    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.
