Remove the RV toilet
If this is a problem with the seal on the floor flange itself, it should be possible to remove the toilet in order to determine what is wrong.
Steps for removing the toilet are as follows:
- Draining and rinsing black tanks are recommended.
- Prepare a location for the toilet when it is removed. Prepare a location for the toilet when it is removed. If it’s in an RV, protect surfaces with cardboard or old towels.
- You should turn off the water pump or the city water. By flushing the toilet, you can relieve any remaining water pressure.
- Remove the freshwater line from behind the toilet. A small mirror can be useful for this step.
- Remove the two bolts at the base of the toilet. After removing the flange bolts, place the toilet in its prepared location.
Inspect the floor flange carefully
The floor flange may crack, warp, or be mounted and screwed/glued incorrectly. Any of these problems should be taken to an RV repair facility.
If the flange looks fine, the gasket is most likely the culprit. If the floor flange is damaged, the gasket should be replaced when the toilet is removed from it. For RV toilets, you will need a foam gasket instead of wax rings like on residential toilets, so be sure to get the right type of gasket. A gasket can be ordered from Amazon or picked up at an RV dealer. Mount the gasket on the toilet base, not the floor flange.
Install your RV toilet again
- Before slowly lowering the toilet, align the mounting holes with the T-bolts.
- Resecure the toilet by installing the nuts on the floor flange. An over tightened nut could damage the toilet. Sit on the toilet without wobbling it. If necessary, tighten even more.
- Freshwater fittings should not be overtightened or cross threaded.
- If you have turned off and flushed the water, check for leaks.
The leaky RV toilet should be fixed after this.
