Ensuring Compliance and Efficiency

Our team at Duncan’s Plumbing Heating and Air Conditioning understands the critical role compliance plays in the seamless operation of your business. We specialise in making sure your trade waste and grease trap systems meet all regulatory standards.

Here’s how we tailor our services to different industries:

  • Auto Trades Businesses:
    From mechanics and panel beaters to car wash operators, we ensure compliance for all auto trades businesses. Most in this category will need in-sink and in-floor bucket traps, along with an oil water separation system featuring a collection pit and pump.
  • Diverse Range of Systems:
    Our expertise extends to a variety of systems, including above and below-ground options, pumped trade waste solutions, modular systems, concrete grease traps, and poly grease traps. We tailor our solutions to your business’s specific requirements, ensuring optimal performance.
