Hydrophone Inspections

Large-diameter and long-run transmission mains often defeat surface acoustic methods — the signal simply doesn't reach the surface clearly enough. Insertable hydrophone arrays attach inside the line through existing fittings and tow through the main, capturing the leak signature directly inside the water column. We perform these inspections for water utilities and industrial facilities with mains too long, deep or large for conventional correlation. Deliverables include the leak locations on a referenced site plan plus the raw acoustic data for engineering review.

Why Acoustic Leak Detection for hydrophone inspections

Acoustic Leak Detection is a sub-division of Leak.ca, the Greater Vancouver leak detection company trusted since 1999. Every site visit is delivered by certified technicians using calibrated equipment, with documented findings formatted for insurance, engineering and procurement use.

We don't sell remediation. Our role is independent detection and assessment — the data you and your professional team work from.

Pairs well with

Clients booking hydrophone inspections often combine it with Acoustic Leak Correlation or Ground Microphone Surveys — particularly when the underlying issue spans multiple systems or when documentation needs to support a broader investigation.

How to prepare for your visit

1. Document what you're seeing. Photos, dates, sounds, water-bill changes, anything unusual. The more we know in advance, the faster we can locate.
2. Clear access to the suspected area. Move furniture, stored items, and rugs. Non-invasive methods still need clear sightlines.
3. Have system history ready. Recent plumbing work, prior leaks, renovations, age of property, prior insurance claims.
4. Confirm the email for your report. Photo-linked report delivered within 48 hours (often same-day for residential).
