    dan o, the style of vac. breaker you mentioned is an older design. it has a 1 way spring. it will tighten 1 way and slip the other way. i've always used a die grinder to cut through the brass to remove.

    i've never been a big fan of the hose bibbs with built in vac. breakers. they always seem to hum if the hose is left on and the nozzle dead ended.

    i'm glad that you fixed the problem.

    now back to the translation issue. i'm confused

      "...hose bibbs with built in vac. breakers. they always seem to hum if the hose is left on and the nozzle dead ended..."

      These type of vaccum breakers (screw on style and the wall hydrants with integral vac breakers) are not designed to have pressure applied for long periiods. I think the design limit is like 12 hours. All those screw-on sprinkler timers that attach to hose bibbs defeat the purpose of a vac breaker if the timer shuts off and you don't relieve the pressure upstream of the sprinkler timer valve.
