Yes Mark, you are 100% correct according to Thetford. I asked and they OK'ed a product called "Super Lube" I get from ACE Hardware. it contains Syncolon which does not deteriorate the rubber seals. They also suggest Silicone Spray which I use monthly to stay on top of the situation. I recently replaced the Blade Mechanism and Blade Seal in my #19430 Aria Deluxe. The guy above asking about the noise his unit makes…..It's the old motor in his Mechanism. Mine did the same….when I replaced the Blade Mechanism, that loud NASCAR sound went away. It's such a lot of hassle working on these that I try to stay ahead of the problems and keep everything lubricated to prevent problems from slipping up on me.
Floor Covering Replacement & your Toilet…something you will surly need to know….
I had to replace the ceramic tile floors in our 2003 40' Holiday Rambler "Imperial" and used 1/2" thick Engineered/Laminated "soild" wood flooring. This raised the floor level just enough to prevent the Rubber Flange/Floor Seal from getting the proper compression needed to prevent leaks. If anyone out there is thinking of the same type of Flooring project….Be sure to measure from the top of your existing Flange located in the floor, not the toilet, to the top of the tile you are replacing. When the new flooring is installed, take a new measurement in the exact same way. The difference in the two measurements will give you the thickness of the spacer you will need to use to be sure you have good compression on the existing Flange/Floor Seal. I wish someone had alerted me to this issue ahead of time…..So, since that didn't happen….I'm sharing it with all of you now.
The floor flange is screwed to the wood sub floor. If you can remove these screws and turn/screw the flange to the right a few turns, it will adjust to a taller measurement and you will not need a spacer. But, they use a LOT of Butyl Caulk under the flange at the factory. This can be near impossible to break loose after several years. It was for me at least. I opted for the spacers…..
This is a problem that Thetford had no ready made answers to. It is a real issue you Will face, but never hear it spoken of until you are mounting your toilet onto the new flooring. The added thickness of the new flooring material takes away from the height of the existing floor flange which reduces compression on the seal…thereby allowing water to pass around the seal. I hope this prevents some of you from learning this the hard way or having to pay a Tech several hundred $ for a 15 minuet job that you could do yourself…. After all of this, I've become sort of a 1/2 expert, lol… So, feel free to contact me if I can help you somehow……firstname.lastname@example.org
Best of Luck to All
