Backflow & Compliance Testing

Under the Water Services Act 2012 and Water Services Regulations 2013, every property in Western Australia with a fire service connection to Water Corporation must have an approved backflow prevention containment device at the boundary. These devices stop potentially contaminated water from flowing back into the public supply.

Testable backflow devices must be tested annually by an accredited tester, with reports submitted to Water Corporation within 5 working days. Non-compliance carries penalties of up to $5,000 plus $500 per day — and Water Corporation can disconnect your service.

Our accredited testers handle the full process — testing to AS/NZS 2845.3, lodging reports directly with Water Corporation, and scheduling your next test so nothing lapses.

DFES relies on hydrant systems more than any other equipment when fighting fires. Fire brigade booster inlets provide the connection point for DFES to pump additional water into your building's hydrant system during firefighting operations.

The 5-yearly booster inlet flow test under AS 1851 proves that DFES can successfully supplement your internal hydrant system. It verifies there are no obstructions, corrosion or blockages in the reticulation pipework between the booster and the most hydraulically remote hydrant.

We carry out this specialist testing with our own pumping equipment and trained crew. Our technicians have genuine operational fire training experience, so they understand exactly what these systems need to deliver when it counts.

RCDs are life-safety devices designed to cut power in a fraction of a second during an electrical fault. Testing confirms they trip within the required timeframes set out in AS/NZS 3760. Tests include trip time testing, ramp testing and a visual inspection of each unit.

When an RCD fails to trip in the required time, the consequences can be fatal. Regular testing ensures your devices will respond correctly when a fault occurs — protecting your people and meeting your WHS obligations.

Our qualified electrical team tests RCDs alongside your fire equipment inspections, so everything stays on one schedule with one provider. Results are documented and available through your client portal.
