A blocked drain is one of the most common plumbing issues in New Zealand homes. Whether it’s your kitchen sink, shower, or toilet, blockages can cause slow drainage, bad smells, or even overflows if left untreated. While some situations definitely need a plumber, there are a few things you can try first.
Start by identifying which drain is blocked. If it’s just one fixture, like your bathroom basin or kitchen sink, the issue is likely local. But if multiple drains are backing up at once, it could be a deeper issue in your main line or gully trap — and that’s when you’ll want a professional to take a look.
For minor sink or shower blockages, boiling water is a good first step. Pour it slowly down the drain to help loosen grease or soap buildup. You can also try a baking soda and vinegar mix, which fizzes and helps break down organic matter. Wait 15 minutes, then flush with hot water again.
Plunger use is another effective option. Make sure there’s enough water in the basin or bowl to cover the plunger head, then plunge firmly to create pressure. If the blockage is close to the surface, this can often clear it in a few goes.
Avoid using chemical drain cleaners. While they might offer a quick fix, they can damage your pipes over time — especially in older homes with copper or PVC systems. If you find yourself using chemicals regularly, the real issue probably needs a plumber’s attention.
Hair, food scraps, grease, and wipes are the most common causes of blocked drains. Installing simple drain covers in your sinks and showers can help prevent future issues. Never pour oil or coffee grounds down the sink — even if they seem to wash away, they build up and cause blockages over time.
If your drain is still blocked after trying these steps, or if water is backing up quickly, it’s time to call a licensed plumber. At Flowstate, we use proper tools like drain snakes and CCTV cameras to locate and clear the blockage safely — no guesswork, no mess.
