New Pump - Low Pressure

I had a new pitiless well pump installed yesterday, the old 3/4 pump from 1991 was replaced with a 3/4 Goulds pump. With the new pump, at rest the tank pressure gauge is reading 40 psi, with water running 55 psi. Unfortunately, Iím not sure how much pressure I had with the old pump. Pressure is significantly reduced in every sink in the house. Screens were removed from the faucets when flushing the sediment in the lines.

Any thoughts? Is there a rule of thumb for pressure from a 3/4 pump?

Thanks!

Rest at 40psi and running at 55psi

Do you know when the pump is running ? Usually you can hear the water lines hum or vibrate. You can also hear the pressure switch close at low pressure and open at high pressure. You need to determine at what pressure the pumps turns on and a what pressure it shuts off at.

Bypassing the water softener solved the issue. Going to try a manual back-flush. But, itís a 12 yr old plastic Whirlpool that may need to be replaced.
