I have a shallow well for watering the lawn. I turn on the pump and a little water comes out of spigot. I close the spigot for a couple minutes and turn it on then air comes out. I let the pump run for about 10 minutes then it will pump water the rest of the day. I'll turn it off then the next day it takes another 15 minutes to start running again. What should I do or try to fix this problem.
