Doyle's Plumbing have had experience in testing, installing and servicing backflow valves for nearly 15 years. We have helped many businesses (industrial & commercial), body corporate and home owners with backflow prevention protection.

We can carry out an audit at your site and tell you where you need to install valves and what type of valves are required at your site.

We carry out annual testing of backflow valves, as required by local authorities, to the Australian Standard 2845.3 2010.

Backflow Valves

Backflow valves are required in domestic, commercial & industrial applications. In a domestic situation generally the
only backflow protection you need is one of the following:


1: Backstop valve- a non testable device fitted to your hose tap to prevent back siphonage through your hose into your drinking water. For low risk areas.

2: Vacuum breaker valve- a non testable device fitted to your hose tap to prevent back siphonage through your hose into your drinking water. For low risk areas.

3: Dual check valve- a non testable device fitted to appliances which use drinking water such as a dishwasher or water filter. These are also used on domestic watering systems. For low risk areas.

Most of these valves are not repairable.

In commercial & industrial applications much more reliable valves are use which are tested every year. These valves are one of the following:

1: Double Check valve (DCV)- these are used in medium risk areas where if backflow occurs minor illness can occur. This valve is fully serviceable and testable.

2: Reduced Pressure Zone valve (RPZ)- these are used in high risk areas where if backflow occurs serious illness or death can occur. This valve is fully serviceable and testable.
