01Problems we see in east-end buildings
Older rental slabs and mid-rise condos share a familiar list:
- Shut-off valves on risers that have not turned in decades and will not close
- Pinholes in copper branches feeding kitchens and bathrooms
- Cast-iron drain stacks cracking or leaking at hubs
- Laundry room drains overloaded by modern high-volume machines
- Booster or sump pumps short-cycling or failing in the garage
| Common failures | Seized riser valves, pinhole copper branches, cracked cast-iron stacks |
|---|---|
| Who decides | The condo declaration sets what is unit-owned and what is common element |
| Usual access | Suites above and below, the mechanical room and the garage level |
02Working in an occupied building
A building is dozens of households who did not ask for a plumber. Before water goes off we confirm with management which risers feed which suites, post notice, and plan the shutdown so it is as short as possible. Working in someone else's home means drop sheets, small openings and an explanation for the resident, not just the manager.
Where a leak crosses suites, the job sheet records exactly where the water came from. That matters to the corporation, the owners and their insurers when they sort out who pays.
03Planned work beats emergencies
Many buildings call only when a ceiling is dripping. A planned round of valve exercising, replacing the ones that fail to close, means a future leak stays confined to a single stack instead of the whole building. The same goes for scoping the main drain from the garage cleanout before a backup, not after it.
