A blocked kitchen drain always seems to happen at the worst time. One minute everything’s sweet, the next your sink’s filling up, smelling a bit rough, and refusing to drain properly.
Across Auckland, many blocked drains are caused by everyday habits most people don’t think twice about. The good news? A few simple changes can help prevent expensive plumbing problems down the track.
At Grantham Hydro, we help homeowners across Auckland quickly and properly sort blocked drains using advanced drain-cleaning equipment, hydro-jetting, and CCTV inspections.
Here are some of the most common kitchen habits that can clog your drains.
Pouring Grease and Oil Down the Sink
After cooking dinner, it’s easy to rinse leftover oil or fat straight down the sink. But once grease cools, it sticks to the inside of your pipes and slowly builds up over time.
Before long, food scraps and debris start getting trapped, leading to stubborn blockages.
Better way to handle grease:
- Let the cooking oil cool first
- Pour it into a container and throw it in the rubbish
- Wipe greasy pans with a paper towel before washing
If your pipes are already clogged with grease, professional drain unblocking services can clear the blockage safely and properly.
Washing Food Scraps Into the Drain
A few bits of rice or pasta might not seem like a big deal, but over time, food scraps can create major blockages.
Some of the worst offenders include:
- Rice
- Pasta
- Coffee grounds
- Eggshells
- Vegetable peelings
- Fatty leftovers
These materials often stick inside pipes, especially when mixed with grease.
Easy prevention tips:
- Scrape plates into the bin before rinsing
- Use a sink strainer
- Compost food scraps when possible
Flushing Wipes and Paper Towels
Despite what the packaging says, many “flushable” wipes don’t break down properly in pipes. Paper towels and wipes can quickly create serious drain blockages, especially in older Auckland homes or properties with septic systems.
The safest option is simple:
- Only flush toilet paper
- Put wipes and paper towels in the rubbish bin
Ignoring Slow Drains
A slow-draining sink is usually an early warning sign that something’s building up in your pipes.
Many people leave it too long, only calling for help once the sink is completely blocked or starts overflowing.
Signs your kitchen drain may be blocked:
- Water draining slowly
- Gurgling noises
- Bad smells from the sink
- Water is pooling around the drain
Getting the issue sorted early can save you a lot of hassle and money later on.
Using Harsh Chemical Drain Cleaners
Supermarket drain cleaners might seem like a quick fix, but they often only partially clear blockages and can damage pipes over time.
For recurring or stubborn blockages, professional cleaning is usually the better option.
Hydro jetting services use high-pressure water to clear grease, debris, and even tree roots from drains without harming your plumbing system.
Skipping Regular Drain Maintenance
Most people don’t think about their drains until there’s a problem. But regular maintenance can help prevent major plumbing emergencies before they happen.
Routine inspections and cleaning can:
- Remove buildup before it blocks pipes
- Detect cracked or damaged drains early
- Improve drainage performance
- Prevent costly repairs
At Grantham Hydro, we provide preventative drain maintenance services across Auckland to help keep your plumbing system running smoothly year-round.

Frequently Asked Questions
What causes blocked kitchen drains?

Can I use boiling water to unblock a drain?
Boiling water may help with minor grease buildup, but it usually won’t completely clear serious blockages.
