Fire Service Backflow Assembly in the

RPBA failed. Upon Inspection the plastic poppet
had actually melted. Most likely from using too much
air pressure during
winter blow out.
Assembly failed. The rubber disc is cut and no longer seats properly. Has to be replaced.
New Install that was 2 feet underwater and completely covered in mud and rocks upon arrival. Had an irrigation box been around the assembly this would not have been the case.

Two Toro RPBA assemblies in the mechanical room of a dentist office. Have never seen this type before. There is an inline filter seen in upper left and the
