Water Leak Detection: How to Check Your Home for Leaks

Top Signs of a Water Leak

A water leak is a seemingly small—but potentially destructive—problem. Because most homeowners are not going to start looking around for water leaks unless there’s an obvious sign that something isn’t right, here are some of the top signs of a water leak to look for:

Low Water Pressure

If the water pressure coming from your showerhead or faucet is lower than normal, there can be many different causes: a plumbing blockage, a closed shut-off valve, and more. Another common cause of low water pressure is a water leak within your plumbing system. If you’re experiencing low water pressure in more than one faucet at a time, the cause is likely to be a leak.

Damp or Moldy Spots in Your Home

Whether it’s a small water leak that has been problematic for a while or a larger water leak that just started, you may notice physical signs within your home. Be aware of any damp or moldy spots inside cabinets, on the walls, or on the floors—as these may indicate a leak.

A Drastic Change in Your Water Bills

Have you noticed a drastic increase in your water bills lately? If your water usage has remained the same or your water bills typically remain constant, it could mean that there’s a water leak within your home.

Dripping or Running Water Sounds

If you’ve been hearing any dripping or running water sounds within your home—even when no water fixtures or appliances are in use—there’s a pretty good chance that your plumbing system is leaking.

Where to Look for Water Leaks

Once you’ve noticed any of the above signs of a water leak, you can start to perform a water leak detection on your own. Note: Water leaks are not always obvious. The leak may be located within the walls or underneath the flooring. Here are some of the places within your home where leaks are the most common:

Inside Your Home

When searching the inside of your home, you’ll likely want to concentrate on the kitchen, bathrooms, the water heater closet, and the laundry room. Listen for dripping or running sounds and pay attention to any damp, dark, or moldy spots near the water source or pipes.

Outside Your Home

Water leaks can occur outside of your home as well. Take a look around your water meter for standing water and inspect hose connections, your AC unit, any garden irrigation systems, and a pool if you have one.

How to Test for a Water Leak

Here’s a simple way to test for a water leak in your home. Note: This won’t tell you where the leak is; it will only confirm that there is a leak somewhere.

Step 1: Turn Off All Running Water

Step 2: Check the Water Meter for Moving Numbers

Step 3: Leave the Meter Alone for 15-20 Minutes and Check Numbers Again

If the numbers change at all during steps two or three, you’re more-than-likely dealing with a water leak somewhere. At this point, your next step is to look into water leak detection and repair services.
