Bye Bye Barnacle is currently the only proven permanently installed flush unit on the market

Due to the problems in maintenance of removing barnacles from plumbing, air-conditioning and refrigeration heat exchangers, AugustWorks LLC has engineered and developed a flush unit called Bye Bye Barnacle (patent pending) which is permanently installed in the mechanical space of your vessel. This ensures a trouble-free maintenance experience. With Bye Bye Barnacle, the systems need to be flushed every 1 ½ months to avoid buildup of marine growth especially in warm waters and warmer climates. The flush unit is plumbed into the supply and return manifolds of the air conditioning and refrigeration systems. The flush unit is plumbed to on board fresh water system for filling and pumped overboard for draining contents overboard. Discover why F&S Boatworks, Weaver Boatworks, and Hinckley Yacht Services rave about this latest innovation in flush systems.

F&S Boatworks

Since 2003, I have been serving as a mechanic with the all the mechanicals throughout the building custom sportfish boats for F&S Boatworks. It was during this time that we discovered a need for an AC Flush System Unit that could be permanently installed in the mechanical space of vessel. In addition, we wanted to make come up with a simple operational unit in which we could flush AC Systems. From these ideas, the Bye Bye Barnacle Flush Unit was developed.
