OK, I winterize my trailers well. But come Spring I have to deal with the possibility of a damaged toilet ball seal and the replacement hassle. I have tried the following.1. Put 1/2 gallon of RV antifreeze in toilet to keep seal moist and cover toilet bowl with plastic wrap to slow down evaporation. 2. Keep toilet bowl empty and dry.I'm replacing a seal right now.Has anyone tried spraying the seal with silicone spay or rubbing Vaseline under and over the seal? Then keeping the bowl empty.What do you all do?

I just pour some pink AF in the bowl. Not much at all. I've never found that it 'evaporates'. I check it about every other weekend during the winter. Always has the same amount in it.During the summer, when I'm using it, I always make sure it has water in it. Always holds the water between trips.It's the same seal from 2002 when I bought the rig brand new. I've never put anything on it other than the AF and water.Good luck!Mitch

I lube the ball seal with O-Ring Lubricant. (what I can reach of it with my finger)...Then some pink anti-freeze in the bowl.Don't use Vaseline. It's petroleum based and can actually harm the rubber seal.Lowes, Home DepotAqua-EZ-O-Ring-Lubricant

I've never replaced mine. It did start leaking a while back and I used a toilet bowl brush and stuck down the hole and gave the seal a good brushing, and the leak stopped. For winter I usually just put some pink in it, and that usually comes in when I winterize the water system.

I would never leave mine dried out without moisture on it. And I wouldn't use Vaseline. Could damage the rubber seal, but I see more of problem with Vaseline being sticking and that causing toilet paper or something else to stick to the seal and therefore NOT sealing tight anymore.I've seen a winterization product for the seal sold in stores but have just filled the bowl a couple of inches on mine with pink stuff and never had a problem.Bill

I pour enough olive oil in bowl to cover seal......doesn't evaporate & lubricates seal.It will turn slushy in really cold weather but causes no harm
