    We have always installed Watts RPZ backflow preventers - usually 3/4" for residentials. While talking to my supplier, I learned that a Wilkins RPZ of the same size is substantially cheaper - $40 cheaper to be exact. I just wanted to get some input on why that is. I've had very few problems with the Watts that we put in & would be willing to try Wilkins provided that they are not prone to problems.

    Wilkins seems to make decent stuff. They have a durable PVB (brass bonnet) and the RPZ seems to be okay. They probably are still using the same casting for both 3/4 and 1 inch RPZs. Their RPZ will need the same sort of disassembly that a Febco 825Y needs, come fall.

    I don't like the Wilkins or Watts because I can't find any damn repair parts for it around here. At least for the RPs. Right now I need a relief valve for a Watts 1" 009 RP. No suppliers here or one in Denver carry it. Has to be ordered.
