Backflow testing

Qualified backflow prevention testing

Backflow prevention devices legally require annual testing by a licensed plumber to ensure they’re functioning correctly and adequately. In certain conditions, water can travel from a premises back into a water main when there is a pressure indifference in a water supply. This can result in contaminated, or unclean water being drawn back into the domestic water supply causing people to become ill from drinking the contaminated water and historically, many cases of water contamination have been traced to defective valves in business and industrial environments.

Backflow testing certificates

Brisbane City Council, Moreton Bay Regional Council, Redland City Council and Logan City Council each maintain a register of all backflow devices registered within their local government area and, as approved technicians, we provide comprehensive backflow testing and certification reports in line with the Queensland Government’s maintenance policy. We also provide installation, maintenance and repair for all backflow devices and thermostatic mixing valves.

Why backflow testing matters

Backflow tests

Backflow testing is a process that is used to ensure that water flows in the correct direction through a plumbing system. This is done by creating a watertight seal at the end of the test piece and then filling the system with water. If the water level in the system drops, it indicates that there is a backflow problem.

Backflow testing is important because it can help to prevent contaminated water from flowing back into the potable water supply. This can happen if there is a break in the plumbing system or if a backflow valve fails. Backflow testing can also help to identify potential problems so that they can be fixed before they cause any damage.

Direct & indirect backflow prevention

There are two main types of backflow testing, direct and indirect. Direct backflow testing is the most common type and is done by attaching a test piece to the end of the plumbing system. The test piece is then filled with water and the water pressure is monitored. If the pressure drops, it indicates a backflow problem.

Indirect backflow testing is done by attaching a test piece to the end of the plumbing system and then filling the system with water. The water level in the system is then monitored. If the water level drops, it indicates a backflow problem.
