How Do You Find a Hidden Water Leak in a Home?

Turn off all water-using appliances and fixtures in your home. Then check the water meter. If the meter still moves, you likely have a hidden leak somewhere in the plumbing system.

This simple test can confirm a leak, but it will not tell you where it is. To narrow down the location, you can check the pressure or listen for the sound of running water. If the meter test shows a leak, move on to the next steps.

Hidden leaks often come from appliances like refrigerators, dishwashers, and HVAC systems. Pull these out carefully to check the supply lines and connections. A slow drip from a loose fitting can cause significant damage over time.

If you have a refrigerator with an ice maker, inspect the water line behind it. For a dishwasher, look under the unit for signs of water. If you cannot move the appliance safely, look for water stains on the floor or baseboard nearby. If you find a leak, turn off the water supply to that appliance if you can.

If you cannot find the leak yourself, or if the leak is in a difficult spot like under a slab or inside a wall, it is time to call local water damage pros. They have tools like acoustic listening devices and moisture meters to find hidden leaks without tearing up your home.

The pros can also help with cleanup if the leak has already caused water damage. They will assess the situation and recommend the next steps. In St. Petersburg, the humid climate means that even a small leak can lead to mold problems quickly, so acting fast is important.

• Use acoustic listening devices to hear leaks in pipes
