Arrived at location and found a 3/4 pvc line was separating at the joint. We then found a w/m angle stop was hard to turn on and off. We then rebuilt the sprinkler system line with copper pipe and fittings. We then turned water back on and tested for leaks there are none. We then backfilled and cleaned area. We then went to the garage and worked the valves so they are easier to turn. Everything is working properly at this time
