Features & Benefits

Introducing the Blow Out Bonnet or BOB for short. This tool will completely change the way you winterize residential lawn sprinklers that have a pressure vacuum breaker (PVB). With this tool you will be able to save on average 15 minutes per winterization. Essentially cutting your time per job in half compared to previous blowout methods. BOB will allow you to almost double productivity while keeping labor costs the same.

The Blow Out Bonnet replaces the factory bonnet during winterization. Just simply remove the factory poppet and bonnet and screw BOB in its place. BOB has a 3/4" threaded hole in the top allowing you to use a 3/4" hose. This will provide 6 times the volume of air versus a 1/4" test port and 9 times the volume of air the 1/8" test port. It is designed to be used with an air compressor that produces over 100 CFM.
