I outfitted all sprays nozzles on the zone with Closed VAN's to see if the meter would stop completely, sure enough, still rolling a few gpm's worth when the zone valve is wired in.

Perhaps worth noting, the heads and valves in question are on opposite sides of the house. the outlet from the zone valves is pointing staight toward the new house addition which now divides the yard, (or valve and heads).

___ Thanks guys

P.S. what are my options on tracking the lateral line by cutting into it near the located valve, and attaching a (for lack of the correct term, "chatterbox", "sound-maker", "water pipe tracker".

I suppose a could run a wire down the lateral and track it with a 521, seems that might be foiled by a 90 , etc.

anyway, thanks again yall! (you fixed the hammer issue btw

Close it off again and induce air. Make a .25 npt adapter and start with low pressure. Increase pressure as needed. Sometimes a mixture of air and water has to be used but air will surface when water won't.

Don't get in too much of a hurry to cut or dig, you'll end up with a more harmonious outcome

BTW Rhett, your best bet to locate the pipe is dowsing with your voodoo sticks.

A chatterbox is a circuit interrupter for finding valves. A plastic pipe locator is too expensive for most of us to buy.

With some practice most anybody can be consistant with a single or pair of sticks.

Alright now I understand. Sorry, I was on day 3 of staring at a set sheet for a commercial bid... that's another thread through.

Did the original contractor build the house addition over a live lateral, which is now under the house? I have never had that happen on a house addition, but I have seen a lot of patios built over live irrigation laterals that ended up breaking.

You might call in a plumber or rent a snake with a camera, then scope the drain tile and see where the water is coming from. It will at least get you closer.

That was going to be my recommendation as well. Turn off water supply, and use an air compressor to try and force either air bubbles or loose dirt to the surface. Do you know where all the zone valves are? You could also turn flow controls off and see if that helps. Do that one by one.

I've induced air to find a leak also by looking for bubbles.I've also put the screws to the system AFTER I told the client that this is a last resort as the chances of blowing the offending leak out of the ground are real good.

I forgot: we had a bucket of these for not only install caps, but to trouble-shoot leaks.

great advice if nothing else, cuz air is much easier to find than water when it comes to leaks.
