Invented by a guy named MartinsonWe had a couple hose clamps let go on our submersible well pump one morning when we had a party scheduled for that afternoon at our house. The pump was running constantly, spraying out in the top of the well. A very good friend of mine that is a jack of all trades came to the rescue. We pulled the pump up about 6', removed the pitless adapter and replaced the hose clamps. If it weren't for my buddy Josh, the party would have had to be cancelled and who knows when I could have gotten a well guy out to fix it.
The name "pitless adapter" originates from the historical practice of using well pits to connect water wells to service lines. In the past, these pits required manual assembly and disassembly of pipe fittings, making maintenance difficult and unsanitary. The introduction of pitless adapters in the mid-1950s eliminated the need for well pits, allowing for a more sanitary and convenient connection between the well and the water line. This change was significant in improving well construction practices and reducing contamination risks.
