pump problems and Rotor Poll
Ok Rusty, now you have me a little
confused. Your rev-2 upgrade seems a lot like my current system. A
pressure cap (rev-2) at the rear side housing outlet (highest point in the
system) is just like having a small tank there with a pressure cap on it (my
current system). I would prefer not to make the change if you think there
is nothing wrong with the current system and my problem lies elsewhere.
To AST or not to AST, that is the question.
Sorry Dave, I think I wasn't very clear
about where my new pressure cap is. It's at the top of the
water pump housing, as you can see in the pic. The way I had it
in the rev-1 arrangement is actually more ideal, but I ruined it with some
large loops of hose that tended to trap air. That's probably the
only reason my rev-2 arrangement seems better. I would urge
you to continue with your proposed change.
Rusty (AST's are never bad, if you have
room for them)
