I have a large pipe running across the ceiling of my garage. I believe it to be a drain pipe. About 6 months ago I noticed a very small leak. It wasn't constant, but instead an unsteady dripping. I noticed the pipe was discolored and showing signs of rust. A plumper suggest Plumbing Epoxy as a fix versus replacing the whole pipe. I epoxied the two areas that had small drippings.
Yesterday I saw that the larger spot was shiny. A light gloss of water had seeped through the epoxy, not out of the sides, but straight in the middle of the epoxy.
I've attached pictures. What is your suggest? Should I sand off the old epoxy and place new on? Should I get a repair pipe clamp for the area? Cut the area that's rusted/weak and attach a no-hub coupling PVC pipe to the old pipe? It obviously needs replacing. I'd like the strongest yet cheapest DIY option. Thank you so much in advance!
