I am posting this for a friend, I don't know wells.
40 year old house, about a week ago water starts coming out brown. They have a plumber come in, he finds a crack in well pipe. He replaces it (says well is 75' deep). He tells them to turn power off to well pump and open up faucets until dry. Turn power back on and in a few days water should be good. A few days later, it isn't any different. Hot and cold are both bad. Pressure has been consistent.
What could be causing this? Any info would be a help! It's hard living without water.
