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).

Abstract: A plastic well assembly (10) includes a plastic well casing (12) with a hole (16) that is disposed therethrough transversely to a casing axis (14). An adapter plug assembly (38 or 268) is disposed inside the casing (12) and is forced toward the hole (16) by a plastic locking cam (58 or 272) that is a part of the adapter plug assembly (38 or 268). The locking cam (58 or 272) is retained by a pin (60 or 282) or by a cam follower-retainer (274) that serves both to transmit the force of the locking cam (272) to the well casing (12) and to retain the locking cam (272). The adapter plug assembly (38 or 268) is supported by a plastic support plate (26 or 136) that engages the top (28) of the casing (12), and a well cap (46 or 138) covers the support plate (26 or 136).

Abstract: A plastic well (10) includes a plastic well casing (12) with a hole (16) that is disposed transversely to a casing axis (14). A plastic adapter plug assembly (38) is disposed inside the casing (12) and is forced toward the transversely-disposed hole (16) in the casing (12) by a plastic locking cam (58) that is a part of the adapter plug assembly (38). The adapter plug assembly (38) is supported by a plastic support plate (26) that engages the top (28) of the casing (12), and by a plastic support tube (32) that is bonded to both the support plate (26) and the adapter plug assembly (38). A plastic saddle (18) is disposed outside the casing (12) and is bonded over the hole (16) in the casing (12).
