What Causes Sewer Backups

A sewer backup is one of the worst plumbing emergencies a homeowner can face. Raw sewage flooding into your basement creates health hazards, destroys property, and costs thousands to clean up. Understanding what causes sewer backups helps you take preventive measures to protect your home.

Golding Plumbing has been preventing and resolving sewer backup issues for Durham Region homeowners for over 30 years. Here's what you need to know.

Tree Root Intrusion

Tree roots are the most common cause of sewer backups in Durham Region. Roots naturally seek out moisture and nutrients, finding their way into sewer lines through tiny cracks and joint separations. Once inside, they grow rapidly, creating blockages that trap waste and cause backups.

Regular sewer line inspection and root removal can prevent root-related backups. For persistent problems, pipe lining or replacement may be necessary.

Aging or Damaged Pipes

Older homes in Pickering, Ajax, Whitby, and Oshawa may have clay or concrete sewer pipes that deteriorate over decades. Cracks, breaks, and joint separations allow soil to enter the pipe, creating blockages. Pipe bellies (sagging sections) also trap waste.

Video camera inspection reveals the condition of your sewer line and helps determine whether repair or replacement is needed. Call (416) 669-8327 for a sewer line inspection.

Grease and Debris Buildup

Grease, wipes, feminine products, and other items that shouldn't be flushed gradually build up in sewer lines. Combined with soap residue and mineral deposits, these materials create stubborn blockages that lead to backups.

Only flush human waste and toilet paper. Keep grease out of your drains. Professional hydro jetting can remove existing buildup and restore full sewer flow.

Municipal Sewer System Issues

Sometimes sewer backups are caused by problems in the municipal sewer system rather than your private line. Heavy rainfall can overwhelm the system, and main line blockages can cause sewage to back up into homes.

A backwater valve prevents municipal sewage from entering your home. Many Durham Region municipalities offer rebates for backwater valve installation. Golding Plumbing installs backwater valves throughout the region.

Prevention Is Key

The best defense against sewer backups is prevention. Install a backwater valve, have your sewer line inspected every few years, avoid putting grease and non-flushable items down your drains, and address tree root issues promptly.
