Abstract: A device including a connecting piece implement, the connecting piece implement is configured to be operable for preventing jamming or malfunctioning of a toilet flushing mechanism, wherein the connecting piece implement enables a flush lever of the toilet flushing mechanism to open or close a flapper to allow or prevent water to flow from a water tank into a bowl of the toilet. The connecting piece implement comprises at least one flexible material that is configured to engage an attachment aperture of the flush lever and the chain coupled to the flapper. The flexible material having a first end portion and a second end portion. The connecting piece implement further comprises at least one locking element, the locking element including a first lock component disposed on the first end portion of the flexible material.

Abstract: The invention includes methods of inhibiting microbial growth in a well. A packing material containing a mixture of a first material and an antimicrobial agent is provided to at least partially fill a well bore. One or more access tubes are provided in an annular space around a casing within the well bore. The access tubes have a first terminal opening located at or above a ground surface and have a length that extends from the first terminal opening at least part of the depth of the well bore. The access tubes have a second terminal opening located within the well bore. An antimicrobial material is supplied into the well bore through the first terminal opening of the access tubes. The invention also includes well constructs.
