I have been assigned to take over our church's sprinkler system. The property is ten acres, so it's been quite a job. I have all the zones working except one. When I turn the valve on manually to that zone, I can hear water running, but no sprinkler heads pop up. When the controller turns on the valve, I also hear water, but same result...no heads pop up. I can't remember the brand of the valve right now. It has three letters and the numbers like 220-050. Any help would be appreciated.
I forgot to add that I know nothing about sprinkler systems...but am slowly learning.
I remember now, the brand is HIT 220-050.... maybe 250 or 215-050. I can go look at it again if it makes a difference.

HIT is a fringe brand name, with little pro installer history. If the entire system was installed with the one make and model of zone valve, you will become skilled at maintaining them, and you will start by having a spare valve on hand at all times, so you can do a complete swap of all parts, if needed.
