submersible pump: misbehaving pressure switch and pressure gauge

I have a submersible pump in a domestic well and use a Square-D 40-60 pressure switch.

I drained the tank and then installed a new switch and gauge but could not get the switch to cut in at 40psi and cut off at 60psi. It was more like 49/60. The water system turns on much more frequently than in the past and runs for a shorter time. I'm afraid of blowing out the pump with too many cut ins.

I replaced the switch and gauge with new ones again, and got roughly the same readings. I fiddled around with it and could not get the cut-in below 49psi.

So, I've installed 2 new pressure switches and 2 gauges and have a problem.

I'd read somewhere that I could lower the cut-in to about 30psi while having the cut-off still be 60psi. I can't get the system to 40/60, much less 30/60.

Any help in at least making a proper 40/60 setting would be fine. Setting it to 30/40 would be really fine.

Looking forward to receiving a response.

So how did you adjust the tank pressure? We have a sticky here that explains how to set up a tank properly, both the new style tanks that have diaphragms and the style that don't.

What pressure range switch did you buy? They come in different ranges. 40/60 psi is the highest I've seen commonly available on store shelves though they do make higher pressure range ones.
