Hello. First time post. I have a Boshart 40-60 pressure switch on my water tank. Currently, the cut in is at 40 psi and the cut out is at 70 psi. I'm trying to adjust the differential to be more of 20 psi, however the hex nut on the shorter differential screw shaft is not compressing the spring at all. Continuing to loosen it does nothing to the cutoff pressure. Is it normal for the spring to be completely loose on the adjustment shaft?
Thanks.
Thanks.
