So attempting to disassemble my non-functional Fiav,I eventually destroyed it.
So now it is off to our WTB section or Fleabay with fingers crossed.
What I have noticed on Fleabay is a 2 separate Fiav blockoff plates. One to retain the ISC the other without.
I understand the valves function, but question if I can get by without, as my climate here (Pacific Northwest) seldom stays cold for long... (just rain....)
Anyone with experience with a blocking plate, or am I best trying to hunt down a used working valve?
