I think you are right about a leak, RichMoney. However, the leak must be in the PVC pipe that supplies the drip zone. I have removed the pressure regulator and drip tubing from the PVC, and there is no flow to the drip tubing. So, I am going to have to dig up the underground PVC. Not much fun, since the piping has been in the ground for 11 years, and there is no visible sign of water from a leak. :evil:

I would say you have a leak. If there are no visible signs of a water leak, you can spot dig the drip pipe and kink it or cut it to measure flow.
Start close to the valve and work your way out. That's the hard thing about drip, with pressure regulator, filters, and branching off wherever the installer feels like it, it makes repair work a headache.

Thanks, but I know that the valve feeds the drip zone. I was here when it was installed, and I have not changed it. Also, when that zone's valve is open AND any other zone is opened, the flow rate to the other zone drops drastically.

I'm thinking the valve you're opening doesn't go to the drip.
Or, it's a modified line that used to be sprinklers and now it's drip so the leak is somewhere in the old abandoned line that's still hooked up.

No Flow To Zone, but...

There is no flow to one of my zones. However, when I open the control valve by hand, I can hear a rush of water. With the control valve open by hand, there is a significant drop in flow to the rest of the system. For example, my hand-held hose flow drops by more than half, or another manually opened zone barely gets any water flow. The length of underground PVC pipe from the controller to the zone outlet (it is a drip irrigation zone) is no more than 20 feet, yet there is no evidence of a broken pipe (i.e., water seeping out of the ground). Any ideas?
