BOP Program Statement 1605.01 § 10

Design, construction, renovations, and maintenance of an institution plumbing system must meet

applicable plumbing codes.

Backflow Prevention. Backflow prevention devices or assemblies must be installed in the

potable water supply to prevent pollution or contamination from cross-connections, in

accordance with federal, state, and local regulations. Each cross-connection will require a

different type of backflow prevention device, appropriate to the degree of hazard, as dictated by

state and local regulations. Non-testable backflow preventers will be installed wherever there is a

low pollution hazard from the potential for contaminants to enter the drinking water system (e.g.,

threaded hose bibs, faucets, and sprayers with rings). If state regulations specify what constitutes

a low pollution hazard, those regulations will be applied.

If there is no state or local regulatory guidance as to the type of backflow prevention device to

use with varying degrees of hazard, default to the International Plumbing Code, International

Code Council.

Backflow prevention assemblies must be tested by a certified tester at installation, repair, or

relocation, and at least annually thereafter. Inspection is documented using a state-approved

form. If a state form is not mandated, use the form provided by NFPA 25.

Annually, the SA reviews backflow assembly testing records to ensure each assembly was tested

by a certified tester in accordance with federal, state, and local regulations.
