I have a deep well that works fine. It has a 5 ft well pit that is under my driveway and covered with a manhole cover. It also has not been any problem. I have recently heard about pitless adapters that eliminate the pit and reduce the possibility of contamination entering the well from the pit. But how does the adapter allow access to the pump if the connection to the lateral line that goes to the house is 5 feet down? Does it have some type of connector to the lateral line that disconnects when you pull up on it? Or do you have to dig up the whole thing to pull the pump?
