How Do I Do a Simple Water Leak Test at Home?

Your water meter is a reliable tool for spotting hidden leaks. Start by turning off all water inside and outside your home, including ice makers and irrigation systems. Then, find your meter, usually located near the street or in a utility box, and record the reading.

Wait at least one hour without using any water. Check the meter again. If the reading has changed, you have a leak somewhere in your system. A steady meter that stays the same means your plumbing is likely sound, though some slow drips may not show up in a short test.

Look under sinks, behind appliances, and around water heaters for dampness, corrosion, or small puddles. Feel the pipes for moisture, and check for green or white mineral deposits on fittings, which often indicate slow leaks. Pay special attention to areas where pipes connect.

Also, examine the floor around the base of toilets and the walls behind washing machines. A musty smell or discolored drywall can signal a leak inside a wall. If you spot any signs, address them quickly to prevent further damage.

• Check under every sink for damp cabinet bases
• Look for rust or corrosion on pipe joints
• Feel for moisture on exposed pipes after a dry wipe
• Inspect the area around your water heater for puddles
• Note any unexplained increase in your water bill

If your meter test shows a leak but you cannot locate it, the problem may be in the slab, walls, or underground pipes. Hidden leaks require specialized equipment to detect without tearing into your home. In such cases, consider contacting local water damage pros for a thorough inspection.

They can use acoustic listening devices and thermal imaging to pinpoint the leak. Once found, the repair may involve opening a wall or floor, which can cause water damage. If you have significant water damage from a leak, water damage cleanup services can help restore your home.
