Back Flow Prevention
Backflow preventer assemblies are utilized to protect our natural resource, safe drinking water.  Backflow prevention is required on applications in which there exists a possibility of contamination of the public water supply from a water user, commonly referred to as a "cross-connection".  Potential cross-connection hazards are found in potable, fire-protection, irrigation, and industrial water lines.   Codes and jurisdictions require a backflow prevention device where these hazards exist; consult authorities for specific approved applications.

There are several different types of backflow preventer devices depending on the application:
