Took one of the "bad" heater valves apart to see what causes these to fail.
Device is fairly simple with only a sliding gate to control the flow. The valve tooth rack actually moves the valve stem....but from looking at it I think most of everyone's leaks comes from the wear of the same circulator 0-ring which seals the valve stem....about a $.05 item in my book. So other than this stem o-ring, or the o-rings for mounting the valve there is not a lot which can cause leaking. I was going to find a replacement o-ring for the "failed" unit I have but have not got to it....
