Sealand 385319054 Vacuum Breaker with Hand Spray - Anti-Siphon Valve for Garden Hose, Outdoor Faucet & Watering System - Perfect for Lawn Irrigation, Car Washing & Pet Cleaning

Perfect replacement. The RV toilet was leaking in the back from the rubber seal and the plastic breaker valve that slides into it was growing black stuff out of the top apparently. SO long story short no more leak or black stuff growing out of the breaker valve thing. We decided to order the one with the spray handle and it works perfectly too.
