The home is a 2001 build with publis water and a **septic system.
**[size=2]Is it required to have a back flow at the faucet by the main. Are the requirments the same or are they different since this is a private waste system.
Is there potential for a cross connection at this valve?
Thanks

No reason to have backflow preventer unless there is a sprinkler system in the house.
That’s new to me. Never heard of a backflow needed at the water main.
Dave,
This appears to be a regional thing even in OH

There would have to be some really bad problems with the entire system for CC to occur from the septic
This looks familiar.
I heard of it recently from a local inspector who has a brother in IOWA that recently got a certification to inspect these configurations. Just a few in the state are certified and it seems like it could be a good $$$$$ making opportunity.
Yes there should be an anti-siphon valve on the faucet (hose bib) by the main valve.
