Review on Thetford 07101 Toilet Blade Seal by Scott Rodriguez

We have had several Thetford toilets over the past 25 years. Electric flush models work best. Replacing this gasket is usually caused by the formaldehyde toilet chemical coming into contact with it when you pour it through a large diameter hole to dump it into the holding tank below. If you take care not to get anything on the filling, it usually lasts three to four years, even if, like me, you go to the bathroom every weekend. This filling is very easy to change, anyone can do it.
