You readers have probably been saying, “Ol’ Schmitt must have a fixation with pitless adapters.”

I failed to mention in my last column that the pitless adapter along with the submersible pump and the captive air tank have, in my opinion, been the three great advances in pump system technology in the last 60 years.

As I wrote in my last column, the pitless adapter is a rather simple but important device used to complete a modern well. All of these have a way of keeping pumped water below the freezing point or frost line.
