I've got a little job where a cast iron vent pipe clipped to an external wall in a driveway has been fractured at some time. The break is about 1 1/2" up from the concrete drive which it passes through. The break is neat and looks as if two pipes have simply been butted together, end to end. A cement collar had been made up, which has now broken up, to conceal the break.
Is there a repair coupling available to fix this? I'd rather not haul the whole vent pipe down....
Any help much appreciated!
If you have enough on the tail, then you could fit a collar of copper or ? around it, than wrap before covering with paint.

I'm sorry I don't have direct experience of your issue.
I just wanted to mention that, if you choose a different metal then Stainless is preferred, because of bi-metal corrosion - Al or Cu with iron will rust the iron quickly - a coupling/extension/cover of some sort would be ideal - if painted it should resist UV sunlight too (if relevant of course).
Very good point sir, never thought of things like that.
I meant to say:
A **PLASTIC** coupling/extension/cover will be ideal!
Sorry.

Yes - you need a 112mm dia Timesaver Coupling, for example Saint-Gobain Pipelines GT01. This is a cast iron collar in two sections which saddle round the old pipe and bolt together. Look at:

There are thick rubber sleeves with jubilee clips for joining soil/vent pipe - like
