Product Overview

Summary: This Plumbing Connections Safe Operating Procedure sets out a clear, step‑by‑step method for installing, modifying and testing plumbing connections safely and compliantly. It helps Australian businesses control water, gas and wastewater risks, prevent leaks and contamination, and protect workers, occupants and property from preventable incidents.

Plumbing connections are critical to the safe and reliable operation of any building or site, yet they are also a frequent source of leaks, water damage, cross‑contamination and gas incidents when not managed correctly. This Plumbing Connections Safe Operating Procedure provides a structured, practical framework for how plumbing work is planned, carried out, checked and documented on Australian sites. It focuses on both safety and compliance, integrating WHS obligations with relevant plumbing and building standards so your team follows a consistent, defensible process every time.

The SOP covers a wide range of connection types typically encountered in commercial, residential and industrial environments, including potable water, hot water, recycled water, sewer, stormwater and, where applicable, gas connections. It sets out pre‑start checks, isolation and lock‑out requirements, verification of existing services, correct use of tools and materials, pressure and leak testing, and site reinstatement. By implementing this procedure, businesses reduce the risk of water ingress and structural damage, minimise exposure to contaminated water and sewage, and prevent gas leaks or uncontrolled releases. It also supports better coordination between plumbers, other trades and site management, reducing rework, call‑backs and disputes while demonstrating due diligence under Australian WHS and plumbing legislation.
