About this item
- Sealing One‑Way Fastening: Critical sealing component in vacuum flushing systems that acts as a one‑way switch—effectively allows sewage to drain in one direction while tightly closing to prevent wastewater or odors from flowing back into the toilet and pump; regular replacement keeps the sewer system clean, hygienic, and functioning properly
- Flexible High‑Quality Rubber: Made of high‑quality rubber with a flexible, elastic texture that maintains good sealing during frequent opening and closing; resists hardening, cracking, or loss of elasticity over time for stable, reliable service life
- Easy Tool‑Free Replacement: When noticing poor drainage or odor issues, simply turn off the pump, remove the old valve, and install the new one in the same direction—no special tools or complex skills required
- Two Sets (Four Valves) Packaging: Thoughtfully offered as two sets (four duckbill valves)—use one set for instant replacement and keep the other as a spare for immediate response the next time a similar issue arises
- Easy Replacement: This 1-1/2'' black duckbill valve kit can replace the original part number 3853100764 and is compatible with Dometic/compatible with Sealand toilet drain pump systems (especially the S series, T series and other models). Its standard 1-1/2-inch interface is consistent with the original component specifications, allowing you to easily install it in place without worrying about size or compatibility issues when replacing it

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
