Keep your RV in working order with the Camco Rhino Blaster RV Tank Rinser. This tank rinser latches securely onto your RV's sewer outlet. The 45 degree angle of this tank cleaner allows water to blast directly into the outlet, rinsing out residue. This sewer tank attachment features a clear elbow so you can see when the water runs clear. The vacuum breaker included with this polyethylene attachment prevents backflow into the water hose.
