Water Well Casing Extension

Extending a 6" steel water well casing using an arc welder. Before the invention of a fitting called a "Pitless Adaptor", wells in areas that have freezing weather had the "well head" left several feet below grade to protect the water line from freezing. There was no standard to the construction of the well pit or how the water line for the well pump was to be installed. Commonly pits were made with galvanized coverts with concrete lids, concrete block or just buried out right. The problem with having a well head in a pit is that is susceptible to surface water entering the well with bacteria and other contaminates. Locating and servicing the well is more difficult in a pit. When a well head sticks out of the ground (12"-18" is a good hight) it is much easier to service and much less likely to be influenced by surface water. In most municipalities today a pitless adaptor is required to meet local building code.
