The Shopcorp RV Black Tank Flush Kit combines a clear reverse-rinse chamber, a manual gate valve, a water-hose connection, and RV-style sewer adapters in one assembly.

It is designed for routine maintenance of compatible RV black tanks, gray tanks, sewer outlets, and drain hoses. The transparent section helps the user observe rinse flow, while the pull-handle valve and water-control knob provide separate control over sewer discharge and incoming rinse water.

RV Black Tank Flush Kit with Clear 45° Rinse Chamber
The transparent 45-degree chamber creates a visible connection between the RV sewer outlet and the discharge hose while helping direct rinse water toward the waste system.

3-Inch Gate Valve for Controlled Sewer Discharge
The pull-handle gate valve opens and closes the main 3-inch discharge path, helping control flow during setup and rinsing.

Clear Polycarbonate Chamber for Visual Monitoring
The clear chamber allows the user to monitor rinse-water movement and visually track the progress of the cleaning process.

3/4-Inch Rinse-Water Port
The side port accepts a compatible 3/4-inch hose connection and includes a dedicated valve knob for controlling rinse-water flow.

Compatible RV Sewer Connections
The assembly is designed for commonly used 3-inch RV sewer outlets and hoses with an RV-style four-hook bayonet fitting.

Important Use and Safety Information
Use only at an approved RV dump station or other authorized waste-disposal location. Wear appropriate protective equipment and keep the rinse hose separate from all potable-water equipment.

Close the water supply and gate valve before disconnecting the assembly. Check all seals and fittings for secure engagement before each use.
