Frequently Asked Questions
A backflow preventer is a device used to protect potable water supplies from contamination or pollution due to backflow, the undesirable reversal flow.
A backflow prevention assembly is a testable backflow device which uses spring loaded check valves to prevent polluted or contaminated water from flowing backwards. Some assemblies eliminate backflow by discharging used water to the ground.
Pollution of the water supply does not constitute an actual health hazard, but the water may taste, smell, or look undesirable.
Contamination of the water supply constitutes an actual health hazard, with the consumer being subjected to potentially harmful water borne disease or chemicals.
Two things can cause water to flow in reverse: backsiphonage and backpressure.
The reverse flow of water due to negative pressure.
Back-siphonage is created when there is a sudden drop in water pressure in water mains due to water main breaks, nearby firefighting efforts or high usage.
A reversal of normal flow due to downstream pressure being greater than supply pressure.
