I'm installing a Bathroom. I want to move the toilet. What should I use to cut the cast iron drain ( 4" ) going into wall? I want to use PVC drain for toilet, sink and shower.

Rent a chain break. It's a long handle with what looks like a chain with cutter wheels in it. You wrap the chain around the pipe and hook it back to the handle. You tighten the chain by twisting the handle and rotate it back and forth to score the pipe. You again tighten the chain and rotate it back and forth. Eventually the pressure breaks the pipe along the score lines. Nice tool.

One more idea... Another option as the chain cutter can also crush cast iron pipe if real old... use a sawzall with an 8/10 teeth per inch bi metal sawzall blade and just cut the pipe.. takes maybe 10 minutes if standard weight cast iron... 20 minutes if extra heavy cast iron pipe.

They also make a carbide tipped sawzall blade for cast iron cutting. From experience.. this is twice the price.. but does not reduce cutting time... just my opinion.

Either option works... and I usually use the chain cutter mentioned by HKstroud... but since this is first cast iron cut... I would stay safe and use sawzall.

Gets ugly if pipe crushes or cracks lengthwise!

Let us know what you go with and how it worked.. please. It is so important to follow through in answers as others read this thread and make decisions based on YOUR answers PK.
