An annular pan for mounting over a drum lid containing a liquid, the drum top having a hole for a pump conduit and an air hole. The annular pan has multiple parallel elongated walls increasing in height from the pump conduit to a portion of the pan containing a drain hole axially aligned with the drum lid air hole. The drain hole is covered by a device having a slot into which a fine mesh filter can be inserted for catching debris in liquid. A raised edge of the pan above a top surface of the pan has an indentation for receipt of the pump conduit.
