Where Do RV Toilets Clog?
RV toilets are most likely to occur in one of four locations.
Some clogs occur right at the blade valve located at the bottom of the toilet bowl. The cause of this is generally either too much “stuff” (solid waste and toilet paper) sitting in the bowl itself, or too little water in the bowl before that “stuff” was added.
An RV toilet may also be clogged in the pipe or tube that leads the toilet contents from the toilet down into the black tank. The cause of a clog in this location is likely similar to a clog at the blade valve – too much “stuff” and/or too little water!
Black Tank Inlet
A clog may be located at the outlet/inlet to the black tank itself. In other words, just before the waste and paper exit the pipe/tube and drop into the black tank.
A clogged RV toilet can also be caused by a backed-up black tank. If your black tank overflows, you’ll have a clogged toilet because the waste won’t be able to descend into the (full) black tank.
An overflowing black tank is generally caused by either not dumping your black tank in time or not dumping it completely.
If you’re relying on your RV holding tank sensors to tell you when to empty your black tank, you’ll want to make sure that they’re working properly.
Now, tank sensors are notorious for delivering false information. But one thing you can do to help is to clean your RV tank sensors.
And no matter how meticulous you are about keeping your RV sensors clean, if you’ve been using your RV for years, you’ve very likely got a build-up of struvite (which can prevent tank sensors from reading correctly), requiring a power-washing of your black and gray tanks.
What Causes RV Toilet Clogs?
The answer to this question depends to some degree on the location of the clog. But there are a number of things that can lead to an RV toilet clog.
Too Much “Stuff”
As we noted above, excessive “stuff” in the bowl can cause a clog at the blade valve (where the toilet opens to drop the contents below).
The same thing can occur (for the same reason) when you flush the toilet and too much “stuff” enters the pipe/tube that leads to the black tank. The waste & paper can get stuck in that tube, unable to drop into the black tank.
An RV toilet clog can also occur when waste and paper build up inside the tank itself. When this occurs, (and it’s very common), it’s generally because the waste and toilet paper aren’t able to break down sufficiently in the tank.
In fact, if you’re not using any product to help break down waste, this is a likely culprit of your RV toilet clog.
