    How do I protect myself from backflow?


    How do I protect myself from backflow?

    "Since there are a variety of backflow prevention devices it really depends on the situation. These might take the form of an actual 'air gap' or a mechanical backflow prevention device such as a 'double-check' valve, which is required when installing a garden tap to prevent potential backflow of contaminated water into the water supply. The gap between the tap outlet on your kitchen sink and the spill-over level of the sink are designed to prevent backflow. The water regulations manual details all the situations and the required devices for each installation. There are numerous mechanical backflow devices and I would suggest consulting a qualified plumber or the water regulations manual itself when deciding on the type of backflow device required."

    "Backflow is caused by sudden water pressure drop or unwanted reversal of water flow instead of pushing water out of our taps, it is sucked back in"
