Check the vent pipe on the roof of the RV. The vent pipe should extend above the RV at least two inches, and it should have a tight seal between the roof and the pipe. If the pipe is too short, replace it with a longer pipe. Seal any gaps between the roof and vent pipe with caulk.
Check that there are no blocks in the vent using a flashlight. The vent should be clear of all obstructions. Remove any obstructions from the vent if necessary. Check for any leaks in the pipes or around the toilet. If leaks exist, seal them with caulk.
