ABSTRACT:
A cap-to-casing adapter (166) is provided for use with a well having a well casing (12) with a top (28), having a support plate (136) that engages the top (28) of the well casing (12), and having a well cap (138) that encloses both a top portion (142) of the well casing (12) and a top portion (144) of an electrical conduit (146). In use, the cap-to-casing adapter (166) is inserted between the top (28) of the well casing (12) and the support plate (136). The cap-to-casing adapter (166) provides insect-proof protection for the well, secures the electrical conduit (146) to the well, provides for locking the well cap (138) to the adapter (166) with a padlock (188), and provides a standardized inside diameter (198) for sealing the well without regard to variations in the inside diameter (200) of the well casing (12).
