    Long time reader, first time poster on the irrigation side, Homeowner also so be gentle. I have a seven zone system installed, using irritrol valves, hunter I-20 and hardie heads. When I turned the system on, zone one heads popped up, but no water came out. All the other zones functioned properly, this is only an issue with zone 1. Any idea what is causing this?

    Thanks in advance,

    The popped up, but no water is spraying out? Sounds like your sand screens in the heads are clogged... That would have to be a lot of sand however... You say they popped up, are they all fully in the up position? are some oozing water? or did they just go up and then back down again?

    They popped up, the dog and I just stood there looking at them like they were going to talk to us. I shut the zone off, they went down, and I turned on zone 2 and zone 2 functioned properly.

    I-20 heads have a center shut-off valve, marked in the rubber cover.
