I have a 4 inch well system with a well mate tank of about 40 gallons. My pressure switch is set at a low of 40 and a high of 60. I have pressure in the holding tank of 38 when the tank is empty. The only problem I see is the pump seems to cut off and on more than I would like to see it and only runs a very short time before it shuts off.

My real question for you experts is what would be the effect if I had a low pressure on the holding tank, say about 30 pounds, and what would be the effect if I had a high pressure on the holding tank, say at about 50 pounds?

Another question what would be the effect if an irrigation system consumed more gallons per minute in the 40 pound pressure range than the pump could put out? I can see that the pressure on the irrigation system would drop and therefore the outflow but would it reach a point to where the pump would ever cut off?

Thanks so much for your thoughts.
Bill
