Toilet issue

My toilet, a Dometic 320, has suddenly started acting like there's a vapor lock when I flush it. I step on the pedal and it burps and sometimes even burps so bad it splashes some on the floor. What is causing this? Thought it might be a full tank so I emptied it but it didn't help. Any ideas?

Sounds like some brute force is warranted to get it out. What do you mean by a "tank cleaner thing"? Is that a flush wand?

Well, it's the pyramid. Vent was clear all the way into the tank. Got a friend to come over and try to clear the poo pile. Pushed through it with a tank cleaner thing on the water hose and got it cleared. New problem is the tank cleaner thing is now caught (they pushed it all the way into the tank) and can't get it back out! No idea what to do now.

from hussbuss. Had the same problem with our cruisers Enterra. Found out the bee's had plugged the vent pipe solid. We just purchased this trailer after it sat on the dealers lot for a year. The dealer added a piece of screen under the vent cap to discourage the bee's.

We had a pyramid, and dealer had me use U Digest it. We put in a quart, and it soon took care of it. Today we use U Disest it on a regular basis. No more poop build up.

As mentioned in op, I had the tank emptied when it first started and I don't leave the valve open. I have someone coming to check out the vent and/or the pyramid. Praying it's the vent! Thanks for all the suggestions. Will report back with solution.


I'd rather have the Death Pile than a loose vent. Easier, though messier, fix. ๐Ÿ™‚

Ours did this. Our toilet doesn't drop right into the tank, there is a pipe over to the tank. My wife wasn't flushing enough water, and it partially plugged in the tube. I now carry a six foot hand toilet snake in the trailer. I don't need it often, but when I do, I'm glad to have it.

Does yours go into a pipe?

Just a guess...have you been leaving your black tank dump valve open while camping?

As Rhagfo suggests, you have developed a pile of poo and tp at the bottom of the pipe. This normally happens because folks flush the toilet without using enough water. You'll need to physically bust up the pyramid. One way to do that is to stick a water hose down the open toilet and flush away the pile. Once clear, make sure you use enough water whenever there are any solids being flushed.


Yep X2


X3!! Or you need to dump your tank!

Air has to escape in order for stuff to go into tank
If vent line is obstructed then air has to escape up thru toilet line hence the 'burp' and splash when you flush

Go upon roof....remove black tank vent cap
See if top of vent line is level with roof line OR has it dropped down ?

If dropped down vent line may be sitting on bottom of tank


If level with roof line.....run a garden hose down vent and blast water thru........tank drain valve open so you know water is flowing thru vent
Is it time for your medication or mine?
