What Causes Drain Backups?

Understanding what causes backups can help you prevent future incidents. Here are the most common culprits:
plumbing

Grease, Hair & Debris

Grease from cooking, hair from showers, and debris from sinks all build up over time. These substances harden and narrow the pipes, eventually blocking the flow of wastewater. Regular maintenance and avoiding the practice of pouring grease down the drain can prevent this issue.

Tree Roots in Sewer Line

Roots from nearby trees can enter cracks in your sewer line, growing over time and blocking the pipe. This is a leading cause of sewer backups and requires specialized root removal tools, as well as trenchless repair. Tree root intrusion is more common in older neighbourhoods with clay pipes or aging infrastructure.

Collapsed or Bellied Pipes

Pipes can shift, sag, or collapse due to soil movement, age, or poor installation. These physical obstructions cause water and waste to collect in one spot, eventually backing up into your home. Identifying these issues early through camera inspection can save you from emergency plumbing situations.

Improper Slope or Flow

If your plumbing system doesn't have the proper slope, wastewater won't drain properly. This can lead to standing water and recurring backups, especially in basements or lower-level drains. Any home renovations involving plumbing must adhere to proper building codes and grading guidelines.

Flushing Non-Flushables

Items such as wipes, feminine hygiene products, paper towels, and dental floss don't break down in water. When flushed, they cause clogs deep within your pipes and sewer system. Educating household members and placing visible reminders in bathrooms can reduce the risk of blockages.

Signs You Have a Backup

Drain backups often exhibit warning signs before a full-blown flood occurs. Here’s what to watch for:
1

Water Coming Up From Drains

One of the most evident signs of a backup is water bubbling up from a drain you’re not using. This often happens in tubs, basement drains, or showers. It indicates pressure building up from a blockage further down the line.
2

Multiple Drains Clogged at Once

If more than one drain in your home is backing up or slow, the issue is likely in the main sewer line. This requires immediate attention from a plumbing expert. Ignoring this sign could lead to significant water damage and contamination.
3

Gurgling Toilets or Showers

Gurgling noises when you flush or run water indicate air trapped by a clog. This is a sign that wastewater is having trouble passing through your plumbing system. These sounds are often the first hint that a backup is forming.
4

Foul Odours

Unpleasant sewer smells inside your home are a red flag. It usually means there’s a blockage or leak in your drainage system. Odours may come and go at first, but they will worsen if left unresolved.
5

Slow Drainage Everywhere

If all your drains are moving slowly, it’s likely a sign of a partial blockage in your main line. Please don’t wait for it to turn into a full backup. A slow-drain scenario is often your best chance to intervene before a significant issue occurs.
