This is a typical Wilkins 950XLT
assembly used for residential irrigation.
Proper new install of a Watts LF009QT RPBA
appropriately tagged with test report.
Anatomy of a Backflow Valve
Proper install service for a Boiler
Fire Service Backflow Assembly in the
Space Needle Basement Mechanical Room
Pumping out a flooded vault.
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.
Hired to repair / replace a failed Febco 850
irrigation DCVA. Debris restricted the
rubber disc from seating properly. Easy fix.
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 two new RPBA installs to the right.
