Common Signs of Hidden Plumbing Leaks

Hidden Leaks in Walls or Ceilings

Plumbing leaks inside walls or ceilings often reveal themselves through bubbling paint, soft drywall, staining, musty odors, or recurring mold. Because water can travel along framing, visible damage may not be near the actual leak. Professional detection helps identify whether the source is a supply line, drain line, or fixture connection without unnecessary demolition.

Signs of a Slab Leak

Slab leaks occur beneath the concrete foundation and can impact flooring, air quality, and structural stability. Common indicators include unexplained water usage spikes, warm spots on floors, damp carpet, cracked tile or grout, and the sound of running water when fixtures are off. Reduced water pressure can also be a red flag. Early detection helps minimize disruption and repair costs.

How Plumbing Leak Detection Works

Non-Invasive Detection Methods

We use a combination of acoustic listening equipment, moisture mapping, pressure testing, and line isolation to confirm where water is escaping. Acoustic technology detects the distinct sound of pressurized water leaking from pipes, while additional testing validates results and narrows the location.

Can Leaks Be Found Under Concrete?

Yes. Acoustic equipment and pressure testing allow leaks under concrete slabs or underground supply lines to be located with a high level of precision. This approach helps avoid breaking concrete in the wrong area and reduces overall restoration time.

High Water Bills and Service Line Leaks

What Causes Sudden High Water Bills?

A sudden increase in water usage is often caused by hidden plumbing leaks, leaking toilets, irrigation issues, or a compromised water line between the meter and the house. Checking the water meter with all fixtures off is a helpful first step, but professional detection provides definitive answers.

Detecting Leaks Between the Meter and the House

Service line leaks may not surface visibly and can drain directly into soil. Professional leak detection traces the line path and identifies the leak location without unnecessary trenching, protecting landscaping, driveways, and walkways.

Advanced Plumbing Leak Testing

Hydrostatic Plumbing Testing

Hydrostatic testing is used to evaluate drain and sewer systems for leaks by isolating and filling lines with water to monitor pressure loss. It’s often recommended when there are recurring sewer odors, suspected under-slab drain leaks, or unexplained moisture near bathrooms.

Detecting Leaking Toilets

Toilets are a common source of silent water loss. A simple dye test can confirm whether water is leaking from the tank into the bowl. If the issue extends beyond a single fixture, professional leak detection can rule out larger plumbing problems.
