What is a Grease Trap Installation?
A grease trap installation is a specialised plumbing process designed to intercept Fats, Oils, and Grease (FOG) before they enter the public sewer system. When hot grease is poured down a drain, it cools and solidifies, leading to massive blockages known as “fatbergs.” In Sydney, commercial food businesses are required by law to install an approved grease arrestor to mitigate this risk.
A Plumbnet installation involves more than just a tank. It requires a deep understanding of hydraulic flow, proper venting to eliminate foul odours, and the installation of Backflow Prevention devices to protect the mains water supply. As Conserve-certified professionals, we ensure that every component from the gastight sealed lids to the internal baffles, meets AS/NZS 3500 standards and local LGA requirements.

Our End-to-End Trade Waste Services in Sydney
Every kitchen has a different footprint. We provide brand-specific and size-specific installations tailored to your site’s constraints.
Above-Ground Polyethylene Grease Traps
Ideal for kitchens with limited space or those located on upper levels of shopping centres. We install compact, high-durability units from brands like Halgan or Viking, which are lightweight yet incredibly robust.
Below-Ground Concrete & Fiberglass Arrestors
For large-scale restaurants and industrial kitchens, we manage the excavation and installation of heavy-duty below-ground traps. These systems are designed for high-volume filtration and are built to withstand traffic loads if installed in car parks or loading docks.
Trade Waste Venting & Drainage
Incorrect venting is the #1 cause of kitchen odours. We design and install high-level vents that ensure air pressure is balanced and smells are dissipated away from customer areas and neighbouring properties.
Backflow Prevention & Sampling Points
Sydney Water requires specific sampling points to be installed so they can test the quality of your discharge. We install these access points and provide certified Backflow Prevention testing to ensure no waste ever siphons back into your clean water lines.
Grease Trap Pump-Out Coordination & Maintenance
We coordinate scheduled grease trap pump-outs, internal cleaning, and waste disposal management to prevent overflow risks, drainage blockages, and non-compliance penalties from Sydney Water inspections.
Commercial Kitchen Drain Upgrades
Our plumbers upgrade undersized kitchen drainage systems with correctly graded pipework, heavy-duty floor wastes, and high-flow trade waste connections for improved discharge performance.
The Plumbnet Installation Process
Pipework & Connection
We integrate the grease trap into your existing drainage system using high-temperature-resistant PVC or HDPE piping.
Lid & Riser Fitting
We install gas-tight lids (available in various load ratings, including Class B and D for driveways) to ensure the unit is flush with your floor surface.
Final Commissioning & Certification
We complete all Sydney Water compliance paperwork and provide you with the final certification required for your business license.
Trade Waste Assessment
We review your "Kitchen Schedule" to determine the correct Litre capacity (e.g., 1000L, 2000L, or 5000L) required for your specific equipment.
Site Preparation & Excavation
For below-ground units, we manage the precision trenching and base preparation, ensuring the unit is level and structurally supported.

Frequently Asked Questions
How do I know what size grease trap I need?
The size is determined by the number of sinks, dishwashers, and floor wastes in your kitchen. Sydney Water uses a specific formula to calculate this. We can assist in evaluating your plans to ensure you don’t overspend on a unit that is too large or fail inspection with one that is too small.
