Residential water pressure is usually maintained at a standard level to keep the water flowing in a specific direction through different areas of a home, for example from the shower to the toilet to the sink, etc.
Any unexpected drops in the water pressure can cause a backflow, i.e. water being drawn backwards into the water main. This can cause contamination to the drinking water supply.
Backflow is prevented using backflow preventer valves, which are installed at specific locations throughout the plumbing system where there is a risk of contaminated water entering the system. These prevention devices need to be tested on a yearly basis as regular maintenance to ensure that they’re in optimal working condition.
Any malfunction could lead to unsafe drinking water entering your household water supply, which could pose health risks for your family.
The regulations by Sydney Water for backflow prevention stipulate that backflow prevention devices must be installed and tested upon installation and every year after, by an accredited backflow plumber. The test results must then be sent to Sydney Water by the accredited backflow plumber within two days of the test.
Besides offering a locally-based 24/7 plumbing service for residents and businesses across Sydney’s North Shore, Northern Beaches, Eastern suburbs, and Inner West, Harrison from The Plumber Next Door is accredited in testing backflow devices by the Train N Trade, a registered training organisation in Sydney.
