Vertical Riser & Plumbing Leak Detection
Detecting shared plumbing failures between floors using advanced acoustic and thermal technology — minimizing disruption while delivering precise, insurance-grade results.
Riser Plumbing Failures in Strata Buildings
Vertical plumbing risers are among the most critical — and vulnerable — components of a strata building's shared infrastructure. These pipes run through common-property pipe chases connecting every floor, carrying domestic water supply, drainage, and in some buildings, fire suppression water. When they fail, the impact can span multiple units across multiple floors, creating urgent situations that require both rapid response and precise documentation.
Riser failures are particularly challenging because they are hidden within walls and pipe chases, making visual inspection impossible without destructive exploration. StrataLeak.ca's advanced acoustic and thermal detection methods allow us to locate failures accurately before any walls are opened, protecting the building and its residents from unnecessary disruption.
Types of Riser & Shared Plumbing Failures
Pressurized Supply Riser Failures
Failures in hot or cold water supply risers release pressurized water continuously until the system is shut down. Even minor pinhole leaks in copper or galvanized supply pipes can saturate wall and floor assemblies over days or weeks before being detected. These failures are the most urgent and require immediate response.
Drain Stack & Sanitary Riser Leaks
Failures in drain stacks occur at pipe joints, couplings, and cleanout access points. These failures are intermittent — they leak during periods of high usage — making them more difficult to detect. Drain riser failures can introduce sewage contamination into wall assemblies, requiring both leak detection and biohazard remediation.
Aging Copper Pipe Failures
BC strata buildings from the 1970s and 1980s frequently have original copper plumbing approaching or past its service life. Pinhole corrosion, dezincification of brass fittings, and failed solder joints are common in aging systems and can occur simultaneously in multiple locations throughout the building.
Galvanized Steel Pipe Deterioration
Older buildings with galvanized steel supply pipes experience internal corrosion that eventually causes pinhole leaks and fitting failures. Galvanized pipe failures often indicate the supply system is approaching end-of-life and a comprehensive riser replacement program should be considered.
Recirculation & Hot Water System Leaks
Central domestic hot water recirculation systems keep hot water available at all units, but the recirculation pump, fittings, and flexible connections are frequent failure points. Recirculation leaks are continuous (not intermittent) and can cause significant damage before they are discovered.
Our Riser Leak Detection Methods
Acoustic Leak Detection
Specialized listening devices detect the pressure signature of water escaping from supply pipes within walls, ceilings, and pipe chases — locating failures without opening any surfaces.
Thermal Imaging
Infrared cameras detect temperature anomalies caused by hot or cold water leaking within building assemblies, tracing the thermal signature back to the pipe failure point.
Moisture Mapping
Systematic moisture meter readings across multiple floors map the distribution of water damage and identify which floor levels are most affected, narrowing the probable failure zone.
Pressure Testing
When appropriate, isolated pressure testing of pipe sections confirms the location of failures and quantifies system integrity before repair decisions are made.
Common Property Considerations
In BC strata buildings, vertical risers within common property pipe chases are typically maintained by the strata corporation. However, the horizontal branch lines that connect risers to individual unit fixtures are generally the unit owner's responsibility. The exact boundary between common property and owner-maintained plumbing is defined by the strata plan and bylaws.
Our investigation reports identify the precise failure location and characterize it as either within the common riser system or within a unit-specific branch. This clear determination is essential for assigning repair costs and insurance claims correctly under the Strata Property Act.
Service Areas
Riser and plumbing leak detection services are available throughout Metro Vancouver and BC, including Vancouver, Burnaby, Richmond, Surrey, Coquitlam, North Vancouver, West Vancouver, New Westminster, Delta, Langley, and surrounding communities.
Frequently Asked Questions
What is a plumbing riser in a strata building?
A vertical plumbing riser is a main supply or drain pipe that runs vertically through a strata building, serving multiple units on multiple floors. Risers carry domestic hot and cold water, drainage, or fire suppression water. Because they pass through common property pipe chases, leaks in risers affect multiple units and are typically the strata corporation's maintenance responsibility.
How do you detect a riser leak without opening walls?
We use acoustic leak detection equipment that listens for the pressure signature of water escaping from supply pipes, combined with thermal imaging to detect temperature anomalies caused by hot or cold water leaking within wall and ceiling assemblies. This allows us to pinpoint the approximate leak location before any exploratory work is authorized, minimizing unnecessary disruption.
How many floors can a single riser leak affect?
A single riser leak can affect anywhere from one to every floor in the building, depending on where the failure occurs within the pipe run and how long it has been active. Water from a pressurized supply pipe failure near the top of a building can saturate multiple floor assemblies before appearing as visible damage. Drain riser failures typically cause localized damage but can affect all units connected to the same stack.
Who pays for riser leak repairs in a strata?
In most BC strata corporations, vertical risers are common property and are therefore the strata corporation's responsibility to maintain and repair. However, horizontal branches within individual units are typically owner-maintained. Our investigation clearly identifies whether the failure is in the common riser or a unit-specific branch, providing the documentation needed to assign costs correctly.
