I'm considering running water to my pool house and looking for the best (inexpensive) way to do. I'm thinking of tapping into my sprinkler supply line coming out of the house and running it that way. It would be with Pex tubing and I'd have the PB run it before the deck is poured. I could blow the line out with the sprinklers to avoid freezing during the winter. Does anyone have any thoughts on this? Thanks!
