Clogged drains are one of the most common (and annoying) plumbing issues homeowners face. Whether it’s a slow-draining sink or water backing up into your shower, it often starts small and then turns into a big problem.
Understanding what causes a drain blockage in the first place is the first step to preventing it. At Caldwell Plumbing, we’ve been helping homeowners in Pickering and across the Durham Region fix and prevent clogged drains since 1979. Here’s what you should know to keep your pipes flowing.
What Causes a Clogged Drain?
Everyday habits are often the reasons behind a blocked drain. Even small things, like rinsing cooking grease or letting hair collect in the tub, can add up to major blockages over time. Here are the most common causes we see:
- Grease and fat: These solidify as they cool, coating the inside of your pipes.
- Hair: Often combined with soap to create tough tangles in shower and sink drains.
- Soap scum: Especially from bar soaps, this builds up along pipe walls and traps other debris.
- Food scraps: Coffee grounds, eggshells, and fibrous foods don’t break down easily and can jam your drain.
- “Flushable” wipes: Despite the name, these don’t break down like toilet paper and can clog toilets and sewer lines.
- Tree roots: Roots can grow into tiny cracks in sewer lines and cause major backups.
Mineral buildup: In older homes with hard water, minerals can narrow pipes and slow drainage.
How to Prevent Drain Blockages in Your Home
Most clogged drains are preventable with simple habits and occasional maintenance. Try these tips to prevent drain blockages in your home to avoid the need for emergency plumbing services:
- Use drain screens: Catch hair and debris in showers, tubs, and kitchen sinks.
- Dispose of grease properly: Pour it into a container and throw it out, never down the drain.
- Compost or toss food scraps: Even with a garbage disposal, large bits can clog pipes.
- Avoid flushing anything but toilet paper: Wipes, feminine hygiene products, and cotton balls can all cause a drain blockage.
- Use enzyme-based drain cleaners occasionally: These help break down organic buildup without harming your pipes.
- Schedule routine inspections: A plumber can spot early warning signs before they become major issues.
- Know where your cleanout is: Knowing where this access point is on your main drain makes emergency service faster and less disruptive.
When to Call an Emergency Plumber
Sometimes a slow drain is annoying, but in other cases, it’s the sign of a serious plumbing problem. Here’s when you should skip the DIY drain cleaning methods and call a licensed emergency plumber:
- Multiple fixtures are backed up: This often means there’s a blockage in your main sewer line.
- Toilets won’t flush: Especially if plunging doesn’t help or water backs up elsewhere.
- Standing water in your basement: This could point to a floor drain or sewer backup.
- Bad smells from your drains: Especially if they smell like sewage or rotten food.
- Gurgling sounds in pipes: A sign of air trapped by a clog somewhere in the system.
