Yes. I have replaced a lot of old leaky cast iron sewer pipe and always use a sawzall. I use regular metal cutting blades. If you don't have the specific blade handy use bimetal cutting blades.
Use a Barbie head. Sawzall with metal cutting blade to cut through pipe without damaging cast iron pipe.
This takes a while, but should work. Use a hacksaw blade on the inside of the pipe and cut just through the pipe in two or three places depending on the size of the pipe. Once it is cut, you can pry the pieces out of the cast iron body.
Any good plumber knows a diamond blade is the best! ! You can use a Sawzall with "Grit Iron" blades, "Snap Cutters", or "Chain Cutters". Your cheapest way out of it would be either to rent a pair of snap or chain cutters, or buy the grit iron sawzall blades. Depending on how much cast iron your gonna cut, just be prepared to be there for a while if you are making more than 2 cuts through 3 or 4 inch pipe with the grit iron blades. Hi, Just cut a 4" cast iron pipe in less than a minute. I used a diamond blade on a Makita worm drive circular saw. Probably any circular would do as long as it has a little oomph Good Luck !!!! WayneRenovators & Builders Alliance, Inc.wvalzania@renovatorsandbuilders.com When confronted with having to remove a section of 4" diameter cast iron pipe, I initially considered using a hacksaw or grinder but the location was not the greatest(between floor joists under the upstairs bathroom). Save yourself hours of frustration by doing as I did and rent a chain cutter. It required very little clearance around the pipe and cut it perfectly in a few minutes and cost less than $30 cdn. MM SOMETIMES a hacksaw or Sabre saw with metal blades is even better than a snap cutter, as the snap cutter may crush a deteriorated pipe, and not cut it clean. However, with good quality cast, the snap cutters are still the best.
Yes, it is possible. Unfortunatly, if you have a cast iron riser, you will have to chip out the concrete to get low enough to cut the riser to install a Clamp-all and a piece of PVC pipe. This might not be possible if you have a short riser. Then you would have to cut the cast iron behind the 90 degree turn. Either way, it's a pain in the butt. Call a plumber. It will be worth it.
yes you can do it but you have to use a cast iron cutter, or cicular saw with a carbon friccion to cut arround the pipe. But if the cast iron pipe in in the ground and it's not muveble,, it may break.. so you have to be carefull and when you finish cutting it you put a piace of ABS pipe 1/2 shorter in each side. In order to incert the hob conectors..
Put a cutting blade on it and it shouldn't have water in it when you cut because of the possibility of shock.
You must break or cut the wall at that point. No other option
how do i cut cast iron
Cut out the old piping and caulk a new cast iron bell and spigot with lead and oakum and test
Cast Iron pipe can SOMETIMES be fixed by coupling it to the pipe using a rubber coupling and worm clamps. This rubber coupling is sometimes referred to as a "rubber boot". You should always check your local plumbing code first to see if what and where you are replacing can be remedied by this method. You would first need to cut the cast iron pipe section out which you want replaced. There are a few different devices and blades made to achieve this depending on what tools you have access to. The most basic can be found at your local home improvement center or plumbing supply house such as a reciprocating saw blade meant for cast iron. Once the section of pipe is out, you should be able to maneuver the boot or boots and pipe into place and tighten the clamps to fit snugly around the cast iron and PVC. The days of oakum and leading cast iron pipes is long gone :)
Yes, it should, I actually have a project that needs me to cut a cast iron pipe, and my soulution was to use a plasma cutter. The plasma cutter was develiped to cut both ferrous and non-ferrous materialls. Unlike a oxy-gas torch which is only good for steel which has a high Iron content, Plasma will cut steel, stainless steel (which has a much lower Iron content), Aluminum, and I am sure will cut other metals as well. The cutting action is based more on the extreme concentrated heat cutting the material more than a chemical reaction, or burning action of the material.
You just do it. Big help I know. There really isn't a question in your question. You cut the old pipe out and replace it. There is a chain cutter available that has a series of cutting wheels in a chain that you tighten down against the pipe and it basically breaks the cast iron pipe cleanly. Use a rubber coupler to connect the cast iron stub with the PVC. This is a short piece of rubber tube the right size to fit the pipe you are working with and is held on with 2 hose clamps. Where the cast goes into the floor or wall, you can take out the last section of cast and insert the PVC into the flare on the piece in the wall or floor and seal it as you would a piece of cast. Without a specific question, that's about all I can help you with.
