We have new home with a drilled well (over 450 ft deep) and a forced hot water heating system. There is a knocking in the bedroom pipes. The plumber has bled the pipes three or four times already. It is much better but the knocking keeps coming back. The plumber says he has done all he can and the fact that the air keeps returning means there is a crack in the well lining or the line running from the well to the house. The well company is skeptical (husband is calling them back today but it sounds like they are pointing the finger back at the plumber.) Anyone have any experience with this?
thanks much
