Have had a new Grundfos SQE pump installed. The existing pressure tank is still in use. It is 60 gallons. CU301 is set to 60. Installer said he calibrated the tank. Anyone know what that meant? Don't recall him changing the pressure in the tank.
Looking for info as I'd like to use the lower PSI settings to save electricity when the power is out and I am powering it with a generator.
Thanks!
