These well seals fit on top of the well casing in systems where the water supply line runs up and out of the casing and through a center hole in the well seal. They prevent surface liquids and debris from entering the well and contaminating the water supply. After installation they only need to be removed for well maintenance or well seal replacement.

These well caps fit on top of the water well casing in systems that use a pitless adapter, which is a device that is attached below ground to the well casing. The adapter provides a sanitary and frostproof seal between the casing and the waterline that runs out from the casing to a building. Well caps prevent surface liquids and debris from entering the well and contaminating the water supply. After the well cap is installed, it only needs to be removed for well maintenance or well cap replacement.
