Frequently Asked Questions

Clean drinking water flows in one direction: from a clean water supply to your home or business. Backflow occurs when this water flows backward: from your home or business back toward the clean supply. This can cause contamination of clean water supplies with things like chemicals and bacteria causing people to get sick.

Water flows through plumbing with the help of a standard pressure. Backflow most often occurs due a process called ‘siphonage’, where there is a disruption in the standard pressure within a plumbing system. If water pressure is too high or too low at either the water supply source or your site, then the risk of backflow is increased.

This depends on your property’s backflow hazard risk classification – low, medium or high. Backflow hazard risk classifications are based on the level of harm that could be caused to the public should a backflow preventer fail. Yearly backflow testing is required for devices classified as medium or high by an accredited backflow plumbing service.
