I need some help from any resident plumbing experts. I just built a new house, and I've got a problem that neither the plumber or the company that installed the well and water pump can figure out. Whenever the pump cycles on, there is vibration that I can hear(and feel) through the house, mostly in the master bath area. There was a loud as hell vibration behind the shower enclosure because the vibrating pipes were hitting the enclosure and amplifying the sound. Pipe wrap fixed that, but there is still this aggravating low grade hum - it almost sounds like a power transformer. I looked at the pump, and there is a normal vibration coming from the pressure switch, and I guess that is getting amplified through the pipes. Anyway, does anyone have any idea how to fix this? I was trying to think of some sort of vibration dampener on the pipe that enters the house, but if it's all coming through the water in the pipes, I don't figure that would help.
