Does your RV toilet hold water? Typical gravity-flush RV toilets require water at the bottom of the bowl to seal against black tank odors from coming up into the living area. After 20 years of full-time RVing, our switch to part-timing meant getting used to some changes. One thing we hadn't considered was that RV toilet seals are more likely to dry out when not used regularly. So our toilet seal began to leak over time while our rig was in storage.
Following the instructions in our Dometic RV toilet owner's manual, we used the trick shown here to solve the problem in minutes. If your toilet seal is leaking and allowing the water to drain out, try this tip before spending money or effort replacing it. It's quick, easy, FREE, and it really works!
