Tecma Fix

go-rv'r, I see you are on this forum too. For anyone who is interested in this issue, that is my post on irv2 and the fix suggested by go-rv'r. Fix was easy. Winnebago paid for the fix less the $45 service call.

The link below has a solution that seems to works.

There is also the classic problem where the toilet knife valve is not making a good seal. Needs silicone spray and a good scrubbing itself and around where it goes into.

This is a MACERATOR Toilet. There is NO knife valve. Doug

The Toilet has a 2 year warranty. Does the water drain out while camped or while driving? On the back of the toilet, you will see a "Y" hose that is connected to the 2 fill/flush nozzles. Then you will see the LARGE 1.5 inch discharge hose (the J loop). The TOP of that loop MUST be even with the flush nozzles. If NOT, then you have the siphon effect draining the toilet bowl. Look at the link. pics I-1 and I-2 are not correct for your install. Figure A is close. Look at item 6 page 10 to see how high that hose should be. Doug

Thanks! You've been more helpful than Thetford. I think Winnebago didn't install correctly. Will pull stool and check diagram.
