Head - Raritan PHII outlet connector bowed

[thinwater]

It might worth considering that Raritan may have (inadvertently) caused this problem by changing the spec on their joker valve by using a harder material for the flange "gasket" part that gets squeezed down. Our older Raritan PH2 models did not have this problem, and I sort of recall that the whole flange tightened down flat. Possibly, Perhaps,

I used to like Raritan joker valves in other heads.

BTW, Jabsco joker valves fit Raritan, I believe. Maybe try that. They are softer, but they also do not last as long. Neoprene vs. nitrile, at least in the past.
