backflow prevention & testing

book your backflow testing

IQP (Independent Qualified Professional) perform backflow testing and prevention. Auckland Plumbers Group has trained individuals to carry out tests and install preventers.

Prevention devices may be testable or non-testable. Their use in a particular situation depends on the degree of hazard. Non-testable devices, for example, may only be used on low-hazard-rated systems.

A testable device requires testing upon installation and at regular intervals to the Acceptable Solution G12/AS1: 3.7 Testing standards. You should check your non-testable devices every two years maximum.

Risk Classification (3 types)

HIGH
High-risk sites are properties that use or produce products of a toxic or bacterial nature that may cause death or serious illness if leaked into the main water supply.

MEDIUM
Medium Risk sites can endanger health if backflow contamination occurs.

LOW
Low Risk sites are properties that could cause a nuisance by colour, odour, or taste but do not endanger health.
