Review on πŸ’¦ Camco 39312 Sewer Hose Seal - 4" x 3" - Ultimate Leak-Proof Solution for RV Sewer Connections by Mark Bearden

Revainrating 5 out of 5

Most sewer hoses don't need this donut.

I bought this because Florida requires a donut for all RV drain lines. I hadn't driven our new RV for the first time, so I didn't realize my sewer hose fitting had a universal adapter, so I never used that donut. For this you need a waste water hose with only one bend. It didn't cost much so I left it. I'm thinking of adapting it to fill the gap between my sewer hose and the inlet in the drain to keep rodents out.
