Backflow / RPZD Prevention

A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow. In water supply systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture. Water pressure may fail or be reduced when a water main bursts, pipes freeze, or there is unexpectedly high demand on the water system. Reduced pressure in the pipe may allow contaminated water from the soil, from storage, or from other sources to be drawn up into the system.

Testable backflow prevention devices at the property boundary must be installed on high or medium risk properties (Backflow risk can be classed as low, medium or high as per AS/NZS 3500.1:2015). These legally require testing at commissioning, after any maintenance and every 12 months by a licensed plumbing contractor qualified to test the devices.

Our plumbers at Marsmen Plumbing and Gas are skilled technicians who use specialised testing equipment to service all RPZ's (backflow prevention valves) and TMV's (thermostatic mixing valves).
