Kitchen Plumbing for Homes Across the GTA

Kitchens pack a lot of plumbing into one cabinet: a sink, a drain with a trap and vent, supply lines, a dishwasher, often a disposer and a fridge water line.

  • Trap and supply lines rebuilt under the fixture
  • No-leak check with water running
  • Old fixture hauled away on request

Signs it is time to call

New sinks and faucets, dishwasher installs, disposers, fridge lines, relocated sinks during a renovation and leaks in the sink cabinet all fall here. Moving a sink to an island is the biggest job, because the drain needs slope and venting under the floor.

Most kitchen leaks live in the back corner of the sink cabinet, behind the cleaning bottles.

On the job, step by step

  1. Shut off and inspect the existing stops and trap.
  2. Fit the sink and faucet, then the drain assembly with a properly sized trap.
  3. Connect the dishwasher discharge with an air gap or a hose looped up under the counter so dirty water cannot siphon back.
  4. Install a disposer on a dedicated outlet where wiring exists.
  5. Run the fridge line with a separate shut-off.
  6. Test everything under load: full sinks, a dishwasher cycle, disposer running.

GTA houses and what they change

Island sinks need a drain route through the floor and either a loop vent or an air admittance valve where allowed. Old galvanized drains in the wall may be too narrow for a modern double sink with a disposer. Condo kitchen moves are often limited by stack locations.

  • Air gap or high loop on the dishwasher drain
  • Separate shut-off for the fridge
  • Trap arm slope checked

Common questions

Does relocating the sink need a permit?

Moving drains and vents generally requires a plumbing permit. Replacing a sink in the same location usually does not.
