Acoustic leak detection explained in plain English

Acoustic leak detection is one of the primary tools Straight Flush Plumbing uses to locate hidden water leaks. Instead of opening walls or cutting concrete first, we use calibrated listening equipment to hear the sound signature of water escaping under pressure.

What the equipment actually hears

A pressurized leak produces a continuous high-frequency hiss that is different from normal pipe flow. Sensors and amplifiers pick up that signature through floors, walls, and soil so the technician can narrow the location to a small zone.

Why it matters for South OC homes

Many Laguna Niguel, Mission Viejo, and Dana Point homes sit on expansive clay soils and still have original copper lines from the 1970s–90s. Hidden slab leaks are common. Acoustic methods let us confirm the leak location before any concrete is opened — which is the entire point of diagnose-first plumbing.

What to expect on a visit

• We discuss symptoms (bill spikes, warm spots, running-water sounds).
• Pressure testing isolates the affected line.
• Acoustic and complementary methods (electronic, thermal) pinpoint the spot.
• You get clear findings and options — no pressure to proceed.
