Seals have failed and bowl will not hold water. Original seals have a black rubber and white teflon seal combination. These seals are no longer available. Replacement seals currently said to work DO NOT. I have bought and tried both available bowl seal kits and the will hold water in bowl but they both weap water on the floor after flushing. They not only do this for me but also the licensed RV Tech I had come on site for help. Ball is clean and not damaged. Sealand says there is no problem with the new seals and dometic acknowledges there is a problem with the new seals. For some reason they have discontinued making the original bowl seal kit with white teflon seal. That kit is the ONLY one that will not weap water onto the floor after a flush. After having the toilet apart 8 times using different combinations I finally am able to hold water in bowl sometimes and not dump water on the floor by combining the blue seal from the new kits with both top and bottom of old seal kit. I have now a 3 piece seal kit until I get help for the correct repair. This allows me to hold water in the bowl long enough to enjoy its intended use. Is there someone out there who can help me? Thanks usmade56@yahoo.com

This is follow up. I have replaced the toilet with a thedford model. I am happy, working as it should.

usmade56,

Do you still have the Thetford part #?

The seal in my 210 is quickly becoming incontinent. I saw that the original seal has been discontinued and was preparing to buy the replacement. Glad I saw your post!

Thanks,
Steve

For others with problem holding water in bowl. I had slow leak and read manual. Instructions say to let it SNAP back. Once I started sliding foot off pedal, no more slow leak.

I replaced the sealand toilet with a thetford aqua-majic style ll china bowl pedal flush toilet. My paperwork does not provide a part number. I haven't used it much since installation but I can tell you it has a much more robust flush. The toilet doesn't have the clean up hose and because the flush is so much better, it doesn't need it. The thedford bowl seal kits I have seen in RV stores are much more robust looking than what Sealand offers. My first impression, thetford is a much better unit.

Very true. My Sealand leaked at the two year mark. I did not replace the seal just cleaned it up and began following instructions to let the valve snap back. Toilet is now 8 years old with original seal. Still holds water fine.

Is the leak being described a leak from the bowl into the black tank or from the bowl onto the floor? Ours slowly leaks from the bowl into the blank tank.

I am considering adding a riser to my Sealand 210, but if adequate floor seals are not available, I may reconsider. And I'm not sure the readily Thetford riser will fit the 210. I see references to the 510, but not to the 210.
