Thetford 33027 Aqua Magic IV High and Low Blade Seal

I bought a used Sprinter van, and the toilet smelled to high heaven. Part of the problem was that the toilet seal would not hold water in the bowl. I took it into a RV service center and they wanted $96.00 to replace it. I searched on google and it took a guy 5 minutes to replace the seal. I did it myself in about 10 minutes. No special tools needed. I tied a string to the seal to prevent me from dropping it in the toilet during the replacement. Glad I did.

This seal was very easy to install as I had already removed the toilet to replace the flooring, so it was installed from the bottom. I removed the old one and just slipped on the new one then lubed with a silicone grease. After re installing the toilet the first few times the flapper was a bit stiff to open but now works great and holds water in the bowl. Happy DW.

Easy installation, would recommend that you use gloves after installation and grease up seal with Vaseline and periodically after installation. Water stay's in toilet boal now!

Kinda difficult to put in place but Vaseline worked good does not tell you only in RV toilet diagram there is a track for blade wedge between blade & track grease really helps! Afraid of cracking blade not much room took out put back again got it !

Exactly the right size; no problems or hassles.
