Normally we have the pump and well in our contract. This time, the HO had a buddy who put the well in for him, we just had the pump. Well is offset from pump about 18", no big deal. Pop 2 90's on, then check valve, pipe it into 1HP Versajet horizontal jet pump. Prime pump, leaving hose attached to faucet at T on outlet side of pump. All standard procedure. Run pump for 45 minutes, will not prime. Have another pump brought out on the theory that 1st pump may have been bad. Get it piped and wired in, hook up hose, this time same story after an hour of running. Inform builder of situation and continue to work on installing system. Builder calls: "HO just sent me a text, wants to know if check valve is on?" Me: "Yes, I installed a check valve." "But is it on?" "Yes, I put on one." "Are you sure it's turned on?" "Uh, it's a check valve, you can't turn them on or off." "Are you sure?"
