Need some advise. I have a HO that wants me to install a frost-free faucet on the mainline that we are extending to expand his current system. We are going to put a 2 zone / 8 head expansion around a play area behind his property that we just finished installing a metal fence around. He has a 3/4 poly system in place, and the meter is about 200' away with about 15' elevation between the meter and new zone. Now typically I would never ever consider this, but with the type of ground we are dealing with and the distance to run an independent service line just for a faucet has given me pause. What are your thoughts? Remember, i'm still a rookie would like any advice. we are going to remove the gravel and place sod around the perimeter of the wall. Sorry this is the only pic I have.
