Stop Grease Build-Up Before It Damages Your Plumbing
Grease trap installation is essential for any commercial kitchen dealing with fats, oils, and food waste. When grease enters your wastewater system, it sticks to pipes and builds up over time. This can lead to blocked drains, strong odours, and costly plumbing repairs.
Many Central Coast businesses deal with the same issue again and again because the root cause has not been fixed.
At Silver Drains and Plumbing, we provide expert grease trap installation services across the Central Coast and Newcastle. Our licensed plumbers install systems that protect your drainage system and keep your business compliant.
If you’re dealing with grease build-up or ongoing drain issues, don’t wait for it to get worse. Call 0480 020 848 or book online today to get fast, reliable grease trap installation from a licensed plumber.
Why Grease Causes Ongoing Drainage Issues
Grease may look harmless when it goes down the sink, but once it cools, it hardens inside your pipes. Over time, this affects your entire wastewater system.
This is a common issue in commercial kitchens, restaurants, and food businesses where large amounts of grease are produced every day.
Signs Grease May Be Affecting Your Plumbing

If your sinks are draining slowly or you are dealing with repeated blockages, grease could already be affecting your pipes.
Bad smells, overflowing wastewater, or grease build-up around drains are also clear warning signs.
How Grease Trap Installation Solves the Problem

Installing a grease trap stops grease before it enters your pipes. A properly installed grease trap system separates grease from wastewater, protecting your plumbing and reducing the risk of blockages.
How a Grease Trap Works
Wastewater flows from sinks into the grease trap. Grease rises to the top while heavier waste settles at the bottom. Clean water then flows into your drainage system.
This simple process helps protect your pipes, sewer system, and the wider environment.
Why Grease Traps Are Required for Businesses
Most commercial plumbing systems require grease trap installation to meet plumbing codes and trade wastewater requirements.
Local councils and water authorities across the Central Coast and Newcastle require many businesses—especially restaurants, cafés and commercial kitchens—to install compliant grease trap systems.

Who Needs Grease Trap Installation
- Restaurants and cafes

- Food businesses
- Hospitality venues
Most commercial kitchens must install and maintain grease traps (grease arrestors) to comply with local trade wastewater requirements and remain connected to the sewer system.

Installing a grease trap is only part of the solution. If grease has already built up inside your pipes, it can continue to cause problems even after a new system is installed.
Before installation, we can clear your pipes using high-pressure jet blasting to remove grease, sludge, and debris. This ensures your drainage system is clean and ready, so your new grease trap works properly from day one.
If needed, our team can also carry out CCTV drain inspections to check the condition of your pipes and identify any hidden problems. This allows us to provide a complete solution, not just a quick fix.
