It's going to be difficult getting the required test pressure using
water from your garden hose.  I would think the best method would be
to pressure test with air whilst submersing the tank in a water tub.
Basically, the same method they use to fill SCUBA tanks (not only is
it safer, but it keeps the tank cool during the fill).

Cheers,

Jeff
