Why?



In the US you don't need a back flow valve for water coming from a

hose bib, it already has a back flow valve from the main, the entire

residence is protected... back flow valves are required for automatic

irrigation systems because they are typically supplied directly from

the water main before the residential back flow valve. But not

knowing the codes where you live you may want to check... but water

from a hose bib I seriously doubt needs a backflow valve... you've

probably been using the hose bib to irrigate from since the house was

built

This discussion has been VERY interesting! Just to be 1000% sure, I'll check out local regs, but I suspect you're right about the hose bib being protected.
Tx to all.
