When a pump comes on, it needs to run for at least 1 minute. When it goes off, it needs to stay off for at least 1 minute. These are minimum times as 2 minutes on or off is even better. Your tank must be water logged or out of air. Even a 10 gallon tank should give you 2 gallons of water before the pump restarts. It should not come on the instant you crack a faucet, and it should stay off longer than 5 seconds between cycles. Bladder tank or Hydro Tank? One pipe into the tank or two?
