You can check its condition by blowing it up with the manual mouth piece
leaving it for 24 hours , there should only be a slight air loss . also
check the cylinder is ok. Unscrew and visual check no tiny hole , or signs
that it may have leaked. A chemist can weigh it to see if it is still the
filled weight stamped on the cylinder
