Air in system??

Ok, I just need someone to confirm what I know... Air in Lines

Deep well, pressure tank tests ok, pump does not cycle, system holds pressure.
Just started having air in lines, does not seem to be a water level issue??

There looks to be a check valve prior to the tank so it seems I only have 3 possible sources.. leak at pitless adapter, hole in pipe/joint, bad foot valve or mutiples of any....Am I on track or did I miss something??

Thanks
Pat

You never told us what kind of pump/tank you have.

bob...

25 year old Burke submersible? and a 20 gallon Amtrol baldder?

You sure got your moneys worth out of that equipment.

If you remove the un-needed check valve from up top, you might be able to hear water down the pitless adaptor or can hear water moving through the pipe with the help of a screw driver with the tip on the pipe and the plastic handle up to your ear. Kind of like a poor mans stethoscope.
