Find a Master Plumber for commercial backflow support
Keep backflow devices working as intended
A backflow device that is leaking, discharging, damaged or not holding pressure correctly needs informed attention. In commercial and industrial settings, the practical challenge is often bigger than the device itself: access arrangements, shutdown restrictions, tenant activity, asset records and site controls can all affect how repairs and maintenance are planned.
Commercial backflow repairs and maintenance focus on testable backflow prevention devices used to protect the potable water supply from contamination. These devices have moving parts, seals, springs, check valves, relief valves and test points. Over time, components can wear, foul with debris or stop operating correctly.
When backflow valve servicing may be needed
Regular commercial backflow maintenance may be arranged as part of asset upkeep, or it may follow a test result that identifies a fault. A device may also need attention after it has been repaired, maintained or replaced.
Useful reasons to seek assistance include:
- a device that is leaking or discharging;
- a device that fails field testing;
- visible damage to the assembly or surrounding pipework;
- concerns that the device is not holding pressure correctly;
- debris or fouling affecting internal components; and
- a need to arrange ongoing servicing or testing records for a site asset.
Testing confirms whether a device is still protecting the drinking water supply as intended. Repair work and testing are connected but distinct tasks: a licensed plumbing contractor installs, commissions and repairs backflow prevention devices, while an accredited backflow tester can test testable devices.
What repairs and maintenance can involve
The work required depends on the device condition and the result of testing. Backflow preventer maintenance can involve inspection, field testing, fault diagnosis, cleaning and repair of components, with testing after relevant work has been completed.
- commissioning tests after installation;
- annual field testing of registered testable devices;
- testing after repair, maintenance or replacement;
- cleaning strainers or internal components;
- replacement of seals, springs, check valves or relief-valve parts;
- diagnosis of a failed test result; and
- repair or replacement of leaking, damaged or non-compliant devices.
For boundary containment backflow devices in Western Australia, Water Corporation requires registration and testing at commissioning, followed by testing annually or after maintenance. Test reports must be submitted through Water Corporation’s online lodgement system by an accredited backflow tester permitted to test those devices.
Plan the work around your site
Backflow work at a business, facility or industrial site can require coordination with building operations. Before engaging a plumbing business, identify whether water can be isolated and whether a shutdown window, access arrangement or authorisation is needed. This gives the plumbing business a clearer starting point and helps them understand operational constraints before attending.
Details that can help with an enquiry
- the device make, model, size, serial number and asset ID, where available;
- the device location, plant-room reference and access instructions;
- previous test reports, service records, manuals or drawings;
- Water Corporation registration details where relevant;
- photos of the valve assembly, labels and surrounding pipework;
- whether the device is leaking or discharging, and when the issue began;
- whether water isolation is possible and any business or tenant shutdown restrictions;
- site induction, permit, parking, loading and permitted-hours requirements; and
- the person authorised to approve repairs if the device fails.
For industrial operations, it may also be important to identify process impacts, safety permits, environmental controls and critical production constraints.
Brands and equipment you may encounter
Asset labels, previous reports and supplier records may refer to a range of backflow products, components, pipe systems and test equipment. Examples customers may encounter include RMC, AVG, Watts, Febco, Zurn, Wilkins, Apollo, ValvCheQ, Bermad and Ames. Supply channels and related products may also be associated with Reece, Galvins, Tradelink, Enware, Galvin Engineering, Kembla, Viega, Iplex, Vinidex and Rehau.
Device make, model, size and serial number can be particularly useful when arranging commercial backflow repairs. Test instruments may also appear in site records under names such as Testo, Fluke, Rothenberger or RIDGID. These are examples only; the equipment present at a property and the condition of the device determine the information most useful for servicing discussions.
Choose a plumbing business with the right information in hand
Find a Master Plumber is backed by the Master Plumbers and Gasfitters Association of Western Australia. It connects customers with Master Plumbers and plumbing businesses associated with Master Plumbers WA, helping customers make a more informed choice of plumbing business for their property or project.
When comparing options for backflow repairs and maintenance, explain the device issue, site constraints and the outcome you need. Ask whether the plumbing business can consider the available device details, access conditions and timing restrictions before work is arranged. Clear records and a nominated contact person can be especially valuable where an asset is managed across multiple stakeholders.
