The plumbing aisle guy swore by duct tape for a weeping pipe joint, it lasted 3 days then sprayed everywhere
Some guy in the orange apron at the hardware store said just wrap duct tape around that leaking elbow and call it fixed, but by Tuesday morning my basement ceiling was dripping like a cheap faucet, so has anyone actually had tape hold a pressurized line for more than a week?
That "lasted 3 days then sprayed everywhere" part got me because I did the same dumb thing with a garden hose splitter last summer. Wrapped it in like half a roll of the gray stuff, felt like a genius for about a day and a half. Then I came out one morning and my whole side yard was a swamp and the wife was standing there with her arms crossed. Tape works great when there's no real pressure behind it, it's just a bandage for something calm. The second water is actively pushing at a joint, that tape turns into a wet noodle and gives up. For a pressurized line you need to actually fix the joint, not dress it up.
