I agree with Old-Biscuit, but I’ve used vegetable oil to rejuvenate a seal that leaked. Additionally I recommend putting an inch of vegetable oil in the toilet to keep the seal in good condition if you store for a while. It will keep the seal lubricated, and it won’t evaporate.


I use Olive Oil when RV not in use
Doesn't turn rancid like some vegetable oils can


As for changing seal......really depends on Brand/Model of toilet
Some you have to remove toilet, separate base/bowel to change
So REALLY depends on WHICH Toilet.

That is why......1st step is thorough cleaning and lubing which many times is all that is needed


Is it time for your medication or mine?

The seals are not rubber, they are neoprene, and vasoline or any other petroleum base will not hurt them !

Toilet bowl seal lube

Used this once to rejuvenate a seal. Worked perfectly. I use it when unit is sitting. No more problems.

X2. I've used this a couple of times with really good results. I keep a container of in on hand for occasional use when the RV is going to be sitting for a few days or when the leaking problem reoccurs. Hope this helps.

We bought a new Mallard mh in '88. Bought a new Itasca in 2001. And another new Itasca in 2015.
Never had a problem with the toilets in the Mallard or the 2001 Itasca, but in the 2015 Itasca both the seal and the fresh water valve in the toilet have gone bad, and they are not replaceable. It's a Thetford.
I'm trying to find a new one. Because toilets come in different size configurations I went to a local RV Dealer. And was told that because of the Covid 19 they could not get net RV toilets for maybe a year. So I did some online shopping and ordered a Dometic, it came yesterday, and will not fit.
The detailed dimensions are in the instructions. If the dimensions had been in with the sales information I would have not ordered that model.
Not sure what we are going to do. Nowhere can I find dimensions published in any sales information.

I looked up the Dometic 310 and the installation manual is available online with all the dimensions.

Well, the olive oil did not do the trick. Must have a small crack in the seal.

The toilet is a Thetford Aqua-Magic II . Ceramic bowl. I'll have to look into a new seal I'm guessing....

Thanks for your thoughts!!

Exploded Parts List with internal Links to Manual, Videos etc

Bowel and base have to be separated in order to replace bowel seal...bolts are accessed via cutout on back of bowel.
If you have enough room between back wall and bowel---otherwise toilet has to be removed which would require a new floor flange gasket

Check the ball valve for cracks, chips, gouges which will allow water to leak from bowel

Good luck!
