      I want to replace my main in my house.It’s the old black cast iron and I want to use pvc.A few questions ahead of time.My toilet sits on top of the main and runs straight down about 6ft to the drain under the basement floor.A hub sits about a foot above the floor and is in good shape. I want to move the toilet over 1 inch or 2.If I do this will I have the flexability to line up and match the pvc from the toilet into the rubber coupling.Is it best to use the rubber coupling and connect the new pvc to the old cast iron or break out the old cast iron and run the main{new pvc} into the old cast iron hub.I’m not sure how hard this is to do or how to cut or break the old pipe.I have done a lot ov pvc plumbing and my dad says that we can do this. I would appreciate any help/details you could give me.Thanksrt.

      First of all it sounds like you have no vent on the toilet, be sure to vent the plbg. when you change over to PVC. Send me drawing of your fix layout and if it is 1 story or 2 story, if your toilet is sitting right on pipe and no other pipes running off then you are not vented. awp35@jcn.net
      Take a sawsall and get blade that cuts castiron and it will cut easy 12″ blade, and use a nohub band to reconnect. Like I say main thing is vent.
