HELP! We purchased a new (old) home (built in 1978) and had the water pump replaced on our well 2 days ago. When we got home, we ran the water in all of the sinks/tubs to clear the air and dirt/silt... most of them ran dry!! Well, 2 days later, we still have dirt in the water and now have NO cold water coming out in our shower. Any advice on how to get the cold water back AND how to clear the water will be appreciated. Thanks!
