Thanks for the tips. I cannot easily plumb soft hose into our main water pipe because it's buried several feet underground. Perhaps a flexible pressure hose plumbed into the 3/4 inch pipe 3 feet above the CSV may help. I may be chasing after phantoms, though. We'll undoubtedly survive the noise, which is less noticeable since the pump isn't running 8-9 minutes after drawing a glass of water when the tank is empty. Oddly, the basement noise is almost inaudible. It's much louder on the first and second floors -- so I expect pipe turbulence is resonating our wooden home like a bass viol. Perhaps some rubber gaskets instead of metal pipe hangers will also help, but I don't know any way to reduce harmonic contact inside first and second story wall joists.
I reinstalled our pressure switch the same way it was originally installed by our well contractor last summer. I haven't noticed any switch bouncing, but will remain vigilant.
Curiously I noticed today that our pressure valve seems to operate differently when only hot water is being drawn. When the dishwasher is running, the pressure keeps cycling between 40-50 PSI and the CSV never activates at 57. The system has probably always done this and I just never noticed. I can't easily explain the behavior. I wonder if it has something to do with 1/2 inch pipe running to the dishwasher, versus 3/4 inch pipe in the rest of our home. I made minor adjustments to the pressure switch and will observe what happens.
