How to Detect a Water Leaks

Identifying leaks early is important because it helps protect your home from costly damage while also conserving water and reducing your utility bill.

Look for Signs of Water Damage

Stains on walls or ceilings.
Musty odors or mold.
Wet spots on floors or carpets.
Unexplained increases in your water bill.
Sounds of running water when nothing is in use.

How to Detect a Water Leak with my Water Meter

You can use your water meter to check for leaks at home.

Steps to Check:

Turn off all faucets and water-using appliances.
Find your water meter, usually located in the front yard.
Look at the leak indicator (a small dial, triangle, or star-shaped symbol).
If the indicator is moving—or if the meter reading changes after 1–2 hours with no water running—you likely have a leak.

Isolation Method for Detecting Continuous Leaks

The isolation method helps you locate where a water leak may be occurring.

Steps:

Make sure no water is running inside your home. Check the water meter’s leak indicator.
Shut off your home’s main water valve.
- If the indicator stops, the leak is inside your home.
If the indicator keeps moving, shut off your irrigation system.
- If it stops, the leak is in your irrigation lines.
If the indicator still moves after shutting off both the home and irrigation valves, the leak is in the service line between your meter and the shutoff valve. In this case, contact a professional for assistance.

How to Detect a Pool Leak

Pool leaks can waste water and increase costs. Use these steps to confirm and locate a leak:

1. Start with a Bucket Test

Place a bucket filled with water on a pool step and mark the water levels inside and outside the bucket.
After 24 hours, compare the levels. If the pool water drops more than the bucket, you likely have a leak.

2. Inspect the Pool and Equipment

Check the pool structure, liner, fittings, and equipment for visible cracks or damage.

3. Use a Dye Test

Release pool-safe dye near suspected areas.
If dye moves toward a crack or opening, you’ve found the leak.

4. Test Plumbing and Surrounding Areas

Pressure test the pool’s plumbing.
Look for wet spots near the equipment pad or around the pool area.
