Hey guys I've got a shallow well at one of my rental properties that has served me well for many, many years. However it was taking longer and longer to satisfy between cycles and had gotten to almost a minute so I did an acid wash of the well and now it cycles and fills up in about 15 seconds! The problem now is after the recent acid wash im getting small Amounts of sand... not a lot... but about a quarter cup every 4 to 5 days in my filter. Is it possible this will eventually go away or is there a bigger problem here?. A little info on the well....It is a shallow well, standing water is about 8 feet from the top. There is no foot valve,, only a check valve at the top and I have a 1HP sta-rite at the wellhead. Running a 30-50 switch. Any help or ideas would be greatly appreciated. Want to figure this out before it tears this pump up because it is fairly new as well.
