If your Dometic Toilet bowl is not holding water here's a quick video on how to remove, inspect, lubricate, and reinstall it. If it shows signs of damage and does not allow water to hold in the bowl you can simply lubricate and replace it. I hope this video is helpful.
IMPORTANT - USE SILICONE GREASE ONLY - Vaseline or other petroleum products should never be used on rubber or neoprene objects. It can deteriorate the rubber or neoprene very rapidly. The correct lube to use is a silicone based lubricant, which comes with or without Teflon
Last year I replaced our plastic Dometic Toilet with a Dometic 310 Ceramic Toilet (Boy what an improvement it is from the plastic toilet). In the video I mentioned that I replaced it a few months ago, I guess time flew by quicker than I thought because I replaced it a year ago :) Here's a link to that video to watch - • How to Install a 310 D...
Anyway the toilet water started leaking by the flush ball seal so no fresh water would stay in the bowl. In the video you will see me replace the seal and inspect the old seal for damage and show you a couple things that could have been the problem.
One of the tricks is to make sure you lubricate the seal well with Plumbers Silicone Grease and make sure all the surfaces are really clean before installing the seal.
Note: Products I used and links to them are provided below.
