Hi! I hope there is someone who can help us! If your well casing is damaged, will an anuular seal be the only way to fix the problem and can one expect that the seal will last the life of the well? Someone hit our well several months back and we have had sediment coming into our home ever since. Well actually the insurance company installed a filter, which is stopping it from coming into the house, however, the filter is filling up daily with junk. We want to make sure the problem is fixed, either by installing the seal, drilling a new well or hooking us up to town water. Any information would be helpful, as we are not sure what would be the best remedy. Thanks!
