i had a guy do my concrete so he disconnected my system. he ran a 3/4 pipe underneath the concrete and he said he shut it off.
so, now im trying to route new pipes and sprinkler heads, but first how do i turn this back out and do a test? the system is automatic and is only a few months old. i was touching and turning the 3 knobs, but all i get is water spraying from the valve.
i just want to make sure the guy didnt screw it up. he was gonna charge me $200 to install 3 heads and a 30ft. pipe.
