I have been using a 1/2 hp mastercraft shallow well water pump for about 5 months. When I first got it, it took me a couple of days before I could finally get it to prime and bring the water into the house but when I did finally get it, it worked great. My water line coming into me trailer froze so I had to unplug my pump and steam out the line. I got it completley thawed and have been trying to prime the pump for days and it just wont catch. My well is 20ft deep and it is approximately 30 ft from the trailer. Do you think I need a bigger pump to be able to pull the water all that way? Or is somethin wrong with my pump or pressure tank? I don't know much about them.
