The water supply is way overkill in this case. I have a 20hp 3Ph centrifugal pump that I bypass a lot of water back to the 1550 Gallon reservoir to maintain 45 psi line pressure--I can and have cranked it up to 65psi+. It doesn't work that way with a Superflow anyways. The SF has a suction inlet which uses a little impeller to fill the absorber . You should be able to dunk this thing in a lake and have the absorber work properly. This particular model (871) absorber is rated for 2500 hp/2000lb/ft and so is the load cell. Thanks for the questions though Kevin. J.Rob
