Sounds like a water system from a well? If so; could that gadget
interfere with the well-pump system?


Not sure what it's interfering with. It's intentionally putting a
small amount of water in the line, but it's causing a lot of
"chattering" in the pipes.

The water comes from the well, through the new aerator dohickey, to
the blue well tank, through a Kinetico water softener, and then for
hot, the water goes through a Rinai on-demand system.

I've put too much money into this system for it to not work right. :P
