Backflow testing and prevention FAQ’s

What is backflow prevention testing?

Backflow testing is a procedure used to examine a plumbing system to ensure that the drinking water is not being contaminated by dirty water flowing the wrong way through the system. Backflow refers to water running backwards through a water system and contaminating the drinking water supply, making it undrinkable.

Why is backflow testing required?

Backflow testing is required for occupational health and safety reasons. Backflow can cause water contamination which can result in serious illness. Backflow prevention devices require testing upon installation, when repaired or relocated, or at the least on an annual schedule. Some high-risk systems require quarterly testing.

How to test a backflow device?

The backflow prevention testing procedure includes a mechanical plumber opening and closing valves to check for any abnormalities in the system and then forming a report. Once the plumber has done the backflow prevention device inspection and maintenance report, the report must be submitted to the relevant water authority.

How often should a backflow preventer be tested?

Back Flow Valves must be tested every 12 months. All results must be sent from your accredited plumber to the relevant water authority. Businesses are responsible for installing and testing their backflow prevention assemblies, as backflow and contaminated drinking water could leave them open to liabilities.
