How to Unblock and Clean Bathroom Drains Sutherland Shire

June 12, 20250

Blocked bathroom drains are one of the most common plumbing issues faced by households across Sutherland Shire. Whether it’s a slow-draining shower, a clogged vanity sink, or water pooling around the floor waste, ignoring the problem can lead to bad smells, pipe damage, and even flooding. Fortunately, many bathroom drain clogs can be cleared at home with simple tools and methods. In this guide, SE Plumbing explains how to unblock and clean bathroom drains the right way and when it’s time to call a professional plumber in Sutherland Shire.

What Causes Bathroom Drains to Block?

Bathroom drains deal with more than just water. Hair, soap scum, toothpaste, and even cleaning products can build up over time and create stubborn clogs. The most common causes include:

  • Hair and body products accumulating in shower and basin pipes
  • Soap and shampoo residue solidifying in bends and joints
  • Toothpaste and debris from vanity sinks
  • Cotton buds or dental floss flushed down the wrong drain
  • Poor drainage slope or pipe alignment in older homes

Step-by-Step: How to Unblock and Clean a Bathroom Drain

1. Remove the Drain Cover and Clear Surface Debris

Start by taking off the shower grate or basin plug to remove any visible hair or soap scum.

  • Use gloves or a paper towel to remove debris
  • Rinse the area with hot water

This simple step can often restore flow, especially for slow shower drains.

2. Use Boiling Water

Boiling water helps loosen soap buildup and flush away light debris.

  • Boil a full kettle and pour it slowly down the drain
  • Wait five minutes, then test the flow with cold water

Avoid using boiling water on plastic pipes, and don’t use this method in toilet bowls.

3. Apply a Bicarb Soda and Vinegar Flush

This natural cleaning method is safe and effective for bathroom pipes.

  • Pour half a cup of bicarbonate soda into the drain
  • Follow with one cup of vinegar
  • Cover the drain and leave it to fizz for 15 minutes
  • Rinse with hot water

This solution works well for odours too. Learn more in our blog on DIY tips for blocked drains.

4. Use a Drain Snake or Wire Hook

If the clog is deeper down, you may need to physically remove it.

  • Use a store-bought drain snake or make a hook with a wire coat hanger
  • Insert it carefully into the pipe and twist
  • Pull out hair and debris, then flush the drain

If you’re unable to remove the blockage manually, call SE Plumbing for Emergency Plumbing help.

5. Try a Plunger

For stubborn clogs in basins or shower drains, a plunger can help.

  • Fill the basin with water to cover the plunger
  • Create a seal and plunge up and down firmly
  • Check if water drains freely afterward

Repeat the process if needed, but avoid aggressive plunging on older or brittle plumbing systems.

How to Prevent Bathroom Drain Clogs

Preventing blockages is easier than fixing them. Regular maintenance can keep your bathroom plumbing healthy year-round.

  • Install hair catchers in showers and basins
  • Avoid washing long hair or shaving directly over open drains
  • Flush your bathroom drains monthly with hot water and baking soda
  • Avoid flushing cotton products or wipes

SE Plumbing also provides Leaking Taps and Toilets service to address hidden bathroom plumbing issues before they become major problems.
