Well.... I ordered up a relatively cheap hand pump/water reservoir contraption complete with gauges for pressure testing plumbing. The pump part is basically the same as the hand pump on a hydraulic jack or press. It goes to 800 PSI, but easier to control than a pressure washer. I figured it was worth the investment, because...if it works (without any drama) it is an art form I would like to explore.
