Cannot adjust cut-on on New SquareD Pumptrol switch
Users who are viewing this thread
The nut on the big spring adjusts both the cut-in and cut-out. 3.5 turns CCW lowers both about 10 PSI.
Usually you don't adjust the nut on the small spring, but you probably only turned the differential down to maybe 18 psi, from its initial 20 psi.
