    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.
      "When we build let us think we build forever. Let it not be for present delight nor for present use alone. Let it be such work that our descendants will thank us for, and let us think, as we lay stone upon stone, that a time is to come when these stones will be held sacred because our hands have touched them, and that men will say, as they look upon the labor and wrought substance of them, "See! This our fathers did for us."
      John Ruskin (1819 - 1900)
