Our licensed plumbers can test existing prevention devices, explain the results and arrange repairs or maintenance where required. You will receive clear upfront pricing before work begins, with service available throughout Perth and surrounding suburbs. Any applicable test details and documentation are completed after the test so you have an accurate record of the device’s condition and performance.
Water within a plumbing system should normally travel in one direction. Changes in pressure can sometimes cause it to move backwards through a connection, potentially drawing water from a property back towards the potable supply. A backflow prevention device creates a barrier between drinking water and plumbing systems, equipment or substances that may present a contamination risk.
Internal parts can wear, seize, leak or stop sealing correctly over time. The outside of a device may appear to be in reasonable condition while its valves or relief components fail during a performance test. Backflow prevention testing identifies these faults before the device can no longer offer its intended level of protection.
Registered property-boundary devices generally require testing when they are commissioned, every year after that and following maintenance. Property owners and managers should also respond to Water Corporation notices and keep track of any established testing schedule. Testing can:
Impressive Plumbing and Gasfitting can assist throughout the working life of a backflow prevention system. Our plumbers can assess an existing device, carry out testing and maintenance, and recommend replacement where the installed unit is damaged, outdated or no longer suitable.
During annual backflow testing, the plumber uses appropriate equipment and testing procedures to check the performance of a testable prevention device. This includes assessing how its internal valves and other components respond under controlled pressure conditions.
Annual testing may be required for registered boundary devices and for devices installed at certain commercial, industrial or higher-risk properties. The test result is recorded, and any applicable documentation is completed so the property owner or manager has an accurate service record.
An inspection looks at the device’s general condition, accessibility and surrounding installation. The plumber may check for visible corrosion or leakage, assess valve operation, inspect test points and identify any installation or access concerns that could affect testing or maintenance.
A visual inspection is not a substitute for a required performance test. It can, however, identify obvious damage, deterioration, obstructions or maintenance issues that should be addressed before the device is tested or serviced.
If a device fails testing or shows signs of a fault, the plumber will assess the likely cause and discuss the available options. Depending on the condition of the unit, work may involve cleaning internal components, replacing seals, springs or valves, repairing leaks or replacing damaged parts.
The plumber will explain the fault and provide pricing before additional work begins. Some devices may need replacement rather than repair, depending on their age, condition and suitability. A repaired device may also need to be retested before it can be recorded as passing.
New installations and replacements must suit the property, plumbing connection and identified risk. The correct approach to backflow prevention Perth properties require depends on the assessed hazard level, the intended use of the water and the type of potential contamination source.
The plumber will also consider relevant Water Corporation and plumbing requirements. An outdated, damaged or unsuitable device can then be replaced with an option appropriate for the connection rather than applying the same type of device to every property.
Backflow devices may be installed at commercial buildings, retail and hospitality sites, workshops, industrial properties, apartment complexes, strata developments, schools, care facilities and community premises. They may also be connected to irrigation or fire-service systems where relevant.
For occupied or operational sites, appointments can be arranged with disruption in mind. The team can discuss access, water shutdown requirements and the location of each device before attending, allowing staff, residents or site managers to prepare.
The plumber begins by locating the device and confirming its type, identification details and accessibility. They inspect its general condition and the surrounding installation, looking for visible leakage, corrosion, damage or anything that may prevent safe access to the test points.
Testing equipment is then connected to the device. Under controlled pressure conditions, the plumber checks how the internal valves and relief components respond. The device is recorded as passing or failing according to the applicable testing procedure. The water supply may need to be interrupted for a short period while this work is carried out. At commercial, strata or occupied premises, the customer should be advised before any interruption occurs.
If the device fails, the plumber will explain the fault and recommend suitable servicing, repair or replacement options. Work may involve cleaning components, replacing worn parts or addressing a leak. The device may need another backflow test after maintenance to confirm that it is operating correctly. Relevant test details and documentation are then completed.
Before the appointment, make sure the device can be reached safely. Remove stored items, debris or vegetation blocking access, and tell tenants, employees or other occupants that a brief interruption may be required. Keep any Water Corporation notice or previous test record available, and let the team know if the property contains several devices.
Testing obligations depend on the property, its water connection, the installed device and the assessed contamination risk. Backflow prevention is not limited to large industrial sites. A testable device may also be present at smaller commercial premises, residential developments or properties with additional water systems.
Common examples include commercial and industrial properties, strata and multi-residential developments, sites with fire services or irrigation systems, workshops using chemicals, and hospitality or food-processing premises. Devices may also be installed at medical, dental, aged-care or childcare facilities, as well as properties with rainwater tanks or alternative water connections. Water Corporation may identify some sites as requiring containment protection.
Containment protection is installed to protect the public water supply at the property boundary. Zone protection isolates a particular area or section within a property, while individual protection addresses the risk associated with a specific fixture, appliance or connection. A property may use one or more of these approaches depending on its layout and hazards.
