Repiping for Aging & Failing Plumbing Systems
When pipe problems are no longer isolated, repeatedly repairing one section at a time may not solve the underlying issue. Proflow provides repiping solutions for homes and businesses across British Columbia.
Sometimes the problem is the piping system itself.
One leaking fitting or damaged section may only need a localized repair. But recurring leaks, aging materials and deterioration across different areas can indicate that a broader piping replacement should be considered.
Look at the pattern, not just the latest leak.
Repeated Pipe Leaks
Leaks appearing in different areas of the plumbing system can suggest deterioration beyond one damaged section.
Aging Pipe Material
Older piping may become increasingly vulnerable to leaks, deterioration and connection failures.
Visible Corrosion
Widespread corrosion or mineral buildup can indicate that sections of the water piping are deteriorating.
Water Pressure Problems
Changes in flow or pressure can sometimes be associated with restrictions or deterioration within older plumbing.
Previous Repairs
A history of repairs throughout the property may make continued spot repairs less practical.

Repiping is different from repairing a pipe.
Pipe repair focuses on a specific damaged section. Repiping looks at a larger part of the water distribution system and replaces piping where continued localized repairs may no longer be the appropriate approach.
Replacing piping starts with understanding the existing system.
A repiping project should be based on the condition and layout of the property—not simply replacing pipes without understanding why failures are occurring.
Assess
Review existing piping, problem areas, materials and the history of plumbing failures.
Plan
Determine which sections require replacement and how new water lines can be routed through the property.
Replace
Remove or bypass affected piping and install the planned replacement water lines and connections.
Test
Check the completed plumbing system, connections and water delivery before the project is considered complete.
The replacement system depends on the property.
The appropriate piping material and layout depend on the building, existing plumbing, accessibility and project requirements.
Flexible Water Distribution
PEX is commonly used in modern residential water distribution systems and can be routed through building framing with fewer rigid connections.
Traditional Water Piping
Copper remains an established plumbing material and may be appropriate depending on the property and installation requirements.
Have Poly-B plumbing?
Poly-B is found in many older properties and deserves its own assessment when planning plumbing replacement. If your property has Poly-B piping, learn more about our dedicated Poly-B Replacement service.
Poly-B replacement is a specific type of repiping focused on replacing existing Poly-B water distribution piping.
What can a repiping project involve?
The exact scope depends on the property and the sections of plumbing being replaced.
Common questions about repiping
Does one leaking pipe mean my home needs repiping?
No. A single isolated failure may only require pipe repair. Repiping is generally considered when the condition or history of the plumbing indicates a broader system problem.
Can only part of a property be repiped?
Depending on the condition and layout of the plumbing, replacement may involve selected sections rather than the entire property. The appropriate scope requires assessment.
What type of pipe can be used for repiping?
Replacement materials can include PEX, copper and other appropriate plumbing materials. The choice depends on the property, existing system and project requirements.
Is repiping the same as Poly-B replacement?
Poly-B replacement is a specific type of repiping involving Poly-B plumbing. General repiping can involve several different existing pipe materials and plumbing conditions.
