Wilkins 3/4" 420 Freeze Resistant PVB Pressure Vacuum Breaker Assembly Backflow Preventer 34-420 with Integral Anti-Freeze Relief Valve

Purchasing a completely new assembly it came "Ready to Install" Took my time and within 1/2 hr this is the result...My neighbor had his done by a Lawn company and it cost him 3 times the cost of this amount I paid. Yes, I had to cut the old PVC elbow off and attach a new one with a small extended PVC piece but if you know the basic PVC attachment techs it is an easy job. Great Item...

Great replacement for my old valve. Good solid casting and valves are nice and tight. Worth the extra money for freeze resistance if you are in snow country.

Replaced my old unit, fit and function as expected.
