Loud water pump and possible solution?

Thanks. All great advice. One thing not mentioned is that the tank ALSO delivers a more consistent and uniformed pressure. It is a place for the pressure to build up. But, I will say, these pump don't seem to have the issues that well pumps do, with that roller coaster effect of pressure, so may be moot.

In any case, it seems this is more common knowledge than I thought. DANG IT. And here I was trying to impress all the old timers with some great, newbie insight, just to find out its OLD NEWS!
