My bet is
that you have a small leak in the system. If the seal stays inflated until you
flip the switch to deflate it, I'd look first in the line/connections between
the pump and the check valve, but the whole system needs a good leak check;
that's the most likely--and easiest to
find--malfunction
I concur with Bob's assessment. I had a very tiny pin hole leak that had
the same charateristics you are reporting. Fixed it with a little RTV.
