Review on Febco 905 212 Breakers Backflow Preventers by Dustin Gabrielle

New model to replace old, fragile plastic valve parts. This two-piece replacement fixes the flimsy three-legged spider valve and piston. The ancient spider absorbs the full power of the water/ice as it expands. The new lower piston transfers the load to the spider's strong threaded bottom. Wow, why didn't I dare to spend the extra money to replace two parts? Much better that the metal parts of this expensive FEBCO 765 check valve should last longer.
