Backflow Assembly Check Valves

October 9, 2011

Here we have a check valve out of a 2” Watts backflow prevention assembly.

The seat of the assembly has cut a groove into disk causing pieces of the disk to break off and flow downstream. This is usually a sign of Excessive Backpressure.

This check valve leaked and did not pass the annual backflow test.
