Commercial plumbing

Riser, stack and booster work in condo and rental blocks

In a stacked building one suite’s problem is rarely only one suite’s problem. A kitchen stack blocked on the fourth floor backs up into the third, and a weeping riser valve can stain ceilings two levels down.

  • Stack blockages cleared from the right cleanout
  • Riser valves and in-suite stops turned, swapped if seized
  • Pressure-reducing and booster set-ups checked
  • Suite leaks traced through ceilings with minimal openings
  • Shut-downs planned with notice to residents

Stacks and shared drains

  • Every suite above pours its frying-pan residue into one shared kitchen stack, and it hardens on the way down. Once the bottom unit sees its sink fill, we open a cleanout at or below that floor and work the cable or jet head through both directions. Going in from the roof vent is possible in some towers, but it tends to shove the plug deeper into any sideways offset.
  • Laundry and washroom stacks fill with lint and hair. We camera them after clearing so the board or manager has a picture of the pipe condition, not just a receipt.

Risers, valves and water pressure

  • Many low-rise condos and townhouse blocks rely on a handful of gate or ball valves to isolate risers. Old gate valves seize and never fully close. We exercise them, replace the ones that fail and label what each controls, so the next leak does not mean shutting down the whole building.
  • Taller buildings use booster pumps and pressure-reducing valves. When upper floors lose pressure at peak hours or lower floors see banging pipes, those devices are the first things we check.

Signs you need this

  • Water coming up in a lower suite’s sink
  • Ceiling stains below a bathroom or kitchen
  • Upper floors losing pressure in the morning
  • Riser valves nobody dares to close
  • Banging pipes when a fixture shuts off

Working with residents

  • Any water shut-down is planned with notice posted for residents. We confirm which suites are on the riser before closing anything.

How the job runs

  1. 1

    The manager or board calls with the address and symptoms.

  2. 2

    We check drawings or walk the building to find risers and cleanouts.

  3. 3

    Residents are notified before any shut-down.

  4. 4

    Repair is made, lines are flushed and pressure checked.

  5. 5

    A short report with photos goes to the manager.

For businesses: tell us your trading hours, the number of fixtures and where the cleanouts are, if you know. It lets us book the visit when it disrupts the least.
