What are the signs of a hidden plumbing leak in my Cambridge home?

Shut off every fixture and appliance, then watch your water meter dial. If it's still moving, you have an active leak in the supply system. Other signals include unexplained spikes on your Region of Waterloo water bill, damp spots on walls or ceilings with no clear source, low water pressure at fixtures that used to flow well, mold growth along a baseboard, and the sound of running water when everything is turned off. Mold appearing near a wall or cabinet is a late sign and usually means the leak has been running for some time.

How does acoustic leak detection work?

Pressurized supply lines produce a specific sound profile when water escapes through a crack. Acoustic leak detectors amplify those frequencies through a sensor pressed to the ground or pipe surface and filter out background noise. Your plumber tracks the signal along the pipe path until it peaks, which marks the leak location. The method works through concrete slabs, compacted soil, and finished flooring, making it the standard approach for underground water mains and buried service lines. It's non-destructive and accurate enough to keep repair excavations small.

Can you detect leaks under a concrete slab?

Yes. Slab and underground leaks are among the most common calls we handle in Cambridge. Acoustic listening equipment pinpoints the leak through the slab before core drilling. Once confirmed, the repair opening stays as small as the job allows. For underground water mains, we trace the pipe with pipe tracing equipment, mark the repair location above ground, then dig only where needed.

How do I check if my toilet is leaking?

Add a few drops of food colouring to the tank and wait 15 minutes without flushing. If colour appears in the bowl, the flapper isn't sealing. A toilet that cycles on and off by itself is almost always a worn flapper. A hissing sound after the tank refills usually points to a fill valve that isn't shutting off fully. Both are straightforward fixes once you identify the worn part.

How We Locate Hidden Water Leaks in Cambridge

When water escapes through a crack or faulty fitting, it creates a distinct frequency that differs from normal flow. Acoustic leak detectors pick up that signal through concrete, soil, and finished flooring. Your plumber moves the sensor along the suspected line and narrows the leak location to within inches, keeping any repair opening as small as possible.
A pipe leaking behind drywall creates a cold spot that shows clearly on a thermal imaging camera, no wall cutting required. We use thermal imaging alongside acoustic profiling when the leak location isn't clear or when multiple problem areas are suspected. Catching a supply line leak before it saturates insulation or reaches the subfloor prevents the kind of structural damage.
For leaks that produce no audible signal, pressure testing isolates the problem. Our plumber shuts off the system, pressurizes the line, and monitors the drop. A slow pressure loss confirms an internal leak even when nothing is visible. Snake cameras are also used to inspect drain and sewer lines from inside, ruling out cracks or root intrusion in the sewer system as the source of water loss.
