Drain blockages are one of the most common — and most preventable — plumbing problems on the Gold Coast. Most blockages build up gradually from what goes down the drain, so a few simple habits can keep your drains flowing and reduce the chance of an expensive emergency.
What not to put down your drains
The single most effective way to prevent blocked drains is to be careful about what enters them in the first place:
- Cooking grease and oil — liquid when warm, but solidifies in the pipe and builds up on the walls. Wipe greasy pans with paper towel before washing.
- Coffee grounds — don't dissolve and settle in pipes. Bin them instead.
- Rice and pasta — expand in water and can form a sticky mass. Scrape plates into the bin first.
- Eggshells — the membrane can catch on pipe imperfections and the shells don't break down.
- "Flushable" wipes — most don't break down and are a leading cause of toilet and sewer blockages. See our article on whether flushable wipes are really flushable.
- Sanitary products, cotton buds and dental floss — bin these, never flush them.
Use sink strainers
A simple sink strainer catches food scraps before they enter the drain. Empty it into the bin or compost rather than rinsing it through. Strainers are inexpensive and prevent the most common cause of kitchen drain blockages.
Run hot water regularly
After washing up, run the hot tap for 30 seconds to flush any residual fat through the system before it can solidify. This is a simple habit that helps prevent grease buildup in kitchen drains.
Don't ignore slow drains
A slow drain is an early warning of a developing blockage. Tree roots, grease buildup and partial collapses all start as slow drainage. Having a slow drain investigated with a CCTV camera before it blocks completely is far cheaper than an emergency callout — see our blocked drains service.
Be careful with chemical cleaners
Caustic and acidic drain cleaners can sometimes clear a soft blockage, but they're a blunt instrument. They can corrode older pipes, damage rubber seals, and make it hazardous for a plumber who later opens the pipe. A plunger or a drain snake is a safer first step. If the blockage persists, professional clearing is more effective.
Maintain your gutters and downpipes
Stormwater drains block with leaves and debris washed in from gutters. Clear gutters and downpipes before the storm season to prevent stormwater overflow. See our guide on clearing downpipes and gutters
Consider periodic CCTV inspection
For older Gold Coast homes with earthenware or clay drains, a periodic CCTV inspection can identify tree root intrusion, sagging sections or partial collapses before they cause a blockage. This is particularly valuable if you've had recurring blockages — a camera inspection finds the cause rather than just clearing the symptom.
When to call a plumber
If a drain is repeatedly slow, multiple drains are affected at once, or there's any sign of overflow, it's time for professional help. Our team uses CCTV cameras to diagnose the cause and high-pressure water jetters to clear blockages properly. Contact our Gold Coast team to arrange a drain inspection.
