Toilet Seal

[DROMEO]

Hey ya, new here and have a 2019 3121RL purchased in May and have only had it home from storage to fix MFG issues (seal, tighten, exercise systems, perform preventative CC). We notice that the toilet (not yet used) will not hold water in the bowl. Done my research, and it really sounds like replacing the toilet is the fix. Should not be on a brand new unit. Being an Aerospace industry (engineer) my mind races with possible fixes. I will say this (working CE/ATEX, Haz Chem), veg oil, vasiline, or other similar lube may cause damage to the chemical structure of the seal. Veg oil, not so sure, but definitely the patrolium based lubes... The Veg oil may promote the growth of mildew and thus further causing the seal to leak. Only fix I have found is to continually wipe the seal dry after each flush. Note - toilet has not yet been used for its intended purpose - Filled it up last weekend and will be going back to check. 100% positive there will be no water in the bowl. DW thinks I’m crazy for wanting to replace it with a Dometic 320. Anyone wanna buy my never used toilet? Thanks for reading

You can get the Dometic 320 with sprayer at PPL. I paid 199.00 and free shipping. I threw out what seemed like a perfectly good toilet before i had problems. As we have all noticed you don't have any problems with the rv parked in the driveway.

I just checked prices at PPL and the 320 bone finish with spray is 200.99 with free shipping. The white 320 with spray is 179.99 plus 9.99 shipping. Both toilets have standard height which is what most people have in there rv's. I doubt you will find a cheaper price any where.

That’s good to know, I’ll look it up. We do have the tall toilet which I’d like to keep the same tall in the Dometric.

Come on Carl ! This calls for a YouTube video demonstration!
“Hello fellow Montana Owners. Today I will demonstrate removing the seal from a dometic 320 RV toilet and cleanin’ da junk from da bottom side! First get your plastic gloves and prepare to smell things up in the RV for a bit.” Etc. and so forth. Can’t wait to see it!

Ask and ye shall receive.

Clicky

Note the valve is only open long enough to grasp the seal and pull it out. Replace it with ball closed to avoid dropping it somewhere bad.
