Open grease trap in a commercial kitchen with built-up fat and grease

Plumbers for Commercial Kitchens That Can’t Afford Downtime

A grease trap (or grease arrestor) is the tank that intercepts fats, oils and grease from a commercial kitchen’s wastewater before it reaches the sewer. In Sydney, food businesses, cafés, restaurants, pubs, clubs and food halls, are required under Sydney Water’s trade waste rules to have a correctly sized grease trap and to keep it maintained.

When a trap is undersized, damaged or neglected, grease hardens, the kitchen backs up, and the business risks fines and downtime.

We’re not just general plumbers. We’re commercial specialists who understand the daily pressure of commercial food operations. From small takeaway shops to large restaurant chains, we provide expert, commercial-grade plumbing backed by experience, transparency, and urgency.

Do I Legally Need One?

Sydney Water regulates trade waste, which includes the fats, oils and grease produced by commercial food preparation.

Most food businesses need a grease arrestor sized to their kitchen’s output and connected under an approved trade waste agreement. We design and install systems that meet those requirements and help with the council and Sydney Water documentation, so you pass inspection without delays to your opening or fit-out.

Grease Traps need To Be Fully Compliant

Sydney councils and Sydney Water have strict requirements for grease trap sizing, positioning, and installation standards. We understand the codes and build systems that not only meet regulations but are tailored to your commercial kitchen’s daily output.

Whether you’re launching a new food venue or upgrading an aging trap, our plumbers design systems to suit your kitchen’s grease volume, pipe flow, and drain configuration. We deliver the best installations, repairs, and plumbing maintenance for all business owners.

Our Grease Trap Services Include:

Grease Trap Installations

New grease trap installation for cafés, restaurants, food halls, pubs, and clubs
Design consultations to select the right grease trap size and configuration
Integration with existing commercial plumbing and trade waste systems
Fast-track council compliance, including documentation support
Upgrades and retrofits to bring old systems up to code

Every install is completed by a licensed plumber with commercial experience, no subcontractors, no guesswork, and no delays.

Grease Trap Blockage and Repairs – Fast Response Times

Grease traps are designed to intercept fats, oils, and grease (FOG), but over time, these materials harden and cause internal clogs or component failures. When this happens, you need more than a cleaner, you need a plumber with the tools and experience to remove grease blockages, replace failed parts, and restore system flow.

Common Repairs and Maintenance Services:

Clearing grease trap blockages in inlets, outlets, and internal chambers
Replacing cracked or corroded tank walls, lids, or internal baffles
Repairing leaks around pipe entry points or access covers
Fixing connection issues between grease traps and trade waste lines
Recommissioning traps after long periods of disuse

We’re available across Sydney to clear blocked grease traps, replace broken baffles, and repair damaged connections. Our team uses commercial-grade tools to get your system running again, fast.

We do not perform routine grease trap pump-outs or cleaning services — but we work closely with cleaners and facility managers to provide complementary plumbing support when deeper blockages or mechanical failures arise.

 Trustindex verifies that the original source of the review is Google. We had a blocked sewer and Craig from The Blocked Drain Guys came out straight away. He was fair, honest, kind, and cleared the problem quickly. Highly recommend them for fast and efficient service – thank you Craig!

For context, before calling Craig we had contacted another company (Dans Plumbing). While they partially cleared the blockage, they then tried to pressure us into unnecessary “repairs” with a ridiculous $17,000 quote, making false claims about damaged pipes. We refused, but still had to pay $1,250 for their overpriced call-out.

In the end, Craig solved the issue properly without the nonsense. If you want genuine service without being ripped off, go with The Blocked Drain Guys.

 Trustindex verifies that the original source of the review is Google. Craig was fantastic to deal with from start to finish. He was incredibly patient, took the time to explain everything clearly (and I had a lot of questions!), and made sure I fully understood what was going on. His work was super thorough, and he managed to clear my blocked drain on the same day—which was such a relief!

On top of that, his pricing was very reasonable, especially for the quality of service provided. I’m so grateful and will definitely be using Craig as my go-to plumber from now on. Highly recommend to anyone looking for a plumber they can trust!

FAQS For Grease Traps

Find answers to common questions about grease traps

Does my café or restaurant legally need a grease trap in Sydney?

In almost all cases yes. Sydney Water’s trade waste rules require food businesses to have an appropriately sized grease arrestor connected under a trade waste agreement.

What size grease trap do I need?

It depends on your kitchen’s output and fixtures. We size the trap to your venue’s grease volume and drain layout so it meets requirements and won’t clog prematurely.

What are the signs of a blocked grease trap?

Slow-draining kitchen sinks, foul odours, gurgling drains, backups during service, or overflow around the trap. These mean the trap needs clearing before it stops the kitchen.

Do you pump out or clean grease traps?

We don’t do routine pump-outs. We install, repair and clear blockages, and work alongside your trap cleaners when a deeper blockage or mechanical failure needs a plumber.

How often should a grease trap be serviced?

Cleaning frequency is set by Sydney Water based on your trap and output (often every few weeks). On top of cleaning, have a plumber check for damaged baffles, leaks and failing connections.
