Water

For several weeks I've been having well problems. Several months ago we started getting alot of debris in our water. About a month ago we had a whole house filter put on the well. In doing so, the mechanic showed me where the pump was going out. The debris was part of the impeller from the pump. I had a new pump put in. Now we are getting air in the water line somewhere. I've had two different people look at the problem and they can't see where the air is coming from unless it is at the source of the water. Thats down about 85 feet. They say I might need to go down deeper with the well. I'm not sure just what to do yet. Both places say they don't know if that will fix it or not but they don't know what else to do. The joy of home ownership. I'm getting ready for a walk now. Take care and have a wonderful day
