The primary function of the pitless adapter is to provide a junction for the drop pipe in the well to connect to the water line running to the house. Not only does this greatly reduce the chances of surface water contamination through the top of the well, it provides an easy point of entry for well maintenance. The pitless adapter is used to connect submersible well pump discharge pipe to the horizontal pipe entering the house. The adapter includes two pieces that slide together to create a water-tight seal, allowing the pump to be removed from the well for service without digging the horizontal run of pipe.
Typical sizing for the pitless adapter is generally placing in a 5” – 12” diameter casing and with either a 1” or 1 ¼” drop pipe. Other sizes available upon request.
