I had to replace my shallow well pump. It was a craftsman 1/2 hp 20/40. I replaced it with a craftsman 3/4 hp 40/60 pump. My problem is if you turn a hose on full blast the water surges. I also keep getting spurting in the sinks in the house. What I'm wondering about is the down pipe. I replaced it too along with the pump. The problem is that the casing in the ground is only 2" the down pipe I had to use for the pump is 1 1/4" I had to grind the lines off of the foot valve and couplings to get it to go into the pipe. At the time I installed it the we had been going through a little bit of a drought here in Fl. my water level was at 14' and I made the down pipe 20'. Since then we have had plenty of rain but the pump still does the same thing. I'm just wondering if the casing is to small for the pump and the pump is sucking the casing dry and that's why its surging. It's like the pump is sucking the casing dry then it fills up and thwe pump then suck it dry again over and over. If this is so should I replace the casing with a bigger one that sounds like alot of work or could I just drive a 11/4" drive point next to the casing an use it. Thanks for any help anyone may have on this.
