Removing the old pipe First you want to make sure the section of pipe that will remain, is properly supported (you don't want it falling). Then you'll want to install some temporary supports, to catch the portion of the pipe that you'll be removing. Use a chain cutter, hammer and cold chisel, or grinder to break the pipe a few inches before the hub on the ...

You're going to have to cut out the pipe, and replace it with PVC drain pipe. You can get rubber connectors (fernco) for the transition. Here's a youtube how-to: http://www.youtube.com/watch?v=EFaJyIzyiYA

Why is it rotten? Does it bode ill for the rest of the system? I would replace as much cast as is easily doable with ABS. I would cut above and below where the K sink drain comes in and replace everything back to the sink with ABS. Is there a particularly good sawzall blade for this? Standard metal blade will do - I just cut a 4" myself no ...

For cutting the pipe, go rent a chain pipe cutter (aka soil pipe cutter). It will make short work of the pipe and not be too messy. It will make a clean enough edge that a Fernco coupling (like you have a picture of) will work fine. Obviously you will need to add some strapping to secure the horizontal run of iron pipe if you go this route because you ...

Cast Iron drain pipe with Bell fittings, these are packed with oakum and overlaid with hot poured lead driven in place to seal and then a second layer poured in to complete the seal. It may only need the lead driven in to repack the oakum and a new layer of lead poured. Contact a plumber with knowledge about old drain systems, cast iron can take a long ...

Moisture pooling in the joints like that suggests standing water in the pipe, which will eventually rust it out for sure. If this is the case, there's probably a blockage of some sort downstream that's resulting in sewage backup (ew). I would definitely address that first. After that, you can decide whether or not it's worth replacing pipe. My guess is that ...

DIY cutting cast iron is pretty easy, but it's a little counter-intuitive. Cast iron is extremely brittle compared to steel. That's important for how you approach it. Cutting it with a sawzall blade is going to be very slow and frustrating. I think the best choice of blade would be along the lines of the diamond-grit "friction" blades, but any sawzall ...

Remember, cast iron is brittle. A chain-breaker does not actually cut it, it cracks and separates it. You can use the same principle: use the angle grinder make a groove to weaken material around the perimeter of the material right where you want it to break. Then allow the grinding wheel to penetrate all the way through at only a single spot (a 1/4" or ...

I was poking around some to see what other were saying about this because I am having the same issue with my stove after replacing some of the rubber feet. Found something on Amazon that looks like it would work. Thought I would share. Red Devil Industrial Grade Heat Resistant Rtv Silicone Sealant Product Description Sold as each. 10.1 Oz. Cartridge. ...
