Vacuum Breaker
I live North of 466 and have a pressure vacuum breaker (pvb) on my irrigation system which I believe is code
My question is if there is another vacuum breaker for the rest of the house and if there is, where would it be located?
Or, are the vacuum breakers on the hose bibbs all that are needed. The hose bibbs are the only spots where contaminated water might enter the system.
Thanks
