You probably have a leak in your system.  You are generating a very
small volume of gas and a very small leak can kill your pressure. The
most likely place is your seal at the top of the bottle.  I found the
best thing to use is a rubber stopper with a small copper, brass or
glass tube pushed through it.  Push an air line over this tube to
complete the connection.
