What is Backflow?
We often find in residential homes that, dirty water from the hillside pool and/or the lawn irrigation sprinkler system will back-siphon or back-flow down the hosepipe and into the clean water tank. To prevent this from happening, the house's external tap should be fitted with a backflow prevention device.
What is a backflow prevention device?
A backflow preventer is a means or mechanism to prevent backflow. The basic system for preventing backflow is a mechanical backflow preventer device, which provides a physical barrier to the backflow of water to prevent cross contamination issues. The main types of mechanical backflow preventer are the reduced pressure principle assembly, the pressure vacuum breaker assembly, and the double check valve assembly. A secondary type of mechanical backflow preventer is the residential dual check valve.
What is a cross-connection in my water system?
An example is the piping between a public water system or consumer's potable water system and an auxiliary water system, cooling system, or lawn sprinkler irrigation system. A cross-connection is any temporary or permanent connection between a public water system or consumer's potable (i.e., drinking) water system and any source or system containing nonpotable water or other substances.
