Leak detection in Apache Junction: find it before it spreads

Most homes in Arizona are built on concrete slabs, and many have water lines routed beneath them. When one of those lines leaks, the water can go unnoticed for a long time. The first clue is often a water bill that does not match your usage, a warm spot on a floor, or the sound of running water when everything is off.

Leaks can also occur on the water service line, which runs from the meter or main shutoff to the house, or inside walls and ceilings. Finding the exact location without tearing out finished surfaces is what leak detection is for. This page covers both leak detection and slab leak repair, since they are usually the same job from different ends.

Seasonal homes deserve extra attention. If you are away for months, a small leak can run the whole time, so consider shutting off the main water when you leave.

Signs of a hidden or slab leak

A higher water bill with no change in use

A sudden or steady rise in water use that you cannot explain is the most common early sign.

The meter keeps moving when everything is off

Shut off all fixtures and appliances, then check whether the meter’s leak indicator or dial is moving. If it is, water is going somewhere.

Warm or hot spots on the floor

A leak in a hot water line under the slab can warm the floor above it.

The sound of running or hissing water

Water noise in a quiet house when nothing is in use suggests a pressurized leak.

Damp carpet, baseboards, cracked tile or musty odor

Moisture can appear at the surface long after a leak begins. Mold odor is a warning sign.

Low water pressure or wet areas in the yard

A leaking service line can reduce pressure or leave soggy ground between the meter and the house.

What the service can include

Locating the leak using acoustic listening, thermal imaging or pressure testing
Isolating the affected line and confirming the source
Spot repair by accessing the line through the slab
Rerouting the line overhead or through walls to bypass the slab
Repairing or replacing a leaking water service line
Documentation you may need for an insurance claim

Common causes and considerations

Pipe corrosion and pinholes. Copper lines under or in the slab can develop pinhole leaks, particularly as they age.
Abrasion and movement. Pipes rubbing against concrete or other materials as the building and ground shift.
High water pressure. Excess pressure stresses lines, fittings and fixtures.
Water chemistry. Mineral-heavy or aggressive water can accelerate wear on some pipes.
Age of the plumbing. Older lines are more likely to fail than newer ones.
Damaged service line. Excavation, ground movement or age can break the line between meter and home.

Slab leak repair options

The right repair depends on the pipe, the number of leaks and how accessible the line is. A provider may discuss:

Spot repair: opening the slab at the leak and repairing the line. Works well for a single, clearly located leak.
Rerouting: abandoning the leaking line and running new pipe through walls or the attic. Often considered when there are repeat leaks.
Repiping: replacing a larger run of plumbing when the lines are failing in several places.

Ask which method is proposed, what surfaces will be disturbed, how restoration is handled and what the warranty covers. Because slab leaks can involve flooring and structural work, check what your homeowner’s policy covers and consider notifying your insurer early.

What to do before you call

Shut off all water-using fixtures and appliances and check whether the water meter is still moving.
If the meter is moving, close the main water shutoff to the house and see whether the meter stops. This helps separate a leak in the house from one on the service line.
Note any warm spots, damp areas, odors or sounds, and take photos.
Keep copies of recent water bills so a provider can see usage over time.
If water is damaging the home, shut off the main and call right away.

What to check before hiring a provider

Providers reached through this site are independent. Before you agree to any work:

Ask for the provider’s Arizona Registrar of Contractors (ROC) license number and look it up on roc.az.gov to confirm status and license classification.
Ask whether they carry liability insurance and whether a permit is needed.
Get the price, what it includes and any warranty terms (parts and labor) in writing before work starts.
Ask who will perform the work and what happens if the repair does not fix the problem.

Frequently asked questions

How do I know if I have a slab leak?

Common signs are an unexplained spike in water use, warm spots on the floor, the sound of running water, damp flooring or low pressure. A provider can confirm with leak detection equipment.

Can a leak be found without breaking the slab?

Often yes. Acoustic, thermal and pressure-testing methods can narrow the location before any concrete is opened.

Is a water service line leak the same as a slab leak?

No. The service line runs from the meter or main shutoff to the house, and a leak there may show up as wet ground or low pressure. A slab leak is in lines under or inside the concrete foundation.

Is a slab leak an emergency?

If water is damaging the home or you cannot stop it, shut off the main valve and call. A slow leak is still worth addressing quickly, because it can keep wasting water and damage the structure.
