My well pump (indoor, on top of the pressure tank) has started to squeal
when it runs. My gut thoughts are
1. Pump going bad.
2. Air getting in the line.

Any thoughts?
How to test?

Sound like the motor bearings are going out. Don't know how to test it, but
our pressure tank pump lasted around a year after it started getting really
loud.
