How do you adjust an automatic water pump pressure controller?
If you want the water pump to turn OFF (cut out or cut-off) at a higher water pressure, turn this nut clockwise or "tighter". Adjusting the pressure on this spring shifts just the pump cut-out pressure up (clockwise) or down (counter-clockwise).
What should my pressure switch be set at?
For a single level home or a two story home without water fixtures on the 2nd floor a 30/50 PSI setting may be sufficient. For two or more levels with water fixtures on more than one level you may want to use 40/60 PSI setting. It's easier for a pump to supply the lower pressures and it's less strain on old plumbing.12 Feb 2018
