How It Works
RV Sewer Guard Insert installs inline with your existing sewer hose using a standard clear tube. Inside, a spring-loaded valve automatically opens during water flow and closes when flow stops.
This creates a normally closed seal that helps prevent backflow, sewer gases, and pests from entering your RV system without any manual operation.
Why It Matters
Gray tanks fill quickly from everyday use, including showers, sinks, and laundry. RV Sewer Guard allows continuous discharge while adding an extra layer of protection to your sewer setup.
No more worrying about backflow, odors, or unwanted intrusion—just a cleaner, simpler RV experience.
Built for Durability
RV Sewer Guard is constructed with UV-resistant ASA plastic and stainless steel components for long-term outdoor durability.
The replaceable silicone flapper seal is designed for extended service life and reliable performance in RV environments.
Compatibility
Compatible with select 5" clear RV sewer hose adapters, including Valterra® T1021 and Camco® 39572.
