This happened to a Sears floor jack I used to own. I could pump it up but
when it reached a certain point it would sink to the ground as if I had
opened the valve completely. It was fortunate I was using jack stands when
I the problem first presented itself since I was underneath a 3500 pound
sedan at the time. They mean it when they say "don't ever get underneath a
vehicle supported solely by a jack".
