Standards for Backflow Prevention Device Installation
A backflow preventer installed on a water supply system in Oklahoma must adhere to ASSE standards for construction, installation, maintenance, inspection, and testing. The Oklahoma plumbing code mandates that certain assemblies be tested immediately after repairs or relocation, and at least annually.
Requirements for Tulsa City Compliance Backflow Certification
For lawn irrigation systems, Tulsa city guidance requires annual testing by a qualified professional. Furthermore, the double check detector assembly design working pressure must meet a minimum of 150 psi, according to city water-meter specifications.
