Toilet gasket (for the bowl)

[Cidewayz]

I have a 2016 Wildcat maxx 312bhx. Does anybody know what model toilet is in the 5th wheel? My toilet doesn't hold water for barely any time so I'm going to replace the gasket. I'm trying to reach out before heading to the storage spot to find out so I order the correct one. Thanks!

RV manufacturers change suppliers of various components all the time.

The only way to be sure is have a look at your own toilet. Even another Wildcat may have a different make and model.

Look for a sticker on the back of the toilet. May need a mirror to see it or just pull the toilet up- easy to do and you'll want to do that anyway. Note that any time a toilet is pulled out, the foam gasket should be replaced and there are a couple different ones so get the correct one the first time.

A leaking seal on the ball fall can spell disaster if the tank happens to fill and overflow. BTDT... Replaced our problematic Thetford toilet with a nice Dometic 310.

Why can't they put the sticker somewhere where you can easily see it?

Then we’d have nothing to complain about.
Think about it......would you want the label on the front of your fridge, stove, dishwasher, Televisions, washer, dryer, etc etc etc?

Bet you’d be removing those real quick.

Thank you both! I'll make a trip over to my trailer.

Had the same problem. Problem solved. My dealer's service manager suggested periodically pour a couple of inches of mineral oil into the bowl. That lubricates the gasket. And when you flush, that also lubricates downstream gaskets. Also, I have found that if I let my RV set for a spell and the weather turns cold, the gasket shrinks just enough to drain the bowl.

Sometimes the flapper get out of wack, had that happen to me wouldn't hold water. Found a y- tube on it on how to reline it. Took care of mine....

Dometic suggests filling the bowl with hot tap water. It has worked for me. I had to do this twice after the camper sat all winter.

Take a toothbrush or any small brush and clean the gasket. Junk can get on the gasket and cause leakage. I also I purchased toilet gasket restorer from RV dealer and used.
I have never replaced one. Cleaning usually works. Mineral oil looks like a good idea. I might try that.

I used this and it worked:

My toilet ball began to leak. I turned off the water, put on a rubber glove and wiped the seal with a folded toilet paper square to remove any gunk on it. It has not leaked since.

I will try the mineral oil suggestion to lubricate it.

The bowl gasket (at the flapper/ball) is easily removed and cleaned by turning off the water supply and holding the flush valve open. You can grab it and pull it out. (just don't drop it in the tank) A little silicone grease or plumbers grease will keep it working all season. Reinstall and you are good to go. Wear protective gloves if that kind of thing grosses you out but unless you wear them to wipe your butt, it really isn't any different.

Also, our RV Dealer told us to be careful when you dump the 'blue stuff' in the toilet....try to keep it away from the gasket because it'll weaken the rubber. Our toilet isn't holding water right now, either. The flapper is cracked so they're replacing the toilet...thank goodness it's under warranty!

We agree - this stuff works great for us. And we tried mineral oil, olive oil, plumbers grease, and industrial rubber lube, and none of them do the job of the Tetford stuff.

You don't have to take out the whole toilet to fix the gasket on the flush ball on the Dometic 310. Just press on the lever to open the toilet ball and reach in and pull out the gasket. I bought a new one when we got our trailer and the instructions were on the package. Haven't needed to use it (6 years going on 7) yet and it hasn't leaked. Only thing we use is a little Dawn dish soap to clean the toilet and gasket. Pulling the toilet can be a pain and, if it's a Dometic, unnecessary. Thanks, for the tip about not pouring the "blue stuff" (presume some tank deodorizer) because it can ruin the gasket. I'll be sure to stay away from that, too.
