Hey guys looking for some suggestions. I am getting lots of air in my water lines in the house. We are on a well with a bladderless tank. I have checked for leaks in everywhere that I can access and have found no sign of leak. I replaced the snifter valve on my well system and drained and repressurized the house several times and I am still getting air in the lines. Does anyone have any suggestions as to what to try next or something that may be causing it that I am overlooking? Thanks in advance for the help.

Could be many things. I recently had the issue and took the cap off of the flusher in the toilet tank and flush the system. Fixed mine yours could be more complicated. I would start with turning all the water on and keep everything including dishwasher and washing machine on. Turn on all outside spigots as well. Then turn system off and back on and let water run a few minutes.

Sounds like you have a backflow valve that's draining back into the well. There should be 1 near the tank and the other one unfortunately is at the bottom of the well, it's called a foot valve.
