Since I moved in a year ago my well has produced a lot of sand. I've installed a sand trap between the pump and the pressure tank and two in line filters at my house. About a week ago the pump went out after about a day of pure sand. I had the well jetted for an entire day and a new pump put in. It seems though that the "solution" did not fix the problem as I was told it would? Any suggestions on what to do next?
