Flooded backflow prevention assembly vault.

We are in the process of pumping out this flooded vault in Fife with a Febco DCDA fire service backflow prevention assembly. Our pump puts out enough water for my son to build waterfalls and have leaf races in the water current.

The ¾” Febco 805YB failed the backflow test so we cleaned it and rebuilt it with new parts; check valve #1s seat had cut into the disk. This backflow prevention assembly in Fife passed the test after the repairs were made.   Click to Enlarge.
