Exclamation How to check for leaks in Automatic Sprinkler system

The water bill is high. Had all the toilets and faucets checked and fixed. But still the water bill is high.

We have an automatic sprinkler system. And there was a construction done before around the house which might possibly hit the sprinkler system.

Since the yard is divided into several zones by the sprinkler, how will you know if there are leaks in that particular zone?

Is there a way aside from digging all the sprinkler tubes underneath?

If you are on a municipal water system (I assume you are) then the easy way to determine if you have leak is to first shut off all water consuming devices in the house including icemakers and toilets.

Then look at your water meter. Somewhere on the face will be a "tattletale" device. It may be a "winking eye", a sweep hand or a little triangle or something like that. If it is moving then water is flowing. It should be absolutely still and not move the slightest. Watch it for a few minutes to be sure.

If it is moving then you need to isolate the leak. Your sprinkler system will have a master shut-off valve and also branch shut-off valves although the branch valves may be only the electrically operated from the sprinkler timer. Shut off the master valve and again check the water meter. If the tattletale is now stopped then you know the sprinkler system is the leak. If the tattletale is still moving the main line from the meter to the house is leaking.

Post back and let us know the results.

Thanks for the post furd.

There is a free water inspection provided by the county which checked the toilet and faucet... But the yard is not included in that inspection , so I pretty much rule out the interior plumbing.
