Cast Iron Drain Pipe: Should it stay or should it go?
Was sent your way via the JB forum. I'm redoing a shower and underlying plumbing issues have sent me here for advice from you guys.
The house: 1971 build in Miami, FL on slab on grade.
The issue. I have a 2" CI drain from a walk-in shower stall that was cracked. I have removed the riser pipe and p-trap that was cracked with the idea to replace with PVC fernco'd to the CI horizontal drain. Now I am looking at a cast iron horizontal pipe that I am debating whether to replace with PVC or not.
Below is what the pipe looks like after flushing out the gunk with a garden hose. Which by the way it swallowed up every drop without any back ups for several minutes. So flow is seemingly not an issue.
So the big question is, would you replace this pipe at the cost of busting up 5 lineal feet of concrete back to the toilet? I do plan on staying in this house long term, possibly for the rest of my life. But I'd love to not have to take on this type of repair at this point. What say you, fellas? Should it stay or should it go? Does it look that bad? It's been in the ground for over 40 years.
