Basement floor drain backups in North York

Of every drain in the house, the floor grate sits deepest. When anything downstream blocks, water comes out there first. That makes it the best early warning you have.

What it usually means

Water at the floor drain once the washer empties points to a blockage between the drain and the city sewer. Water there during a heavy storm, with nobody running a tap, points to the city sewer surcharging or a cracked lateral taking on groundwater.

  • Grey water pooling after the washer pumps out
  • Sewage smell in the laundry room
  • Water that appears during rain and drains away after
  • Dry drain with a sewer odour, which means the trap has evaporated

How we sort it out

First the plumber finds the main cleanout, typically low on the street-facing wall where the sewer leaves the house. If water is standing in the cleanout, the blockage is further out, toward the street. A drum machine with a cutting head goes in there and runs out the lateral. Roots, wipes and grease are the common catches.

If the cleanout is dry and only the floor drain is blocked, we cable the floor drain itself. Older North York houses often have a clay or cast iron trap under that grate packed with sand and lint from years of washer water.

After it is clear

We suggest a camera run after any main line backup. It shows whether roots came through a joint, a section sagged or the pipe cracked. That decides between a yearly clearing and a repair. If the backup came from the city side during a storm, a backwater valve is what blocks the next one.

Dry trap smell? Pour a bucket of water down the floor drain every month or two. A spoon of mineral oil on top slows evaporation.

While you wait for us

  1. Stop the washer, dishwasher and showers.
  2. Shift rugs and storage boxes clear of the grate.
  3. Keep kids and pets off the wet patch; treat it as sewage.
  4. Take photos for your insurance company.

Questions

Should I remove the floor drain grate?

Only if it lifts easily. Do not chip concrete around it. We bring tools to open it properly.

Does insurance cover a floor drain backup?

That depends on whether your policy has sewer backup coverage. Call your insurer and check; many require it as an add-on.
