I have to admit - I do still have a fear working with tanks… Why
is it that many times after I shut off the valve and completely
bleed the hoses, I go out to the tank the next day and the regulator
pressure is back where it was when the tank was on, even though the
valve is shut? Is it because the hoses were not “completely” bled
(even though I thought they were), or is there something wrong with
my shut off valve?
