Leak Detection: Find Problems Before They Grow

Small leaks, large bills

This page is for hidden or slow leaks when you don’t know the source. Active spraying or a ruptured line is burst pipe, not leak detection.

Slow leaks behind walls or in irrigation-adjacent lines can raise bills, feed mold risk, and damage structures. This guide helps homeowners gather clues when the source is unknown. A leak under a slab is slab leak. A dripping tap is leaking faucet.

Why leak detection matters

• Unexplained spike in water usage
• Damp drywall, staining, or peeling paint
• Musty odors in closed rooms or cabinets
• Warm spots on floors (hot-water line leaks—careful interpretation)
• Sound of running water when all fixtures are off

Active flooding? Leave this page: burst pipe and emergency plumbing.

Homeowner detection checklist

1. Visual sweep: under sinks, basement framing, ceiling stains below bathrooms. A drip at the faucet belongs on leaking faucet. If standing water is clearly at the water heater, use leaking water heater.
2. Toilet that refills on its own: that’s a running toilet, not a hidden-pipe hunt.
3. Listen: quiet house, ear near walls/utility rooms.
4. Feel: unusual dampness on carpet edges or baseboards.
5. Irrigation / hose bibs: outdoor leaks can look like “mystery” usage.
6. Appliance hoses: washing machine and dishwasher supply lines—inspect for bulging or seepage.

Water meter clue (where accessible)

If your meter is readable and you’re comfortable:

1. Turn off all water-using appliances and fixtures.
2. Note the meter reading / leak indicator.
3. Wait 15–30 minutes without using water.
4. Check again—movement can indicate a leak (or a fixture that didn’t fully shut).

Not all properties have easy meter access (apartments, some HOAs). Don’t force locked lids.

When to call a professional

Call (844) 936-0420 if:

• Meter suggests continuous flow and you can’t find the source
• You suspect a slab leak (warm floors, unexplained usage with no visible source)
• Drywall moisture keeps returning
• You need specialized listening equipment or camera inspection
• A leak is near electrical systems

Ask what’s included: acoustic detection, camera, pressure tests, and whether repair estimates are separate.

FAQ

Can you find the leak over the phone? No. Phone triage helps prioritize; location usually needs on-site tools.

Will leak detection always require tearing out walls? Not always. Many pros start with non-invasive methods; access openings depend on findings.

Do you offer a warranty on finding every leak? We don’t perform the service. Ask the provider about their process and any guarantees they offer in writing.
