Introduction

Lismore Backflow Prevention

Backflow occurs when water flows in the wrong direction—potentially allowing contaminated water to enter your drinking supply. This can happen due to changes in water pressure, faulty valves or poor plumbing layouts.


At Origin Plumbing & Gas, we install and maintain backflow prevention devices throughout Lismore and beyond, to protect your water supply from contaminants like chemicals, sewage and sediment. Whether you're a homeowner near storm-prone zones or a business with cross-connections, we assess your risks and install devices that comply with local regulations. We also carry out annual testing and certification where required. If you're unsure whether your property is protected, we’re here to help. We also offer leak detection, septic system upgrades and stormwater drainage solutions.
