WORK GREAT.
This is sooo good that my neighbor ran off with it (accidentally). I need to reorder more. Works great for my RV.

Stops leaking toilet bowl
After a few trips with a new RV we started having trouble with the toilet bowl not holding water. We tried this stuff between trips and the next trip was much better. Applied more before the next trip and the problem has not returned. It seems to not only condition the seals, but also lubricates. We noticed that the ball stop sometimes wouldn't seat completely and that was why the leak was happening. It was leaking down almost every time. After the first use only noticed one time on the next trip, after the second application it isn't happening anymore, and it seems to work much more smothly too.

So far, so good!
So far, so good! I was having trouble with my toilet blade valve leaking periodically. I dumped in enough of this treatment to cover the seals and let it sit overnight, about six hours. I’ve been dealing with kidney stones since November so the toilet gets lots of use. Since I used this treatment I’ve not had any more leaks.

Works as it should
I used this to recondition my toilet seal, which was leaking when I first got my camper. After I put this in the bowl a few times, now it makes a good seal and holds water in the bowl again.

Good Seal Lube
This product actually works. Our RV toilet would not hold water. Instructions say to leave it in the RV toilet for 8 hours, but I left it in for an entire week while we were away. When we returned, the toilet was as good as new!

Works alright.
This stuff didn’t work as well I had hoped it would. I left it in the toilet and it didn’t seem to help it open or close any. But it did come fast and it was very easy to use. I continue to use it because I still have a whole bottle and If there is a chance it will prolong the life of the toilet then I’m willing to try it.

This should stop the seal perishing over the winter when not in use

Can use sparingly. No need to dump a bucket in. Just cover the seal. Rejuvenated 20yr old seal in trailer. Seals great again and slides nice.

Ce liquide agit rapidement sur le sceau d’étanchéité et le morceau qui pivote Je recommande

RV toilet seal issues, this product has served us well for short or long term RV storage. Keeps the seal lubed for smooth ball function. Ya i really said that. But remember we are talking about your RV toilet.
