How do I know if my grease trap is blocked?
Leaving a blockage alone risks water contamination and pest infestation. Here's how to identify one early:
Slow drainage
Sinks draining slowly could indicate a grease build-up inside the trap.
Unpleasant odours
Bad smells similar to rotten eggs coming from your drains are a classic warning sign.
Water backup
Water frequently backing up in the sinks or onto floors points to a blocked trap.
Visible grease
Grease around drains or the trap suggests it's no longer separating grease from wastewater effectively.
Detected one or more of these signs? Reach out immediately so your commercial kitchen stays safeguarded and compliant.
The role grease traps play in your business
Otherwise known as grease collectors, these systems prevent fats, oils and grease (FOG) from entering sewer lines — because once FOG infiltrates, it causes major blockages and harms the local environment.
The food service industry generates a build-up of grease over time, so when the trap is inefficient, backups and overflows follow.
Our team services trade waste systems in line with the Plumbing Code of Australia and local water authority requirements — a reliable choice for handling any blockage, no matter the extent.
How we unblock grease traps
The repair varies with the level of damage — our licensed plumbers work across stainless steel, fibreglass and concrete traps, always returning them to working order.
- 1
Cleaning a grease trap
High-pressure jet blasting at up to 5500 PSI — heated for stubborn blockages — blasts away any build-up, restoring the collector's hygiene.
- 2
Grease trap repair
For minor damage we adjust faulty pipes and connections, and smoothly replace leaky components like seals, gaskets and baffles.
- 3
Grease trap replacement
When damage is severe, we seek the required water authority approval, then expertly disconnect, remove and connect a brand new compliant system.

Grease trap blockages cause major disruptions to business operations — the right preventative measures keep things running:
Meet water authority guidelines

Grease trap FAQs
What Melbourne cafe and restaurant owners ask us about grease traps.
How should I respond if a grease trap overflows?
Stop using any kitchen equipment that drains into it immediately, and clean up spills quickly to avoid safety hazards. Then contact a licensed waste transporter to properly pump out and clean the trap.
How can a grease trap get clogged?
Beyond grease itself, food waste, debris and collected oils slip into commercial kitchen drains. Over time this build-up hardens, causing a blockage in the trap.
What is the life expectancy of a grease trap?
It varies with how often it's used, but on average a grease trap lasts five to seven years with the right maintenance.
What happens if I don't maintain my grease trap?
Failing to maintain your grease trap to your water authority's guidelines risks monetary penalties — and compromises the wellbeing of your staff and customers.
