Review on Optimize Plumbing Safety with the Legend Valve 108 138 Vacuum Breaker by Patrick Reynolds

If you are looking for a vacuum switch to fit FUSAN 1019A this is the kit you need. With all the parts they send you as a kit, you'll find exactly the parts you need. Mine leaked a lot and after replacing the vacuum interrupter with the parts in this kit it was clean, dry and working great. To replace: unscrew nozzle handle, remove garden hose to relieve water pressure, remove cover with screwdriver, unscrew vacuum breaker sealing screw (plastic, you may need pliers for this), remove inner float. Install new inner float, screw in new stuffing box screw and tighten slightly with pliers, then put on new cap > ready in 2 minutes! No need to turn off the water lines or remove the faucet handle like some YouTube videos say.
