    Could be the valve, or it could be tree roots choking the pipe. Sounds like the valve isn't opening all the way, or there is an obstruction in/around the pipe.

    When the zone is on, try adjusting the flow control if you can, and listen for changes in the flow through the valve. If you need to, do it on a functioning valve so you know what to listen for. Based on your results, that should point you in the right direction.

    If you are on a meter, compare the gpm of each zone.

    If on a well, time the drawdown time of the zones.

    Wells are a little more difficult to measure, the pump has to be shut off and then the zone turned on and timed. There will be a click when the pressure switch cuts-in.

    Im thinking tree root too. I would dig up the first head , cut the pipe and see what ya have for flow there.Depending on what the site looks like.If flow susks shove a garden hose down it. If zone comes up ya know your problem is before that point. If so , just pull a new pipe to there.
