I am looking into a new machine that is 7 GPM at 3000 psi. This a general pump belt drive unit. They say that a buffer tank will not work with this unit. They say that all pumps need at least 20 percent more feed than what the output is rated at or I would need at least 8.4 GPM. Just when you think you have learned about tanks, and pumps, out put and office size and fan degrees it puts me back at square 1. With 1"plumbing and 1" fill line from house, starting the job with 100 gals, and 1" to the pump why will this not work? Confused! Thanks.
