Riverside Public Utilities prints on this roster: only test reports from the certified testing companies below will be accepted; all others will be denied. The older 6.3.25 PDF is superseded by this 1.6.26 file.
Every company below is copied from RPU’s Approved Backflow Tester List dated 1.6.26. This page is a local snapshot, not the live roster.
Blank phones or emails are blank on the PDF (for example COSCO Fire Protection Inc. has no phone). None were invented.
The official file does not mark fire-line testers. Two red rules in the PDF are footer lines, not row highlights.
