Bragged last week that I had fixed the blade seal on the Thetford. NOT! I searched this forum and tried all your "fixes" to make the Thetford hold its water.

Guess I'm down now to replacing the seal. Looked up instructions and it doesn't seem too hard. How many of you have replaced your own? Any tips or tricks to relate?

I removed the seal on my Aqua Magic V, cleaned it and put it back in. I think the IV is similar. There were mineral deposits on the seal that I scraped off and the seal has been good for 2 years now, held the pink stuff all winter.

Its kind of a messy job but not difficult. Remove the toilet, take it outside and give it a good hosing someplace you don't mind leaving a small mess. Think of it as fertilizing the grass. The seal came out easily and went back in easily.

Hope you are not squeamish.

A nose pin and long rubber gloves will be invaluable.

Same issue. I thought I had it once, but alas, no. Bought a new mechanism for it but was waiting until we got home to put it in. Long story short, decided to give the cleaning one more try. Got in to the grove with a bent coat hanger and scraped out a whole bunch of calcium and crude. Flushed it out and put in a large quantity of plumbers grease. It has worked flawlessly ever since. Got a mechanism if someone needs.

My SeaLand came with one of those disposable ladies finger nail files. The type with a sand paper like substance on both sides. The directions said to use this thing to clean the seal if it leaks. It does a great job and I still have good water retention after 8 years. I also make a special effort to clean the underside of the seal with toilet bowl cleaner when ever I'm performing that duty.

If you do proceed with replacement vs giving it another cleaning.......

I found it a lot easier to remove the whole toilet and take it outside, clean it thoroughly and then disassemble.

More room to work and you can really clean it up. But you should also get a new floor flange seal.
