Shopcorp RV Black Tank Flush Kit, 3-Inch Gate Valve, Clear 45° Reverse Flush Adapter

RV Black Tank Flush Kit with Clear 45° Rinse Chamber The Shopcorp RV Black Tank Flush Kit helps rinse residue from compatible RV black tanks, gray tanks, drainage outlets, and sewer hose connections during routine waste-system maintenance. Its clear 45-degree reverse flush chamber connects between the RV sewer outlet and drain hose, allowing rinse water to be directed toward the RV waste outlet while giving you a visible view of the water flow. 3-Inch Gate Valve for Controlled Sewer Discharge The integrated 3-inch manual gate valve uses a pull handle to open or close the discharge path. This provides additional flow control while connecting, rinsing, or servicing a compatible RV sewer system. The valve does not replace proper tank valves or safe dumping procedures. Always confirm that the RV outlet, sewer hose, and dump-station connection are secure before opening the gate valve. 45-Degree Reverse Flush Connection The angled transparent chamber is designed to help direct rinse water back toward the RV drainage outlet. This reverse-flow configuration can help loosen and rinse residue from compatible black tank, gray tank, and sewer outlet systems. Its 45-degree shape also helps position the sewer hose away from the RV connection for a more practical setup. Clear Polycarbonate Chamber for Visual Flow Monitoring The transparent polycarbonate chamber makes it easier to observe water movement and monitor rinse progress during use. This visual design helps the operator determine when the outgoing rinse water appears clearer before disconnecting the system. 3/4-Inch Water Hose Connection A dedicated 3/4-inch water hose port connects to a compatible rinse-water hose. The integrated valve knob lets the operator turn the rinse-water supply on or off at the adapter. Use a hose reserved exclusively for sewer-system maintenance. Do not use a potable-water hose for black or gray tank rinsing. Universal RV Sewer Connection The kit includes a compatible RV-style bayonet connection designed for commonly used 3-inch sewer outlets and hoses. The four-hook fitting helps secure the adapter to a properly matched RV waste valve connection. Always confirm the connection pattern and dimensions before purchase because RV sewer components can vary by manufacturer and installation.
