I’m sure the previous owner thought he was being careful by wrapping the petcock barbs with tape, but duct tape? While on the subject, I know this is heresy amongst the DIY crowd, but how many uses does that crap really have? Even for its intended use, heating and cooling ducts, it sucks. Adhesive backed aluminum tape is far superior. It’s messy, sticks to itself but not that well to what you want it to. I’ve had the same roll for about 4 years and there’s still plenty left. I always find a better solution than duct tape. There I said it. Duct tape sucks. I feel better now.
