Leaks are the silent water wasters inside and outside our homes. A dripping faucet or constantly running toilet is fairly obvious, but hidden leaks—such as those in an irrigation system—could waste more than 100 gallons of water per day.

Catch leaks before they grow

Finding a leak is the process of elimination. Perform the following tests to find leaks at your home.

Make sure no water is being used inside or out

Also shut off automatic pool filters, sink faucets, washers and dishwashers.

Locate your water meter

About 90 percent of all area residential water meters are located in the front sidewalk. The first step is to check your water meter for movement.

  Meter
Find the source of leaks by turning off one fixture at a time and checking your meter.

Look at the top of the meter. You'll notice a red triangle called a flow indicator. It'll move whenever water is passing through it. If your meter doesn't have a flow indicator, you can use the sweep hand on the register to indicate water loss. If either the flow indicator or the sweep hand is moving, you may have a leak.

Check your toilets

Shut off one toilet at a time at the wall. In between each shutoff, go out to the water meter and check your flow indicator. If the small, red flow-indicator triangle is moving, that toilet is not the problem. Something else is causing a leak. If the small triangle stopped moving, that means that toilet is the culprit. For more information on how to find and fix toilet leaks, visit the SNWA Web site.

Check your sprinkler system

Shut off the anti-siphon valve that serves your sprinkler system. Check the red flow indicator triangle at the water meter. If the flow indicator stopped moving, the sprinkler system is the problem.

Check your water softener

Most softeners have a bypass lever. Turn the lever to allow water to bypass the softener. Check the red triangle at the meter. If the triangle is no longer moving, you have isolated the leak to your softener. (You also can check for leaking swamp coolers, water-cooled air conditioners, ice machines and reverse osmosis units by turning the bypass lever on each and checking the meter.)

Check your main service line

If you still haven't found the problem, try checking the main service line:

Find the water shutoff valve to your home. It will be either in your front yard, in your garage, or near your water softener. Shut off this valve, which will turn off all water to your home. Turn on a faucet to make sure there is no water flowing inside the home, then check the meter. If it's still moving, the leak is most likely between the shutoff valve and the water meter.

If you've found your leak, you may be able to fix it yourself. Repairs to toilets and faucets can be fairly simple, while other leaks may need a professional plumber. Don't get in over your head. If you're not sure that you can fix it, call a professional.
