During its April 1987 meeting, the ASSE Board of Directors recognized a plumbing industry need and voted to develop professional qualification standards for individuals involved with backflow prevention. Like the ASSE product standards, these professional qualifications standards established minimum industry requirements for backflow prevention assembly testers, backflow prevention assembly repairers and cross-connection control surveyors. This voluntary consensus series of standards was the first in the plumbing and water supply fields to set minimum requirements for a qualified professional.
Backflow prevention assemblies and devices, along with their proper installation, testing and repairing, have been an important part of protecting public health since the 1890s. During the past 100 years, the industry grew in many directions and philosophies. To prepare this standard, representatives from different regions and industry segments dedicated themselves to achieving a true consensus and thereby advancing the backflow prevention community.
This standard, the Series 5000, was first issued by ASSE's Board of Directors in 1990 and was approved as an American National Standard on Nov. 14, 1991. The 2009 revision of the standard series included Professional Qualifications Standards for Fire-Sprinkler System Cross-Connection Control Testers and Backflow Prevention Program Administrators.
