With water in the tank, the air pressure is 46 PSI. I suppose it
should be higher, right?

What should the air pressure be? I could try pumping it up some more
now that there is water in the tank.

Replying to the previous two posts:

Your pressures with water in the tank are correct. The pressure
switch doesn't care a wit what your pre-charge is, it turns on and off
when the tank reaches the settings. Yes, it is a common
misunderstanding about the pre-charge, i.e., if I have 11 psi empty
and pump shuts off at a 60 psi setting shouldn't I have 71 psi on the
guage? No.

Re the low pressure in the shower: Not tank related I don't think.
Sounds like you have a blockage in pipes or the fixtures. I suspect a
partially clogged shower head. Not unusual for debris to be dislodged
when working on a water system. Usually the debris will clog an
aerator nozzle or shower head if not both.

Pre-charge can only be set with the pump off and the tank empty to get
it right. Then set for 2 psi below cut-in. You are probably right
that you are trying pressurize the entire plumbing system. It might
help if you have a whole house shut off valve in the system, probably
on the tank outlet, shut that before pressurizing. The pipes from the
tank to the pump SHOULD be full of water so no shut off is needed. I
say "should" because wierd conditions do exist.
