    Thanks Pete, I am working on a project where this will come in handy for spec purposes.

    Good information, but, as with a master valve, it should be brass with all the work they get.
     
  4. If the guts or working parts are plastic then I'm not sure brass is a big improvement. On ball valves and nozzles brass is a big improvement for sure. Mark my word that in ten years you will be installing plastic backflow devices other than avbs and it will be acceptable to code.

  8. Everyone of those I ever ran into was put below grade. I can't imagine too many municipalities would allow those.

    That Wilkins 375 looks interesting. What would be cool is after you remove the guts for winterizing then another type of insert can be put in to take your air hose and blow out the system.

    Actually that is exactly how they are designed. But the insert is an add on. It replaces the guts with an insert with two 3/4 inch threaded hole for air hook up.
