?cleaning pipe?

Does anyone know the best way to clean a 4" cast iron pipe well enough to be able to attach couplings for a new piece of pvc. The cast iron is very rusty and there is some cement on it.

I would just knock the cement off with a chisel and use a wire brush for the rust. Then connect the PVC with a rubber coupling.

that could work or you may need a grinder to clean it.

unless it is a shielded rubber coupling (no-hub) most codes do not allow them above ground

The hammer and chisel, may not be the best idea.
On many older cast iron pipes, they are very brittle.

On the iron pipe,if you start it breaking or cracking, it may not stop, and you could end up breaking it off until you chase the cracks back to a place that makes it very hard to fix.

Just use a scraper to get all the lose flakes off, and use the rubber coupling to attach the pvc to the iron.
