Review on Thetford 34120 Waste Style Toilets by Michael Boyd

I think this is a common problem with RV toilets that have ceramic bowls. I tried lubricating the original valve with no modifications, thinking the old one was dry. A new one came in, now it holds the water perfectly. I wonder how long this will take. I didn't notice any damage to the old one, so I'm writing it off as a design flaw in the gasket. It wasn't bad to set up. It took about 15 minutes and only had to remove the bowl, not the entire toilet. Just glad to have a working, odorless toilet again.
