Commercial Plumbing Maintenance in Hornsby & Northern Sydney

O'Brien Plumbing Hornsby provides expert commercial plumbing maintenance for facilities, strata managers, healthcare providers, and retail businesses across the Upper North Shore and Hills District. We understand that commercial plumbing systems require a higher level of compliance, reliability, and rapid response than standard residential plumbing. A failure in a commercial setting can result in severe operational downtime, health risks, and regulatory fines.

As a CM3 accredited contractor, we deliver structured preventative maintenance programs and 24/7 emergency support to keep your business compliant and operational. We are the trusted compliance partner for major national operators, including Bupa Aged Care, delivering rigorous testing and maintenance across their facilities for nearly a decade.

Our Commercial Plumbing Services

We offer a comprehensive suite of commercial plumbing services tailored to the specific needs of Hornsby businesses and facility managers:

  • Preventative Maintenance Contracts: Custom scheduled maintenance plans designed to identify and resolve potential issues before they cause costly downtime. We manage asset registers and compliance schedules so you don’t have to.
  • TMV Testing & Compliance: Annual Thermostatic Mixing Valve testing and certification for healthcare, aged care, and early learning centres.
  • Backflow Prevention Testing: Annual testing, certification, and reporting to Sydney Water for all commercial backflow devices.
  • CCTV Drain Inspections & Hydro-Jetting: Advanced diagnostics and high-pressure clearing for complex commercial blockages and recurring drainage issues.
  • Commercial Kitchens & Retail: Grease trap installation and servicing, commercial gas fitting, and tenancy plumbing fit-outs.
  • Strata & Property Management: 24/7 emergency plumbing response for common-area plumbing issues, with clear tenant liaison protocols and detailed reporting for strata committees.
