A pipe-support assembly 108 is configured to be positioned relative to the well casing 900, the pitless adapter 902 and the pump assembly 904.

Abstract: There is disclosed a connector which is sometimes referred to as a pitless unit in industry for use in a pumping system including a pump, well casing, a discharge pipe to guide liquid horizontally away from the pump, and a drop pipe to guide the liquid up from the pump towards the discharge pipe.
