black tank treatments. This stuff is really awesome. Comes in gallons, but after you do the math is not too expensive per quart. Only need a few once’s to start getting the enzyme to do its job.
How this help’s.

[sherman12]

Trimman, Betco looks interesting. I bookmarked the link to it for future consideration. Thanks!

[Trimman]

The Betco product can be used on any sewer, septic systems , safely anything where organic matter needs to be cleaned up. I even used it to save a refrigerator that had lost power for days, removed all the bad stuff, cleaned with chlorine, then used the enzyme to remove the rest of the organic matter and smells. There’s a guy on eBay that has a 4 gallon Betco green earth drain push for about $35. that’s a bargain.
I buy it on Amazon for $87. / 4 gallons, but well worth it !!!
