Add these to your spare parts

I carry all kinds of spare parts, but failed to have spare toilet parts. Today the toilet (dometic 310) decided the bowl seal was in need of repair and would no longer hold water. I've seen this over and over on YouTube, but it never "clicked" in my mind to actually buy a spare. :rolleyes:

While inspecting the toilet, we also noticed a tiny leak coming from the foot pedal. So small, that it never tripped my water alarm behind the toilet. The water would circle the toilet and must have gone under?? This is caused by the valve that opens when you flush toilet started to fail.

So, we had to drive ~40 miles each way from our boondocking site to a town with RV parts. Yea...I paid waaay more than I should of, but simple supply/demand equation kicked into high gear.

I also had to shoot over the local Ace Hardware to get the silicon grease for the rubber seal. I now have both of these (the grease is enough for YEARS!) in my Amazon cart and will have them delivered when we get closer to home.

You can of course buy the lower cost water valve, but I HATE water/plumbing and don't want to save a few $$ to have water damage later.

When our flush valve leaked I replaced with domestic but also got a kit that has all three items from Amazon just in case because you know when it happens it will not be near a parts place. I also bought the vacuum breaker too. Lol🤣

Yep, get the glove out, clean the rubber seal from time to time and use the plumbers grease to help maintain the seal.
I recently had the same issue and a little vasoline applied to the seal corrected the issue of holding water in the bowl.

I have also heard(never tried) that some warm/hot water dumped into the bowl can help make the seal more pliable and conform to the flush ball better to help prevent leaks.

Without a doubt, I will be adding to my spare parts list as well, certain an easy fix for a potentially smelly problem!
Thanks for sharing!

You done right Jim. There are cheaper valves but it's best to use the Dometic brand. IMHO
Silicone 👍🏼 because I understand that petroleum products are not recommended for the rubber. Am I wrong?🤷🏼‍♂️

George, I don’t believe your wrong at all! Sometimes you just have to do what you have to do.
Personally, I would think the degradation of rubber caused by petroleum products would be a long term issue.
Just sharing a solution that worked for me to solve the problem at hand.
Again the power of this forum is to share individual experiences and provide solutions that work for individuals when they are experiencing problems.

Personally, I love to hear and experience the debate of given topics, the exchange sharpens all of our saws,

We have a very knowledgeable group here ! Personally, I value everyone’s input and experience !

Yes...from what I know and have read, you don't want to use petroleum based grease...if possible. I might use vasoline in a pinch (way out...boondocking) but I'd remove that and use silicone grease once I got back home.

I saw this approach on YouTube and it makes a lot of sense. Seems to have worked for many owners. We tried it but no dice. Wound up replacing the seal.

Good advice for sure. I have always carried extra seals for toilet flapper, but now I have 2 new parts on order!!

The hot water worked once for me and is worth a try if you don't carry an extra seal. Also with the ball open push down on the lip all the way around. And keep the bottom wiped clean. (OF THE SEAL)
.
My own personal tip is never let the seal be dry. At least use water or better — RV Toilet Seal Lubricant and Conditioner at least while unused for a time.
.
When I replaced mine (I don't need no instructions or YouTube) I struggled with it 4-5 times. I broke down and watched a YouTube. The trick is to silicone the seal and leave the ball closed. It snapped in in about 15 seconds.
