I have heard of some saying their system can collapse the thin stuff if

you are approaching this situation just bleed a bit of air - yeah, I know
that isn't the idea but life isn't perfect at least on the cheap.
The problem with "just bleed a little air" is that you don't know you need
to until it's too late.
