Hydrostatic Pressure Testing in British Columbia
Before locating a leak precisely, it often helps to confirm one exists and isolate which system is failing. Hydrostatic pressure testing seals and pressurizes a plumbing or drainage system and monitors whether it holds — a controlled, definitive way to prove integrity or expose a hidden leak.
Leaks.ca is the educational leak detection hub and service-support division of Leak.ca, helping BC property owners understand leak risks and connect with professional detection services when needed.
Hydrostatic pressure testing isolates a supply, drainage or mechanical system, applies controlled pressure (water or air), and monitors for a pressure drop that confirms a leak. By testing systems and zones in sequence, it narrows the failure to a specific run before acoustic, tracer-gas or camera methods pinpoint the exact source — essential for sewer and drainage lines that don't carry pressure in normal use.
- Suspected but unconfirmed leaks on supply or drainage systems
- Cracked or broken sanitary and storm drainage under slabs
- Sub-slab and below-grade line failures
- Pre-purchase and pre-renovation system-integrity checks
Why It Matters
Definitively confirms whether a leak exists
Isolates the failing system before precise location
Tests non-pressurized drainage that other methods can't
Hydrostatic Pressure Testing — FAQ
It confirms whether a plumbing or drainage system holds pressure. By isolating and pressurizing systems in sequence, it proves integrity or exposes a hidden leak and narrows it to a specific run — particularly valuable for sanitary and storm drainage, which carry no pressure in normal use.
No — it confirms and isolates a leak; it doesn't pinpoint the exact spot. Once a test identifies the failing system, acoustic detection, tracer gas or camera inspection locates the precise source so the repair is targeted.
