Hey guys, so far in my first season of repair work, I have not had anything hard that I have come across, until today. A home owner calls saying her system wont turn on at all, so I head out and take a look at it. The husband had already dug up the DCVA and what he thinks is a valve (which is a shut off fitting). First thought, something wrong with the box, its a Hunter XC box. Looks to be running fine, has a weather sensor attached, I bypass it and turn on a zone, nothing. I take a look at the holes that were dug, full of water and the home owner says one side of her yard is always wet. She called the city and the city says there is no leak b/c no water is shown running at the meter when all water in the house is off. The city says she has a natural spring in her yard, that's a first for me to hear that about a yard. After cleaning around the DCVA, i check to see if that has been turned off. Still on, but one of the handles will not turn off, it goes about 1/8 of the way and then feels like its hitting something in the pipe. The handle is rusted bad and didn't want to force it since i could tell the handle was about to break. The other one turned off and on with no problems. After shutting the handle off i could not hear anything when i turned it back on, i usually hear water flowing back through or something. I go to a valve, and try to turn it on manually, no luck. I open it up expecting if there is water pressure that I am about to get a bath. Nothing comes out. Same of the 3 other valves that i found in the yard. So with the DVCA turned on and the shut off fitting wide open, nothing is coming out of the system, there is no lose in water pressure at the house and the meter is standing still. My guess is something it clogged or broken with the DVCA, but with my 2 months of hands on experience, I come to the you guys, the pros What do you think? Am I on the right track?
