Turn off the set screw on all sprinkler heads, forcing the water to go to the leak...the leak will then be more obvious and perhaps you will then find it.

this, by the way, is why doctors don't diagnose patients over the phone.

Come on guys, that's the easiest trick in the book! lol[8D]

I'll have to use that trick the next time I'm looking for a leak.

didnt think of that!!!

Very true Sprinkler Guy

I would dig up the sprinkler heads.....and check them...its possible some large debris could be in the line and finally mad eit to the sprinklers. or as bhungue2 stated it could be leaking downwards.....if all the sprinklers are low it would be before the first sprinkler on the line...

There was this one time when I had to find the problem with lost pressure in a zone, after hours of digging here and there and listening at each sprinkler head for leaking I finally found the problem. Sure enough there was a leak but because there was so much rock in the area (specifically lava rock) The water instead of creating a swamp in the lawn created kind of like an underground river. It could flow freely because of all of the space in the rocks underground. If all else fails turn the zone on and try to follow where the pipes most likely would be. And listen very very closely. Good luck!

Hi,
I replaced the valve and the pressure is still low. I had to replace two sprinkler heads with pop-ups to get the thing to work. I'm thinking a tree that was planted some 15 years ago after the system was installed maybe pinching the line somewhere. I know the line goes directly under some very large roots. I don't know what else could be the problem. This zone was working fine earlier this summer, then something changed. I shall not be defeated by this! Help! Thanks again...Frank

I would replace the valve. Simply take out he "guts of the old vlave and replace with new. Most likely the soleniod pin isnt sealing, there is a mircroscopic hole or grass in the valve. I would replace it and see what happens. Also look for a hole in the diaphram (rummer) part of the valve.
