I have in-ground irrigation that was here when I bought the place. Runs off a standard well and pressure tank that's between 50-60 PSI. I've got 6 zones in the yard each with 5-7 sprinkler heads that run together in each zone. The well pump runs constant when a zone is active but it keeps up. All lawns around me are a similar setup. Poly is going to every zone valve and sprinkler head in series
