Our water was leaking and not holding any water. It’s was pretty nasty to fix but taking out the ring was pretty easy. We went to a rv store to get the part and the price was NUTS!! It’s a thick quality and it has been working way better.

Long story short after installing add hot water in the toilet bowl until it stops leaking.

Our RV toilet was not holding water in it after flushing so something had to be done. We watched a couple of YOU TUBES for problem and this is what 3 of them suggested doing and they also showed the correct way to change these in the toilet. We got them from Amazon sense they had the right size for the type of RV toilet that we have. It took about 20 to 30 minutes for my husband to change them, but it was well worth it since now our toilet holds water after flushing. Thank you Amazon for having these for us and getting them to us so soon after ordering.

All the YT videos made this look like an easy installation. I should have known better! It took me an hour and I’m still not happy with the fit.

Update: 12/16Failed literally after one night, not even 24 hrs later. What a waste of money.12/15:I have the dometic 320 series and yes this does fit and yes, actually putting it on is also easy. Getting it to seal and do its job? Not so easy. I fiddled with the seal for over 15 minutes taking it on and off but it was leaking water faster than my old bad seal. After multiple attempts and lots of plumber grease, I finally got it to hold water. This works in a pinch but I suggest another brand if you want a hassle free install.

These are easy to install. Fit my standard rv toilet. As recommended,I put a bit of grease around the top and now my toilet seals water tight.
