  • You should include a link to a source for a petcock to dispense from your 5 gal container, nearly impossible to use at home otherwise. It must match the 1" – 12 threaded hole in you plug cap and it should have a spout small enough to fit in spritzer bottle openings. Wouldn’t hurt if you included instructions to cut out the center of the threaded hole in the plug or even an extra plug with a hole. Here is a site for the right kind of spout .
