My home has a private well with a 3HP motor. The pressure switch is a 40/60 switch. Every time a faucet is turned on the pressure switch immediately turns on and remains running the entire time that the faucet is open. Is this normal? Also, I am wanting to install a lawn sprinkler system. In the past I have attempted to run 4-5 rain bird sprinklers but my water pressure drops to below 20 psi. This makes the water pressure in the house very low. How can I increase the water pressure to allow me to run a sprinkler system? Any suggestions would be greatly appreciated.

What size pressure tank do you have? Sounds like it's too small and requires the pump to operate anytime water is demanded. I'm installing a 220 gallon pre-pressurized tank on my new home well system to insure the pump does not have to operate every time. This tank allows about 85 gallons of water consumption before the pump is turned on. Also insures an emergency suppy in the event of electric failure (not unheard of in my area). Also provides a smoother supply of water.

The switch can easily be checked, by opening a faucet. Look at the gauge, and wait until the pressure drops. The pump should then come on activated by the low limit. Have a helper turn off the faucet, while you watch the pressure build back up. When the upper limit is reached, the pump should stop. If it does not, or if it cuts out at too high a pressure, then you have a problem condition. Obviously if the pressure gauge is broken, you can't perform this test.
