This unit is a Vacuum Breaker, this unit if installed heigher than the source will allow Air to enter the hose draining the water from that hose when shuttoff. if the faucet or the source is lower than the hose the water will flow out of the braker. If it leaks under pressure the unit is bad and needs to be replaced.
