> Minimum of 12" below the PVB
If I installed hose bib vacuum breakers, would I still need to be 12" below the PVB?
I will be installing my system in about 3 weeks.
(The SprinklerWarehouse boxes have arrived [
])
Due to my sloped lot, I'm running the mainline uphill to connect to the PVB. Two of these hose bibs would be installed at the highest elevation.
I'm starting to re-think the PVB decision.
My first thought was to install a double-check assembly to avoid the 12" requirement. But after reading the (hazard) controversy surrounding DCs, I decided on a PVB. My life would certainly be easier with a DC. An (expensive) RPZ would reduce too much pressure.
