We have been having a problem with the toilet not holding water. It just drains out slowly. This makes trouble as the water in the toilet is all that is between you and the black tank and all that is in it. I had replaced the Teflon RV Toilet Seal and the plastic ball assembly less than a year ago, so I figured there must be build-up on the seal due to our being in many hard water areas lately. I could have taken pictures of this, but I don’t want to gross anyone out.
This is an old style gravity drop toilet with a foot actuated valve that moves the flush ball aside and also actuates the water fill valve. No electric valve or macerator here. It is a Sea Land Traveler model 110, very popular on older rigs. The entire bowl comes off by loosening one screw that adjusts the tension on a metal band that holds the bowl to the bottom part of the toilet. You also have to remove the flush water line at the back of the bowl assembly. I loosened the screw, removed the 2 plastic guides, and lifted the bowl assembly out and put it in the shower.
Now it’s time to put on rubber gloves for the rest of the procedure. Then I removed the 2 piece seal and took it outside with a bucket of warm water and a scrubby sponge that I tossed after using. Both parts of the seal had lots of calcified material which was easy to remove. About 10 minutes and the seals looked like new. Then I cleaned the top of the ball valve with the sponge and it came very clean in a minute or two.
I put it back together making sure the “This side Up” on the seal was up. Then I placed the newly cleaned bowl assembly back on, centered it on the seal and put the spacers back and tightened the band back up. Make sure to re-insert the flush water line at the back of the bowl, or a small flood will occur. Don’t ask how I know this.
All is well once again and the toilet is holding water again. If you do this and the seal is torn or warn, you will need to replace both parts of the seal. If the ball valve is scratched or gouged, replace it as well. Instructions come with the parts. Get the part numbers of your particular model from your manual, or look up the parts by toilet model number on the PPL Motor homes parts page. They have almost everything you will need. http://www.pplmotorhomes.com/parts/rv-toilet-tanks-plumbing-sanitation-1.htm
