Winterizing Toilet Bowl Seal
I have a Dometic 310 toilet.
As part of my winterizing process, I have always left a few inches of antifreeze in the toilet bowl to keep the seal wet.
Last year, when I opened up the RV for the season, ALL the antifreeze had drained, which resulted in a dry seal.
I replaced the seal, using petroleum jelly to lubricate.
QUESTION: To winterize, would it be better to load up the seal with petroleum jelly, OR use antifreeze as I used to do?
