Pressure testing is at its most useful in three situations: confirming that an existing buried line is or is not the source of a known leak; verifying that a recent repair has held; and grading old supply lines as part of a renovation or pre-purchase inspection.

It is the test of choice when an insurer, certifier, or council needs an objective confirmation that a section meets standard.

We deploy pressure testing as the verification step after detection — confirming that the section we've located is in fact the source of the leak, and that the rest of the line is sound. We also use it to certify completed repairs for compliance handover.

On older properties or commercial sites, a pressure test is sometimes the only practical way to grade an entire run before deciding whether to reline or replace.

Pressure testing is the most procedural-feeling part of any inspection — there's a gauge, a regulator, an isolation routine, and a recorded test window during which the technician monitors the pressure decay.

During the test the line is offline, which usually means an interruption to water supply for the duration. We coordinate timing so the interruption is brief and predictable.

A pressure test is the only piece of evidence that says "this section is sound" or "this section is not" without ambiguity. Detection finds the leak; pressure testing confirms it. Together, the two close out a job with no open questions.

For insurance burst-pipe claims, certifying pressure-test reports are standard supporting documentation. We supply a template-compliant report that meets each major insurer's requirements.
