8 Common Causes of Blocked Drains in Gold Coast Homes (and How to Prevent Them)

What you need to know about blocked drains in Gold Coast homes

Drainage systems play an essential role in moving wastewater and rainwater away from your property to prevent water damage and health issues. 

Understanding stormwater management can also help you avoid problems before they start, as stormwater can carry debris into your outdoor drains if not managed properly.

Let’s explore the eight most common drain blockage causes in Gold Coast homes and how to prevent them.

1. Why is hair clogging your bathroom drains?

Hair is a top culprit for bathroom blockages because it easily tangles and forms clumps in your pipework. When soap residue joins in, the buildup can make water drain very slowly or stop entirely.

Simple ways to avoid hair buildup:

  • Place a hair catcher or strainer over shower and basin drains.
  • Clear collected hair regularly so it doesn’t enter the pipe.
  • Brush long hair before washing where possible.

2. What happens when grease and food go down your kitchen sink

Kitchen sink blockages often begin with grease and food scraps. Fat and oil cool and solidify, which traps other debris and creates tough clogs deep inside the pipes.

Helpful habits for your kitchen:

  • Bag and bin cooking oil instead of pouring it down the sink.
  • Scrape plates into the bin before rinsing dishes.
  • Run hot water after washing greasy pots.

3. Why flushing the wrong things can block your toilet

Toilets are designed for human waste and toilet paper only. Flushing wipes, cotton buds, feminine hygiene products, or other items can lead to instant blockages that affect more than just one drain.

Better disposal habits for toilets:

  • Keep a small bin in the bathroom for all other waste.
  • Remind children what is safe to flush.
  • Avoid items labelled “flushable” if they don’t break down easily.

4. How tree roots can invade your underground pipes

Tree roots naturally seek moisture, and small cracks in underground pipes are an easy water source. Once inside, roots grow and expand, blocking flow or even damaging the pipe.

Ways to manage root intrusion:

  • Get regular drain inspections by a plumber like EVR Plumbing.
  • Avoid planting trees near sewer lines.
  • Consider root barriers if trees are close to underground pipes.

5. Is soap scum building up in your drains?

Soap scum doesn’t dissolve completely. Over time it sticks to pipe walls and combines with other debris to create sticky barriers that slow drainage.

Easy steps to reduce soap scum:

  • Choose soaps with fewer additives that leave less residue.
  • Flush drains with hot water weekly.
  • Have drain cleaning done periodically.

6. Could poor installation be causing your drainage issues?

Sometimes the pipework itself is the cause. Incorrect installation, misaligned joints, or improper pipe slope can stop debris from flowing properly, meaning even normal use can lead to blockages.

What to consider here:

  • Always work with licensed professionals for plumbing work. Australian plumbing standards like those described by the Plumbing Code of Australia show how pipes should be correctly installed.
  • If you’re buying a home, get a plumbing inspection first.

7. What heavy rain can do to your stormwater drains

Gold Coast weather can change quickly. During heavy rain, stormwater drains can become overwhelmed if gutters and outdoor drains aren’t maintained. Organic material and debris can wash into pipes, slowing flow and eventually causing backups.

Storm-ready tips:

  • Keep gutters and outdoor drains clear of leaves and debris.
  • Install correct stormwater drainage near your home.
  • Use grated covers to catch large debris.

8. Are ageing pipes causing hidden drain problems?

Older pipes are more prone to corrosion, cracks, or mineral buildup. These issues make pipes narrower and more likely to trap debris over time.

Signs of ageing pipes to watch for:

  • Repeated blockages in the same place.
  • Slow drainage in multiple fixtures.
  • Discolouration or odd tastes in water.

Professional inspection can help you identify these issues early.

Easy ways to prevent blocked drains in your Gold Coast home

Keeping your drains flowing doesn’t have to be difficult. Here are some practical steps you can take:

  • Use drain strainers in all sinks and showers.
  • Avoid pouring fats or oils down the drain.
  • Flush bathroom drains with hot water weekly.
  • Teach your household what can and can’t go down the drain.
  • Book a professional drain inspection annually with your local, trusted plumbing professionals.

Being proactive will help keep your plumbing system functioning smoothly.
