      A:

      It goes before, so that the preventer can be replaced or serviced at a later date if needed.

      A:

      The master shut off valve goes before the back flow preventer. This way,
      the back flow preventer can be changed or repaired. Make sure you install
      an expansion tank in the system to prevent overpressure from your water
      heater. This is a necessity with backflow preventers, otherwise as the
      water expands from the water heater, the system pressure will increase until
      the relief valve on the water heater opens.

      A:

      The valve should be replaced when it fails - the only way to verify this
      with this style of valve is to install a ball valve with a drain between
      the valve and the water supply and check the valve periodically. Most
      people install the valve and forget about it.

      In my opinion it is fine as long as it works.
      But there may be local codes for the maintenance of this check valve.

      A:

      Mike,
      I am not a licensed plumr , but under normal conditions this valve should give you years of trouble free service, as they are of brass construction and have a dual ck. valve inside. I have 3 installed in my system, and I soldered them in place (another words they are permanently installed), you don't have to go this route, they make them threaded so you can remove them if you have to, its your prerogative . If you do sweat it in, first take the valve body apart, keep track the way you desassembled it and put these pieces aside for now.  Clean  both sides of the valves brass body with an internal  metal brush, apply flux, solder it in place, let cool, apply plumbers grease to the removed "o" rings, and the inside of the valve's body you put aside before, and reassemble it in the removed order. Tighten the brass nut that holds both valve body parts together, pressurize & ck for leaks. I believe Watts also sells the internal packing if you have to replace them.
      Hope this helped you a little, and as I  mentioned,  I am not a plumr by profession, best thing, contact Watts for their advise, they are the ones who make the valve.
      Good luck.
