If you don't get the shower then it is not relieving pressure - does that mean it is not functioning properly? After you shut off the water is there still pressure in the hose?

Victor, I could be off my rocker, but I have assumed them to be check valves. Under normal ops, the 60ish psi water pressure allows flow to hose. With the spigot valve off, residual water pressure remains in my hose until relieved at the nozzle. With new valves - vacuum breakers - I get no leakage/relief/dripping at all at the spigot. Mine now behave as if there were no vacuum breaker at all. I contemplated not replacing them but ultimately did.
