Sprinkler head leaking after zone shuts off

I have a trickle of water coming out of the lowest point head after the zone finishes it's cycle. It will stop after a while. I thought it might be the head so I changed that and it didn't fix the problem. Did some research and read that it could be the diaphragm for the respective valve. Well took the valve apart inspected the diaphragm and it looked good. Figured while I had everything apart I'd change the diaphragm and solenoid anyway. Well after changing those an putting everything back together I'm still having the same problem, so needless to say I'm at my whits end. Don't know what else might be causing it. Any information or pointers on what could be the problem would be greatly appreciated. Thanks in advance for any assistance you can provide.
Oh yeah only other thing is this zone seems to take longer (aprox 8-10 seconds) for the heads to pop up then the other zones. Don't know if both problems are related.

Wasted efforts. Low heads will always drain when a zone shuts off. If this is a particular problem for you, then get heads that have a built-in check valve.

Your system works off gravity like the rest of the world, you said it your self.. Lowest head. It's draining until that zone reaches atmospheric pressure.

What brand head?

Install a SAM ( Seal-o-Matic) sprinkler head
