Blocked Drains Auckland

Drain Unblocking Services

Auckland's clay soil and older pipe networks mean blocked drains are one of the most common plumbing problems we deal with. From kitchen sinks to main sewer lines, Water & Gas Worx has the tools and experience to clear the lot.

Signs You Have a Blocked Drain

• Water draining slowly from sinks, showers, or baths
• Gurgling noises from drains or toilets
• Bad smells coming from drains or gully traps
• Water backing up in the shower when you flush the toilet
• Overflowing gully traps or inspection chambers
• Wet patches or pooling water in the yard

If you're seeing any of these, don't wait — blocked drains get worse quickly and can cause water damage or sewage overflow. Call us and we'll sort it.

Common Causes of Blocked Drains in Auckland

Auckland's mix of older clay pipes and modern PVC systems means drain blockages come from a range of causes. Here are the most common ones we deal with:

• Tree root intrusion — roots seek out moisture and grow into pipe joints, especially in older clay sewer lines. This is the number one cause of blocked drains in Auckland's established suburbs.
• Grease and fat build-up — cooking fats solidify inside kitchen drain pipes over time, gradually narrowing the pipe until water can no longer pass through.
• Hair and soap accumulation — bathroom drains collect hair, soap scum, and product residue that forms a thick plug in the trap or pipe.
• Foreign objects — wet wipes, sanitary products, nappies, and children's toys flushed down the toilet are a guaranteed blockage waiting to happen.
• Broken or collapsed pipes — ground movement, age, or heavy vehicle traffic above buried pipes can crack or collapse a section, causing repeated blockages in the same spot.
• Stormwater debris — leaves, dirt, and sediment wash into stormwater drains and gully traps, especially during Auckland's heavy autumn and winter rain.

If your drains keep blocking in the same spot, it usually points to a structural issue like root intrusion or a collapsed pipe. A CCTV drain inspection will show exactly what is going on so we can fix the cause, not just clear the symptom.
