Homeowner here. Not a professional. Trying to pick a blackflow preventer to replace one that's worn out (10 years). In the lower price range, I found:
Conbraco 4A-505-A2F 1 in. Freeze Resistant PVB Backflow Preventer,
Watts 800M4QT 1 in. PVB Backflow Preventer,
Wilkins 720A 1 in. PVB Backflow Preventer.
What, if anything, is the difference among these? Is one a better quality than another? Which would you choose, and why?
Thanks in advance, Jerry.
