A backflow preventer not only protects the drinking water system in our house but is also an important part of the supply network outside of our 4 walls, as the house’s own drinking water could be polluted and the utility wants to protect other water users from it. A backflow preventer must be maintained annually to ensure drinking water quality for utilities and homeowners.

Backflow is the unwanted turnaround of the flow of water, water mixing with pollutants, it goes directly to the distribution pipes of your potable water system. Backflow happens due to cross-connections, if the clean water pressure is lower than wastewater, contaminants can get into the drinking water system. When there is a pressure drop, contaminated water is drawn backwards into your water system.

What does a backflow prevention device do?

Backflow preventers take on the task of allowing water to flow in pipes only in one direction. If the flow direction reverses, or if a reflux pressure arises, they close automatically. If the flow direction changes again in the desired manner, the backflow preventer opens again by itself.

Our plumbing services also specialise in backflow prevention testing as well as its repairs. If you have received a letter from your council regarding the testing of your backflow preventer, just give us a call and we will work out the rest for you.

Type of the backflow prevention device depends on the hazard level the facility is classified in the Hazard Code provided by the state. For example, a ‘moderate hazard’ might require a Double Check Valve Assembly device, and a ‘severe hazard’ might require a Reduce Pressure Principle device.

General Plumbing Services is aware of the legal penalties you might receive for a faulty backflow prevention device or not having it at all. That’s why we are offering you the installation of backflow prevention devices and their yearly testing. The real penalty, however, is the sickness and diseases that lack of backflow prevention might bring about. Don’t neglect this simple installation and ensure your water is clean and free of toxicants.

Your local government body may, at any time, require you to get your backflow prevention device checked, tested and repaired if needed by a licensed service. To save yourself time when this happens, make sure you got our contacts saved for the day.
