How To Find A Water Leak With The Help Of The Water Meter

When was the last time you checked your customer’s water meter? If it’s within the last 30 days, that’s great. But if you’re not in the habit of regularly checking your water meters, there’s a good chance you’re missing a leak.

The water meter is an overlooked tool that helps you quickly detect if there’s a water leak somewhere in your customer's irrigation system. Horizon’s Bob Franchetto has put together a few tips and a video to show you how to find and correct leaks with the water meter.


Is There a Leak?

When you’re using the water meter to check for leaks, we’re not concerned about the large dial. When the large dial is moving, we’ve got a big leak. What you want to find is the low flow indicator. Sometimes it’s blue, sometimes it’s a little red triangle.

If the low flow indicator is moving when the irrigation system is shut off, there’s a leak somewhere in the system.

Finding the Leak

Step 1: Check if water is leaking.

Where the water is leaking is important. If the water is leaking on the city side, your customer won’t be billed for that water, but it still needs to get fixed. Leaks on the city side are the city’s responsibility and the city should be contacted to arrange service.

When the water is leaking on your customer’s side of the property, your customer is paying for it and it’s your responsibility to fix.

Step 2: Check the system from the meter to the valves.

If the water meter is running with the irrigation system turned off, then there is a leak between the meter and the valves. If the meter is running with the backflow turned off, you have just bypassed the valve and isolated the problem to the main. Your leak is between the meter and the backflow.

Step 3: Check if water is leaking out of the sprinkler heads.

When you have water leaking out of the sprinkler heads on a flat surface, you have a weaping valve. The valve is leaking. Let’s get it fixed or replaced.

And if the sprinkler heads are leaking on a sloped surface, you may need to install check valves. Without check valves, each time the system shuts off, every bit of water from the valve to the head is going to leak out. It’s a classic example of low head drainage.

The problem further multiplies when you cycle and soak the slope. If you don't have a check valve in the head when you cycle and soak, every cycle will produce additional low head drainage.

As purveyors of water, it’s our job to help our customers better manage their water usage. In many cases, we can dramatically improve an irrigation system’s efficiency with a few simple tweaks. It's the stuff we walk by every single day and don't pay attention to, but it’s easily fixed and it can save a significant amount of water.
