Richmond Hill's Backflow Preventer Test Report, the Maintenance & Operations Division form under Backflow Prevention By-law 125-14 for recording the test of a single backflow preventer. It captures the facility, owner, qualified person and test kit calibration, the device make, model, serial number, size, orientation and install date with its building permit number, the system and type of isolation, and initial or annual test readings for RP, DCVA and PVB devices. Repair and retest sections follow, then the qualified person's certification. It pairs with the Cross Connection Control Survey Report.
