Backflow – The Danger Zone

Backflow occurs when used water from a dirty source flows backward into the pipes. It may carry contaminants like chemicals, oil, bacteria, mud, and debris that can harm people's health. Contaminated water can pose serious risks and illness.

Backflow is more likely to occur:

• If there's a drop in pressure in the main, for example, during a main break.
• If water pressure at the property is higher than at the main, for example, if a pump is operating on the site.

There Are Two Types of Backflow

• Back-siphonage: A drop in pressure (like a fire hydrant opening) creates a vacuum that sucks contaminated water in.
• Back-pressure: Contaminated water pressure is higher than the clean water pressure, forcing the dirty water back.

Contaminants may enter the drinking water by:

• Faulty plumbing
• Hoses submerged in buckets, tanks, toilets, or pools

Mandatory Testing – The Core Problem

• You must engage an accredited plumber to test your device yearly to ensure the drinking water is being protected.
• Devices will fail over time: internal components like springs, seals, and seats can break, wear out, or become fouled by debris and sediment.
• A failed device looks normal on the outside but offers zero protection against contaminated water entering the public supply.
• These devices are compulsory. They protect your water quality and the health of people using it.
• Backflow containment prevention devices stop water flowing backward into other fixtures such as drinking taps and other hygienic fixtures.
