Aspirin, also known as acetylsalicylic acid (ASA), is a salicylate medication, often used to treat pain, fever, and inflammation. Aspirin also has an antiplatelet effect by stopping the binding together of platelets and preventing a patch over damaged walls of blood vessels.
The device, which connects to the plumbing, regulates the home's water supply. When the water pressure drops to a certain level, the switch senses more water is needed, and spring-loaded electrical parts make contact, turning on the well pump. When the pressure returns to a preset level and the well tank is filled, the electrical contacts separate, and the well pump turns off.
Place the 7/16-inch wrench on the second nut and adjust it clockwise to increase the cutoff setting for the well pump. The second setting tells the pump to shut off after reaching the desired pressure level and the water pressure tank is full. Set the cover back on the switch, but don't tighten the acorn nut yet.
