NYbirdman,
A friend of mine hit a sprinkler while working and it went to town. Stinky nasty water flowed. But I'm guessing it was iron pipe. I'd guess Cu and pex would not have near the effect on the water to make it so nasty?
But in any case, my local Pb-ing supply house has a Wilcons double check valve for $27. Not sure if it has a port between to check for back flow. I wanted to presure check to system before Drywall went up so I installed two shutoffs, one above and one below where the backflow preventer would go. The one above/beyond the backflow preventer has a drain back port. I supose I could replace the lower one to have the drain port and consider it to a backflow check point. It would have to leak past both though.
