Trying to help a family member with limited financial means. They’ve been having to replace their well pump every 1-2yrs due to failure. It’s a submersible pump. I’ve advised them to get an independent water test and stop drinking the water until then. Also advised to get help from a professional. BUT. What is this? Is this calcium? How would someone treat their well to prevent this constant buildup and pump failure? Obviously in the home there’s going to need filters, probably neutralizer and softener. Plus whatever else.
