Pinhole leak in corroded copper main shuts down hot water to 6-storey Richmond condo
Corrosion on a 4" copper domestic hot water main led to a pinhole leak, forcing a full shutdown of hot water to this 6-storey condo building — not a small inconvenience with that many residents affected.
Our techs drained the system down and cut out the corroded section of pipe along with the ball valve, which had corroded along with it. Repaired the piping and got everything reconnected and pressure tested.
System's back up and supplying hot water to residents again.
Corrosion on older copper mains doesn't always announce itself until it fails outright — worth keeping an eye on if your building's domestic hot water piping is getting up there in age.
