Howdy, this is my first post. Sprinkler systems are a new thing to me and I would appreciate some help. I have an 11 yr. old Hunter System with 3 zones. One of the zones developed low pressure and some of the heads don't work at all. I tried digging out a few sprinklers to clean them but it didn't help. I can hear a knocking noise but can't isolate it. There are two valve boxes in the ground, I assume one for each zone. I've read that solenoids can be a cause for low pressure rather than clogged lines. Are they located in the zone boxes, and if so, should I be looking at replacing them? Any help will be greatly appreciated. I live in Texas and my lawn is burning up. Thanks!
