How To Clear A Blocked Drain Without Chemicals

Blocked drains are an annoying problem that every homeowner dreads. They disrupt our daily routines and have the potential to cause serious water damage.

The go-to solutions tend to involve harsh chemicals, but there are greener and safer ways you can consider first. Clearing drains without chemicals can protect our environment from harmful substances and extend the life of your pipes, preventing corrosion and leaks.

Let’s explore how you can tackle blocked drains without reaching for the chemicals.

Signs of a Blocked Drain

Noticing the early signs of a blocked drain can save you from bigger plumbing problems down the line.

Here’s what to look out for:

  • Slow Drainage: Water pooling around your feet in the shower or a sink that takes forever to empty? That’s a blockage problem.
  • Backups and Overflow: When water backs up instead of flowing down the kitchen or bathroom sink or the toilet, it’s a red flag.
  • Unpleasant Odours: Foul smells from your drains are usually caused by food, grease, or hair decomposing in your pipes.
  • Overflow: Water spilling over the edge of your sink or toilet bowl indicates a serious clog that demands immediate attention.

Non-Chemical Methods to Unclog Drains

Clearing a drain doesn’t require harsh chemicals. Simple household supplies like hot water, baking soda, and vinegar can do the trick!

Hot Water

Start by boiling a kettle of water. This method works well for grease build-up because it melts the grease clog into a liquid so that it can be washed away.

Baking Soda

Next, pour a cup of baking soda directly into the drain. Baking soda is a great cleaning agent that helps dislodge the gunk stuck in your pipes.


Follow the baking soda with a cup of white vinegar. The combination creates a fizzing reaction that can break down the residue inside your pipes.

After pouring the vinegar, cover the drain with a plug to keep the reaction below the surface and maximise its cleaning power.

Wait for about 15–30 minutes, then flush the drain with another kettle’s worth of boiling water to clear out the mixture along with the loosened gunk and debris.

This simple, eco-friendly method can effectively handle and prevent clogs without damaging your pipes or the environment.

Preventative Maintenance

Keeping your drains clear and odour-free doesn’t have to be a chore. Regular maintenance can prevent the build-up of gunk and wastewater.

Here are some methods to keep your pipes flowing smoothly:

  • Regular Flushing: Once a week, pour boiling water down your drains. This can help melt away any grease or soap build-up before it becomes a blockage.
  • Baking Soda and Vinegar: Use the baking soda and vinegar method every 1–2 months. This will keep your pipes and drains clear and neutralise any bad smells.
  • Catch It Early: Use sink strainers to catch hair, food particles, and other debris. This simple step can greatly reduce the risk of clogs.

By using these easy maintenance tips in your cleaning routine, you can avoid blocked drains and maintain a healthy plumbing system without harsh chemicals.

Helpful DIY Plumbing Tools

Tackling simple blockages at home doesn’t always require a plumber’s toolbox. With a few basic tools that you can easily find at your local hardware store, you can manage most minor clogs with ease.


  • What Is It? There are two main types of plungers:
    The common sink plunger with a flat cup that is designed for flat surfaces.
    The toilet plunger (which has a flanged bottom to fit into the toilet bowl).
  • Use: For effective use, make sure the plunger has a tight seal over the drain. Apply forceful thrusts to dislodge the blockage. The sink plunger is perfect for kitchen sinks and bathtubs, while the toilet plumber is — you guessed it — designed specifically for the toilet.

Drain Snake

  • What Is It? A manual drain snake that reaches deep into pipes to remove clogs beyond the reach of plungers.
  • Use: Feed the snake into the drain until you encounter resistance, then twist to catch and pull out the source of the blockage.

Hose-End Bladder

  • What Is It? This tool attaches to a garden hose and uses water pressure to clear blockages.
  • Use: Insert the bladder into the clogged drain and turn on the water. The bladder expands and forces water pressure through the blockage.


  • What Is It? Toilet augers are a type of drain snake designed for toilets. They have a protective sleeve to prevent porcelain scratches.
  • Use: They’re more effective for clogged toilets, reaching deeper with a curved design to navigate the bends of the toilet.

Understanding Pipe Relining

Pipe relining is a revolutionary, no-dig solution for repairing damaged sewer lines and effectively preventing future blockages, all with minimal disruption to your property.

No-Dig Convenience

This method involves inserting a durable liner inside your home’s existing pipes. The liner hardens to form a new, seamless pipe within a pipe.

This process eliminates the need for excavation, preserving your backyard, garden, and driveway while fixing the problem at hand.
