Febco 765 Repair Kit 905-212 for 765-1 Pressure Vacuum Breaker Backflow
How to Replace the Bonnet and Poppet (you should always change both):
Turn off the water supply (Warning: Failure to Assure the Water Pressure is Relieved can cause Harm!)
Close water supply side ball valve first
Go to the sprinkler controller and manually start each zone or section valve by manually starting the sprinkler system. This will relieve the water pressure in the PVB. Then turn off the manual operation of the sprinkler system.
Close second ball valve (on outlet side of PVB)
Make sure that you have relieved water pressure by opening test cocks on side of PVB
Place large O-Ring (included in kit) around Bonnet
Apply lubricant (included in kit) to gasket
