strange noise from water lines

#1
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).

Do you mean that air comes from the faucet or toilet with the water? Could there be air in the water from the water supply? If you are sure that it is air, try disconnecting the water supply from the RV and run the water to see if air comes out there. It could be that work has been done on the water supply that introduced air into it.
