Review on 🔧 Revive Your Febco Device with the 905111 Rubber Repair Kit: A Comprehensive Solution by Issac Smart

Great little kit. In addition to the black rubber main diaphragm included in this kit, I cut out the center of the old diaphragm, made a ring (extra gasket) and doubled the new with the old. As a result, more rubber material can be compressed and the two halves of the BF-Preventer are sealed better. I think the four screws holding the two halves together are not enough. There should be 5-6 of them, which is why I doubled. All other components of the kit fit perfectly. No leaks! Super easy for DIYers. Highly recommended.
