Step Test Sectoring

When the question is "which zone of the network is losing water," step testing is the right answer. By systematically closing valves and watching flow at a central meter, we isolate the zone containing active leakage, then progressively narrow to specific main segments before deploying acoustic methods on the suspect section. This is the workhorse method behind utility-scale leak reduction programs, and it scales from a small commercial property's loop to a municipal district metered area.

Why Acoustic Water Leak for step test sectoring

Acoustic Water Leak 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.

Pairs well with

Clients booking step test sectoring 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).
