Did a service call today, customer had a system installed by a rival company one year ago. Wanted some hydrants installed, and for us to fix many problems with poor coverage...or so it seemed. When I got there, the fun began. I wasn't able to fire half the zones from the timer ($59 Home Depot Orbit Timer), so I had to find the valves (all in 6" round boxes, no manifolds) around the yard and fix numerious wiring problems before I got that working. Once the zones were coming on, I discovered a cracked male adapter on one valve (valve box was resting on it), so I repaired that. I had to find the shutoff to do this, when I found it, it was simply a PVC ball valve, no backflow at all Fired it up, it was a drip zone, fixed 6 breaks in the drip tubing. I had to move a bunch of heads in the backyard, all of them were set too low, and in odd places. Got decent coverage after a hour or so. Found a real winner on one, Hunter PGP, set too low and it wasn't retracting...When I looked closer I discovered that the nozzle was installed upside down and the two ears where keeping it from closing...And this company considers themself professionals The real fun began when I got the front yard. One zone had about 10 rotors on it and 5 sprayheads...Matched Precipitation anyone? The odd thing is that the sprayheads should have been rotors given their location. There were numerous breaks that I had to repair before I could get an idea of how bad the pressure situation was. I started replacing the sprayheads and discovered that they didn't bother to use swing joints on the front yard.... The sprayheads were all the HD orbit sprays except for one, which was a ancient brass rainbird popup...No clue why that was in there. The next zone over was supposed to water a roughly 60'x80' area. They accomplished this by using about 25 sprayheads....Of course, none of them did anything but pop up 1" and pee out. I'm coming back on monday to rework that zone into a rotor zone. The only other thing to note is that I found 4 different types of glues on the fittings (yellow, black, Dark blue and light blue)...but the homeowner said that they haven't had anyone else there. Weird...and frusterating. I hate having to be the bearer of bad news to home owners on how much they got ripped and what its going to cost to fix it.
