Repairing cast iron downpipe?

But Lobster's still alive and kicking though...

God was that three years ago? At the time I needed an instant solution to stop the damp, and just sleeved the cracked pipe with a small strip of heavy-duty (green!) polythene sheeting to stop the water getting to the house wall, with a view to sorting it out properly when the warmer, drier weather arrived. But guess what - I'm embarrassed to say that three summers later it's STILL there! One day I'll get round to it :(

One tip you might want to consider... we had an extension built on our house about 15 years ago, and were very keen to make the old and new match up. The builder ended up nicking some of the old cast-iron guttering from the back of the house (replacing it with similar-looking plastic stuff), and using it on the front of the house to extend the original guttering seamlessly on to the extension. Might be something worth considering if you have drainpipes round the back which are in better nick?

It was 1.5 years ago, Lobster has probably been eaten by now. Lots of places supply epoxy putty. Can't say I've had great results with it.

However there was a more recent thread about this from somebody else only about two months back. Brian

Yep, and I used two part filler (actually it was wood filler but the same as car body filler). Removed existing paint, drilled a hole to stop the crack progressing, applied filler, sanded down and spray painted using rattle cans. It stopped the leak.

What, to take the pipe back to when it wasn't corroded?
