pump never reaches shut-off pressure

I installed a new water tank with new pressure switch, gauge etc. The new switch is a 40 - 60, however the pressure never increases beyond 50 lbs. Should I lower the setting on the cut-off pressure to 50 lbs or is there another problem?

What type of pump do you have?
Even a jet pump will usually reach 60 psi, unless it's pretty worn out.

It's a Submersible pump. There seems to be plenty of water pressure in the house, it's just that the gauge never hits 60 psi.

A submersible pump should be able to hit 60 psi, unless it's not rated for the depth that it's set at, or it's worn out. You may need to adjust your pressure switch lower so that the pump will shut off.

I think the pump is about 20 years old. I will lower the cut-0ff pressure to 50 PSI and see if it comes off and on normally. I'm afraid that it's been running continuously the last 5 days, since I installed the new tank and switch. Thanks for the help.

If the pump is that old, it may be that there is excessive wear in the impellers/diffusers that is preventing it from building 60 psi.
