i need to replace Cast iron pipe?
I’ve read most of the aswers to this similar question. I have some experience with plumbing just need a little guidence on this one. The problem is there is about a 2 ft ***** in the underside of my waste line. It’s about 8ft away from where it exits the house.I know it can be quick fixed but I want to replace it with pvc. My dad had redone our bathroom years b4 and replaced it with pvc. from that point to were the ***** is less than 16ft, thats bends and such. That part is the easy part. I know hiring a plumber is expensive, specially if it’s somethin i can do myself. I have the tools just need the guidence. My dad past several years so Me and my family help with a lot of repairs in the house. I Learn quick and Have done more than My share of tough jobs so im not worried bout the work just need more info on how to do it. thanks to anyone who understand this jumble (It’s been a long day.)
also is using a snap cutter or soil cutter better than any of the other tools recommended. hacksaw ect….. Is it safer too.

go from cast iron to plastic with a furnco coupling. its the rubber coupling with ring tight bands. works great for non pressure pipe.then use 3 or 4 inch p v c you will find 4 inch is cheaper if you can fit it in space you have to work. use drain fittings again cheaper than pressure rated fittings
A snap cutter is probably the best to cut the cast with. However there is a hacksaw blade that will cut it and be more reasonable for the number of times you will need it. You can either cut the cracked section of cast out and just replace with new pipe. to make the new connections use no hub couplers.
Without seeing it, sounds easy. You just need a hacksaw, PVC pipe of the same diameter and two couplings to connect the PVC to the old iron pipe. Cut the pipe with an (18 tooth blade) hacksaw Cut the PVC pretty close to the damaged iron pipe section, put the couplings on the PVC, slide the PVC pipe in, and slide the couplings over the old pipe and PVC, and tighten them down. Turn the water off and don’t let anyone use the sink, toilet, etc while you are doing this for obvious reasons.
Not knowing the full particulars, the best advice I can give is to measure the OD (outside dimemsion) of the pipes concerned, you can do this with a piece of string, just wrap it around the outside of the pipe you wish to measure, then measure the length of string with a tape measure, you could even take a picture of the pipes and take the info to your local plumbing supplier and explain the situation to them, they will be able to assist you, Best of luck
They make a rubber boot with band clamps on it that slips over the cast and plastic pipe. You’ll need a snap cutter for the cast iron pipe, you can rent them, just ask around.
you can join the two together with a rubber coupling, it is the only way to join PVC to any kind of metal,as for cutting cast i would use a carbide or diamond ,wheel cutter a hack saw is also good. you need to go easy cutting cast it can shatter if you get to over zealous,best bet is to go to a plumbing supply house and ask them they will be glade to steer you in the right direction .it,s their business
I suggest using a sawzall with a metal cutting blade. Since you state there is a ***** already, using a snap cutter may shatter the pipe. Of course, replace the cast iron with the same size PVC pipe. As mentioned prior, use a Furnco coupling to join the PVC and cast iron. The hardest part will be cutting away the old cast iron, from there it will be a lot easier. Good luck and I hope this helps.
Easy three stage job if it were out in the open… *L*
wack
run
glue n screw
* Wack off the old cast iron pipe well downstream of the end of the split so you don’t have to do this job again – splits do travel!
A sawzall w/a fine tooth metal cutting ‘bi-met’ blade
or a ’soil cutter’ snap tool
will make easy work of the required cut.
A square cut is wonderful but it doesn’t have to be perfect.
* Run new PVC pipe (same size as the old PVC pipe prolly either DVW or S40 pressure pipe)
connecting the two old pipe runs together.
* Glue n ***** as required.
So you’re still wondering about the screwing?
The clamps on your new Fernco clamp
connecting the new PVC to the old CI pipe of course!
The clamp’s ’shield’ (SS sheet metal) helps support the piping…. but it’s not absolutely essential given adequate supports.
Oftentimes it’s easier to start by gluing the new to old PVC joint first,
finishing the new piping run at the old CI pipe.
Try sliding the clamp completely on the pipe w/the smaller diameter
before gluing that last piece in place.
It’s easier to slide the clamp back in place
than
trying to squeeze the clamp between the two pieces of pipe…..
