I posted on my fix on the Sealand, but after hearing about petroleum , not sure if vaseline is good, I will use plumbers grease the next time , but a good cleaning as I posted before ,and some sort of grease . Worked for me ,and that was six weeks ago.

good idea on the plumbers grease there bob. Why didn't I think of that years ago? :S

Any tricks to keep water in the Dometic/Sealand Ball type toilet?

Stay away from all petroleum based lubricants. We fill ours(to cover gasket) with olive oil when not in use as suggested by Chuck&Gail and it has worked great!

To MSGTRETIREDSP, we use SPRAY SCRUBBING BUBBLES.

When my previous RV's toilet started leaking past the valve seal I let all the water out and poured some coconut oil on the valve and let it sit (overnight if possible). It stopped the leakage for quite a while but wasn't a permanent fix since it had to be repeated in time.

My current toilet has a different kind of valve and so far hasn't developed the slightest bit of leakage.

Several years back the flapper seal on our toilet started having problems holding water. We nursed it along, scrubbing the rubber seal so it was clean and it would work well for a while. Then it would start to leak again. Eventually we had leak on the water valve, during a camping trip, and I pulled the toilet and disassembled to replace the water valve. After reinstalling it, the smell would come up through the toilet. I pulled the toilet again to discover the tank to toilet coupler seal was torn. The hole in the tank wasn’t aligned with the toilet and when I removed the toilet for valve repair, I finished off the rubber coupler. After waiting a day for the part, I finally got it all together. Again, this disaster was during a trip and was not fun.

My advice, if you are currently camping, use a pair of rubber gloves and a scotch brite pad to lightly clean the flapper seal so you can complete your trip. When you get home, or if you are home now, order a repair kit that includes the water valve, flapper seal, toilet seal, tank to toilet coupler, and top to lower seal. Buy a box of disposable rubber gloves.

Before you start, make sure the tank is flushed and then fill it half way with water and deodorant. Have plenty of towels, a couple buckets and your pressure washer set up. If possible, have a second individual ready to assist with tools, turning on the pressure washer, etc. That toilet will have some mystery stains that are not appealing.

I would tackle the task early. Use this as a motivator to eliminate a potential problems while traveling. Plastic and rubber parts fail. There is a reason these kits and parts are sold at so many places. Take it from someone who procrastinated and had to deal with this in a campground with a wife and daughter looking on.

I believe I was able to remove and replace the rubber seal on our older Aqua Magic (with slide lever) while the toilet was assembled. But I had to use care (and rubber gloves) to make sure I didn't drop it. The seal was only pushed into the recess at the base of the bowl.

I would remove the top half of the bowl. Then take the seal out and soak it in vinegar for a day or two. Then scrub the seal with some steel wool to remove all the accumulated minerals. Replace the seal and top half of bowl and you should be fine.

I've done this 3 times over the past 6 years and it has worked every time.

Just had that problem ,the seal is nearly six years old, and starting leaking ,not holding water in the bowl, cleaned it well with a round bristle brush about the same size in diameter as the the opening, and then with rubber gloves on put a coat of vaseline around inside and outside of the rubber seal, been working fine for the past six weeks. Before it would not hold water for two minutes. I think the key is a good cleaning of the seal itself, which probably does not get cleaned as well as it should with normal cleaning. Anyway it worked for us.

try vinegar to clean off the mineral desposits. this had worked for us many times. Pour some in and let it set for as long as it can before leaking down and do it again.
