Hi All,

Put in a new well but the tank is getting waterlogged once a month. A
plumbing supple pro tells me that I need to drill a 3/16" hole in the
drop pipe (below ground) so that a slug of air will be delivered to the
tank every time the pump turns on. A check valve was installed directly
above the submersible pump and a second check value was installed between
the well cap and the tank.

Does drilling a hole in the drop pipe make sense to you?
