Steve Often Wondered What It Was Like to Be a Fish

But then he realized he didn't like water. His fish, however, do. One problem: The pump for the well that supplies water to his home runs even when the pressure fails to build up, posing the risk of pumping the well dry. To guarantee a steady water supply, Steve designed a control device that shuts down the pump under extreme low pressure.
