I know we discuss it here very often.. but now I need a refresher.. Working on a well system for a submersible pump. Had a bad gauge on it and was at times not wanting to cut off at high pressure...
I replaced the gauge, and cut in / out switch. and pre loaded air charge in bladder tank.. per tank instructions ie: "with no pressure or water in bottom of tank, air pressure in bladder should be 2 lbs less than cut in pressure of switch" The switch is in at 40, cut out at 60..
Shouldn't this switch /relay be closed when it's sitting on the shelf.. it being less than 40 psi?
I want to think I've got a bad switch.. it's a Lowes made in china.. Won't be going back there (the old home place) till Sunday.. Any ideas are appreciated..
