Grease and fat might seem harmless when they’re washed down the kitchen sink, but over time they can create serious problems inside your drainage system.
As grease and fat cool, they can stick to the inside of your pipes. Other food scraps, dirt and debris can then become trapped in the build-up, gradually restricting the flow of wastewater.
Eventually, this can lead to blocked drains, unpleasant smells, slow drainage and overflowing wastewater.
At Grantham Hydro, we help Auckland homeowners and businesses deal with a range of drainage problems, including stubborn blockages and build-up that can affect the performance of your pipes.
How Does Grease Get Into Your Drains?
Grease and fat commonly enter drainage systems through kitchen sinks and dishwashers.
Common sources include:
- Cooking oil
- Meat fat
- Butter
- Gravy
- Sauces
- Food scraps
- Greasy washing-up water
- Oil left in cooking pans
Even when grease initially goes down the sink as a liquid, it can cool further along the pipe and begin sticking to the internal walls.
Over time, these deposits can become thicker and restrict wastewater flow.
Can Grease and Fat Cause a Blocked Drain?
Yes. Grease and fat can be a major contributor to blocked drains.
The problem often develops gradually rather than happening overnight.
As grease accumulates inside a pipe, it creates a sticky surface where other materials can collect. Food particles, dirt, soap residue and other debris can attach to the grease, making the blockage increasingly difficult to clear.
Eventually, water may struggle to pass through the pipe properly.
If you’re experiencing recurring blockages, Grantham Hydro can help assess the drainage problem and determine an appropriate solution.
What Are the Signs of Grease Build-Up in Your Drains?
Grease-related drainage problems can develop slowly, so you may notice warning signs before the drain becomes completely blocked.
Look out for:
- Slow-draining kitchen sinks
- Gurgling sounds
- Unpleasant drain smells
- Water backing up
- Recurring kitchen sink blockages
- Greasy residue around the drain
- Drains that repeatedly need clearing
If you’ve noticed these signs, it’s worth dealing with the problem before it develops into a more serious blockage.
Why Does Grease Make Drain Cleaning Difficult?
Grease can be particularly troublesome because it doesn’t always create a simple blockage.
Instead, it can coat the inside of the pipe and gradually reduce the available space for wastewater to flow through.
This means your drain may still be working while already having a significant amount of grease build-up inside the pipe.
Repeatedly washing cooking fats and oils down the sink can eventually result in substantial deposits.
Can Hydro Jetting Remove Grease Build-Up?
Hydro jetting can be an effective way of removing stubborn build-up from drainage pipes.
The process uses high-pressure water to clean the inside of the pipe and remove accumulated grease, fat, sludge and other debris.
This can be particularly useful when traditional drain clearing isn’t enough or when grease build-up is contributing to recurring blockages.
Grantham Hydro provides professional hydro jetting services across Auckland, helping clear stubborn build-up and restore better flow through drainage pipes.
The appropriate method will depend on the condition of the pipe and the severity of the build-up.
Can Grease Cause Recurring Drain Problems?
Yes. If grease continues to enter your drainage system, the problem can return even after a blockage has been cleared.
For example, if a drain is unblocked but a thick layer of grease remains on the inside of the pipe, additional food debris and other material can become trapped, creating another blockage.
This is why recurring blockages may require more than simply clearing the immediate obstruction.
Grantham Hydro can assess recurring drainage issues and determine whether further cleaning, hydro jetting or a CCTV drain inspection may be appropriate.
What Should You Do With Cooking Fat and Oil?
One of the easiest ways to reduce grease-related drainage problems is to keep fats and oils out of your drains.
Instead of pouring cooking oil, fat or grease down the sink:
- Allow it to cool.
- Pour or scrape it into a suitable container.
- Dispose of it appropriately.
- Wipe greasy pans with paper towels before washing them.
This can help reduce the amount of grease entering your drainage system.
It’s also worth remembering that hot water and dishwashing liquid may help move grease through the pipe temporarily, but they don’t necessarily prevent grease from eventually cooling and sticking to the pipe further along.
What If Your Kitchen Drain Keeps Blocking?
If your kitchen drain repeatedly becomes blocked despite your best efforts, there may be significant build-up inside the pipe.
Grantham Hydro can assess the drainage problem and help determine what’s causing the recurring blockage.
Depending on the situation, solutions may include drain unblocking, hydro jetting or CCTV drain inspection.
Getting the underlying issue checked can help prevent you from repeatedly dealing with the same drainage problem.
How Can You Prevent Grease-Related Drain Problems?
Prevention is usually easier than dealing with a major blockage.
A few simple habits can help:
- Don’t pour cooking oil down the sink.
- Scrape food scraps into the rubbish or appropriate waste collection.
- Wipe greasy pans before washing them.
- Use sink strainers to catch food particles.
- Keep an eye out for slow drainage.
- Deal with recurring blockages early.
If your drains are already showing signs of a problem, professional cleaning may be more effective than relying on household remedies.

Frequently Asked Questions
Can pouring cooking oil down the sink block a drain?
Yes. Cooking oil and fat can cool inside drainage pipes and stick to the internal walls. Over time, this build-up can trap food debris and contribute to a blockage.
Does hot water remove grease from drains?
Hot water may help move some grease through the pipe temporarily, but it doesn’t necessarily remove accumulated grease from the internal walls. Persistent build-up may require professional drain cleaning or hydro jetting.
Can hydro jetting remove grease from drain pipes?
Yes. Hydro jetting uses high-pressure water to help remove grease, fat, sludge and other build-up from inside drainage pipes. Grantham Hydro provides hydro jetting services for stubborn drainage problems.
How much does it cost to unblock a drain in Auckland?
The cost depends on the location and severity of the blockage, the condition of the pipe and the equipment or service required. Grantham Hydro can assess your drainage issue and determine the appropriate solution.
How do I know if grease is causing my blocked drain?
Slow drainage, recurring kitchen sink blockages, unpleasant smells and water backing up can all indicate a drainage problem. A professional assessment can help determine whether grease build-up is contributing to the blockage.
