Who is Mark...here is his reply to someone needing help on
getting air out of a system...
You must think like water, grassshopper....
Close your eyes and think of yourself as being the water inside
the pipes. You must enter the system from wherever you're
introduced under pressure, and you must flow in a proper
direction, moving as quickly as you can, sweeping air in front
of you, pushing it out of each branch like a long, liquid
piston. You're trying to get to the point of no pressure, that
being the outlet, from whence ye shall fall.
Remember, you are wet, lazy and stupid. It takes closed valves
to show you where you NEED To go, not where you WANT to go. You
start by chasing the air out of those lines that are closest to
your source of point of discharge, then start working your way
upward and outward as you go. You know, that air is a wiley
coyote, always seeking higher ground. In fact, you may have to
stop "chasing" him, and you may have to jack the pressure up on
him to make him rise to the top. Once there, let him out
Think like a fluid...
Yep...now ya know why he's one of the best.
