This is strange. Several days ago, all of a sudden, each time we run water, flush, etc. it sounds like there is air in the lines. We have been hooked up for almost a year, so nothing has changed. It not a clanking, but more like a loud humming or buzzing. The pump is not on. I have checked the water connection and it all seems fine. Anyone ever hear of this, (no pun intended).
