ABSTRACT:
A wet seal standpipe cap to eliminate standpipe cap leakage includes a generally circular cap which has affixed to the underside of the cap a plurality of baffle rings. The cap is sized to enclose an opening in the top of a standpipe, and permit one of the baffle rings to penetrate a liquor contained in a canal placed around the standpipe opening providing a wet seal. The cap, in cooperation with the canal, entraps any leakage from around the standpipe opening between one of the baffle rings, underside of the cap and contained liquor.
