Backflow preventer

[Jesika Froman]

I'm constructing a commercial kitchen in my garage. The plumber we hired installed a hot and a cold line-like a spigot- for the mop sink. Our code requires the mop sink to have a backflow preventer. What is that, and can I install one the way it is now, or will we have to install an actual faucet?

I use these all the time for residential and commercial applications when there is a need for hot and cold water at a fixture

For a single C W hose bib I use a Watts 3/4 " Lead Free 8B, Hose Connection Vacuum Breaker
