Grease trap cleaning and maintenance
Grease traps quietly sit behind the scenes in cafés, restaurants, takeaways, bakeries and commercial kitchens. You don’t see them, but they’re doing a big job: keeping fats, oils, food scraps and wastewater out of sewer lines while protecting your plumbing and preventing costly blockages.
Here’s how they work, why regular cleaning matters, and why hundreds of Riverina and ACT businesses trust Smallmon’s to handle theirs.
What's a Grease Trap?
A grease trap is a tank in your plumbing that catches fats, oils, food scraps and muck before it hits the sewer.
Its job is simple :
- Capture solids (like food scraps, lint and debris)
- Hold back fats, oils and grease
- Allow clean water to flow out to the sewer system
When it’s looked after properly, it protects your pipes, your wallet and council infrastructure. When it’s not looked after, you know about it pretty quickly!
How It Works
When your sinks drain, wastewater enters the trap, where:
Solids sink to the bottom
Grease and oil rise to the top
Cleaner water exits through the outlet pipe
A freshly serviced trap is 99% water and 1% solids. As your business operates day after day, solids accumulate. Once that sludge reaches the top, the trap stops doing its job. If left too long, waste can bypass the trap entirely, ending up in the sewer or backing up into your building.
You’ll know when this happens because the whole kitchen will smell like trouble.
Why It Needs Regular Cleaning
Grease traps fill up whether you notice or not. Leave it too long and you’ll be dealing with:
Stinks in the kitchen (you can usually smell it before you see it)
Slow drains and backups
Overflows – weekends love to ruin themselves this way
Breaches of your trade waste agreement
Avoidable repair bills
Most councils set mandatory pump-out schedules, typically every 1–3 months, depending on the size of your kitchen and the trap.
Skipping a service doesn’t save money. In fact, it usually costs you a whole lot more later.
