To protect health, state drinking water rules require public water systems to develop and implement Cross-Connection Control (CCC) programs. Under these programs, some water system customers (property owners) may have to install backflow prevention assemblies. Backflow assemblies must be tested by a certified backflow assembly tester to make sure they work properly. See below for useful CCC information.
FASTER PLUMBING is certified for backflow installation, inspection and repair.
Backflow is the undesirable reversal of the flow of non-potable water or other substances through a cross-connection and into the piping of a public water system or consumer's potable water system. This can render the public water supply undrinkable. Themechanism for preventing cross-connection is a backflow preventer assembly, which provides a physical barrier to backflow. The principal types of 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.
A cross-connection is any actual or potential physical connection between a drinking water system and any other non-potable substance (liquid, solid, or gas).
Backflow occurs when water or other substances flow in the opposite direction than intended allowing contaminants to enter the public water system or consumer’s plumbing.
A backflow incident occurs when biological, chemical, or physical contaminants enter the drinking water supply (under backflow conditions) via unprotected cross-connections. Backflow incidents may cause injury, illness, or death.
Backflow prevention assemblies are mechanical devices installed on water service lines (or at plumbing fixtures) to prevent backflow of contaminants into drinking water through cross-connections.
