Low pressure in zone

Zone two of my five zone system has recntly lost pressure and has very weak output (water is barely trickling out w/o enough pressure to lift the heads.) Can anyone tell me what's wrong and how can I fix the problem?

The valve feeding that zone may need serviced. It sounds like it isn't opening fully.

If you are a do-it-yourself type, you may try replacing the valve diaphragm or troubleshooting the problem yourself, however it may be cheaper (money and time wise) in the long run to just replace the valve

cap off one head @ a time to see if there are any leaks that show themselves ,if thats not it you might have a valve problem like a rock in it ,remove top and check after you shut off main .
