if you have a pump for the whole house you need to check the bladder tank. there is a air valve on the top. Check the pressure with a tire gauge you should have at least 20 PSI this will stop the pump from the on and off thing.

You can compress air yuo can not compress water. thats why the ballder tank. As the pump work to shut off pressure it is compressing air. then when you use a little water the pump does not run until a large about is run then the pump will re fill the system

Best of luck
