Camco Rhino Blaster RV Holding Tank Rinser The Rhino Blaster Tank Rinser creates a high flow blast of water into the RV's sewer discharge pipe, cleaning the black or gray water tanks. The clear 45 degree elbow allows the water to flow up the center of the pipes and directly to the tank. Regular tank rinsing helps reduce unwanted odors, reduces the risk of clogging and keeps sensors clean to ensure accurate readings. Attaches directly to the RV's sewer drainage pipe, so there is no need for sanitation equipment to be brought inside the RV, or brought back out after use. A vacuum breaker prevents backflow into the fresh water supply. Additional features include a 4-prong bayonet swivel fitting that easily and securely attaches to the RV's sewer outlet, and a swivel lug fitting to connect to the sewer hose.
