The Waste Master isn't just a hose and nozzle, it comes complete with a time-tested Cam Lock connector that ensures a leak-proof connection to the sewer outlet. Traditional RV hose bayonet fittings can leak, but industrial-grade cam locks have been used in the liquid transportation industry for decades and are proven to provide a strong, reliable seal. Unlike traditional hose coils that trap debris, the patented Waste Master hose is designed with its helical coil on the outside, while the inside is much smoother, preventing waste from getting trapped inside the hose. The UV-protected hose is 18 feet fully extended and 5 feet compressed including the nozzle. The hose also features technology that keeps it extended during use to the exact length required. The permanently-connected nozzle is molded with an easy-grip handle, an integrated shut-off valve and a clear view port that allows the user to see when waste has completely evacuated, helping ensure the tanks and hose are clean.
