Description
Product Overview
The Thetford 2372274 Toilet Waste Tank Automatic Vent is a genuine OEM replacement vent designed for Thetford C200 Series cassette toilets, including the C200CS, C200CW and C200S. Mounted on the portable waste holding tank (cassette), this automatic vent valve opens as you empty the cassette, letting air into the tank for a smooth, controlled, splash-free pour, then closes to help seal in odors during use and transport.
If your C200 cassette glugs, splashes or empties slowly, or the vent button is cracked, sticking or leaking, this genuine Thetford automatic vent restores clean, easy emptying and odor-tight performance to your RV, camper van or caravan cassette toilet.
