Disclosed are integral and/or portable, easy-to-install apparatuses for detecting and containing fluid leaked or otherwise discharged from a fluid-filled device and for facilitating testing and maintenance of the apparatus and fluid-filled devices. In one aspect of the disclosed invention, upon sensing a fluid discharge, the apparatus activates audible and/or visual alarms and directs the discharged fluid to a predetermined drainage area to prevent damage to areas surrounding the fluid-filled device. In another aspect of the present invention, no plumbing or electrical wiring is required to install the apparatus, thereby allowing an unskilled individual to easily and inexpensively install the apparatus. In yet another aspect of the present invention, the apparatus may be easily located since it is not dependent on gravity or a drainage pipe for discharge of the fluid. Furthermore, the apparatus optionally includes an integral leveling mechanism to accommodate leveling of the apparatus when placed on uneven surfaces.
