Febco 850/860 Backflow Prevention Assembly Disk Retainer Screws

Here we have a 1.5” Febco 850 as you can see the disk retainer screws for both checks have come loose and flowed downstream.

I am told the cone shaped object circled in yellow is a fix Febco designed that goes in front of the model 850/860 first check module. Its purpose is to help reduce the vibration that causes the disk retainer screws to come loose.
