I just joined this site. I do a lot of DYI projects. Even if it cost more than having someone else do it. It seems to always takes a lot longer to complete. Nothing is more rewarding than doing it your self. Question, I had a 4' deep well installed. I had a well with a above the ground pump that was here when I brought the house a year ago. The well was appox: 125 ft deep. what I could get from it was clear good tasting water. The new 4" well is apox" 90 ft deep. It is the worse water anyone could get. It smells, and has put iron rust color everywhere. Great pressure and using it at this time for lawn sprinkler system. I think if the well was deeper maybe it would be better water,but no way to know. Can I drill the same well deeper? I looked into filter etc. but the cost can get way up there. Any ideas? Thanks, Farmer Tom stuck in the city.
