4 Simple and Safe Tips for Unblocking Drains at Home

Blocked drains are a common issue in many households, leading to slow water drainage, unpleasant odours, and potential plumbing damage if not addressed. While some minor blockages can be managed with simple, safe, and environmentally friendly DIY solutions, others may require professional intervention. This article explores four effective methods for clearing blocked drains at home and provides guidance on when it’s necessary to call a licensed plumber for expert assistance.

Common Causes of Blocked Drains

Blocked drains can occur due to various factors, including:

  • Hair and Soap Scum: Accumulated hair and soap residue in bathroom sinks and showers. Over time, these materials bind together, forming clogs that restrict water flow.
  • Grease and Food Scraps: Oils, fats, and food particles can solidify and clog kitchen sinks. These substances tend to adhere to the inner walls of pipes, gradually narrowing the passageway for water.
  • Foreign Objects: Items like wipes, sanitary products, or small household objects mistakenly flushed down toilets. Unlike toilet paper, these materials do not break down easily and can cause significant blockages.
  • Tree Roots: Invasive roots from nearby trees can penetrate underground pipes, causing blockages. Roots seek moisture and nutrients, often finding their way into small cracks in sewer lines and expanding over time.


Identifying the cause of a blockage helps determine the best approach for clearing it effectively. Understanding these common culprits can also help homeowners take preventative measures to keep their plumbing systems functioning optimally.

1. Use Boiling Water

Boiling water is a simple yet effective solution for minor drain blockages, especially those caused by grease and soap buildup. The heat dissolves the hardened substances, allowing water to flow freely.

How to Use:

  • Boil a kettle of water.
  • Slowly pour it down the drain in two to three stages, allowing it to work through the blockage.
  • Wait a few minutes, then run warm water to check if the blockage has cleared.


Best Used For:

  • Kitchen sinks clogged with grease and food residue.
  • Bathroom sinks with minor soap scum buildup.
  • Regular maintenance to prevent blockages.


Safety Tip: Avoid using boiling water on PVC pipes, as extreme heat can cause damage. If you’re unsure about your plumbing materials, opt for warm water instead.

2. Use a Plunger

A plunger is a useful tool for dislodging stubborn clogs by creating suction and pressure. It is one of the most effective manual methods for clearing blockages in sinks, showers, and toilets.

How to Use:

  • Ensure there is enough water in the sink or toilet to cover the plunger’s cup.
  • Position the plunger over the drain and push down firmly.
  • Perform quick, strong plunges for about 30 seconds.
  • Check if the water starts draining. Repeat if necessary.


Best Used For:

  • Sinks, bathtubs, and showers with standing water.
  • Toilets with minor blockages.


For best results, use a separate plunger for toilets and sinks to maintain hygiene. If a plunger does not work, it may indicate a more severe blockage that requires additional intervention.

3. Try a Baking Soda and Vinegar Solution

This natural, chemical-free method helps break down organic debris within the pipes. The reaction between baking soda and vinegar produces a fizzing action that can loosen clogs and remove built-up grime.

How to Use:

  • Pour half a cup of baking soda into the drain.
  • Follow with one cup of vinegar.
  • Let the mixture sit for 15 minutes, allowing the chemical reaction to dissolve grime.
  • Rinse with hot water to clear any remaining residue.


Best Used For:

  • Drains with foul odours.
  • Minor blockages caused by soap, grease, or food waste.
  • Regular maintenance to prevent buildup.


This method is an environmentally friendly alternative to harsh chemical drain cleaners. It is safe for most plumbing systems and can be used regularly to keep drains fresh and clear.

4. Use a Drain Snake or Auger

A drain snake or auger is useful for removing deep blockages caused by hair, food waste, or lodged debris. This tool is designed to physically remove obstructions rather than just dissolve them.

How to Use:

  • Insert the drain snake into the blocked drain.
  • Rotate or push it forward until resistance is felt.
  • Carefully pull back to extract the debris.
  • Run water to ensure the blockage has cleared.


Best Used For:

  • Shower and bathroom sinks clogged with hair.
  • Kitchen sinks with food blockages.
  • Toilets that do not respond to plunging.


Drain snakes are relatively inexpensive and can be a valuable addition to any home toolkit.

Preventative Measures to Avoid Future Blockages

To maintain clear drains and reduce the likelihood of future clogs, consider the following tips:

  • Regularly flush drains with hot water to dissolve grease buildup.
  • Use drain strainers to catch food scraps, hair, and debris.
  • Dispose of oil and grease properly instead of pouring them down the sink.
  • Avoid flushing non-biodegradable items like wipes and sanitary products.
  • Schedule routine drain maintenance with a professional plumber.

DB Pro Tip!

For persistent or recurring blockages, DIY methods may not be enough. Professional techniques such as hydro jet blasting and CCTV drain camera inspections can effectively remove stubborn clogs and identify underlying plumbing issues. When DIY efforts fail to restore proper drainage, seeking professional assistance is the best course of action. These professional plumbers ensure quality and safety in your home, regardless of which plumbing problems you have.

When to Call a Professional Plumber

Certain signs indicate the need for professional plumbing services, such as persistent drain clogs that do not respond to DIY solutions, slow drainage across multiple sinks or fixtures, foul odours emanating from the pipes, and unusual gurgling sounds when using sinks or toilets, all of which suggest underlying issues that require the expertise of a licensed plumber.

A 24-hour plumber can provide emergency assistance when blocked drains lead to overflowing sinks, sewer backups, or water damage. Ignoring serious blockages can result in costly repairs and potential health hazards.
