Today I went to patch a water pipe under my front porch, that leads to a faucet in my front garden. The pipe had developed a pinhole leak over the winter even though I had done my best to shut off the water.
I had my trusty copper pipe cutter in hand, but after crawling under the porch, I quickly realize I was in over my head, because I was actually dealing with what I think is an iron pipe. (some orange / brown rust, and when I sanded a small spot it came up a dull silver color)
I had planned to just cut the pipe where the pinhole was, and use a Sharkbite compression fitting to splice the two ends back together. I have no idea how to do the job on an iron pipe (about 1/2" in diameter).
Also, the pipe appears to run under the entire width of my porch (about 6') without any support and is only supported by a wood latice on the end where the faucet attaches. I have serious doubts that the iron pipe will be strong enough to support its own weight over the 6' span if I splice it. Perhaps I could add some support strapping to it an tie this into the porch frame above?
Looking for some advice on a best approach here.
