46+ Anti Siphon Vacuum Breaker PNG. Inquire with governing authorities for local installation requirements. July 5, 2016 5:52 pm subscribe.
The disc float and check valve are suitable for temperatures up to 140 degrees f.
This device is not to be used under continuous pressure or where there is a possibility that a backpressure condition may. A vacuum breaker is probably not what you want, or at least not the only thing you want. That only lets air in if you develop a negative pressure in the system. If i just pull the vacuum breaker assembly out of a new sillcock, rather than replace the whole thing, i wonder what the liklihood is that there is another leak/crack in the sillcock somewhere inside the wall.
