Sewer backup clearing

When dirty water wells up through the basement floor drain, the main sewer line is blocked somewhere between your stack and the city connection at the street.

  • Stop the flow: ask everyone to stop flushing, running taps and using the washer
  • Find the access: locate the cleanout on the main drain, often beside the floor drain or under the stairs
  • Clear the line: run a cable auger with a cutting head out toward the property line
  • Look inside: push a camera through to see roots, breaks, sags or grease
  • Licensed plumbers (details on request)
  • Written job sheet
  • Pressure-tested repairs

01Two very different backups

There is the slow kind, where the floor drain gurgles for weeks and then overflows one morning after laundry. That is almost always a blockage in your own line: roots, a broken joint or years of grease. Then there is the sudden kind, during or right after a heavy rainstorm, where several houses on the street flood at once. That points to the city sewer surcharging, and the cure is a backwater valve rather than an auger.

Knowing which one you have saves money, so we always ask about the weather when you call.

Quick facts
Typical causeTree roots in clay laterals, grease build-up, collapsed or offset pipe
Storm-related backupsUsually point to an overloaded municipal sewer, not a blockage
Key protectionA backwater valve fitted to the building drain

02Roots and clay

Many Scarborough houses from the fifties and sixties were connected to the street with vitrified clay pipe in short lengths. The joints are where roots from boulevard maples and silver maples find their way in. Cutting them out gets the water moving, but they return, so we show you the camera footage and talk about lining or replacement.

03After the water goes down

Sewage is a health hazard. Keep children and pets away, wear gloves and boots, and throw out porous items that were soaked. Your home insurer may want photos before anything is removed.
