Hello everyone. It's been a while since I hung out. But here I am. Ok, so my wife and I are remodeling our bathroom. The cast iron waste line was rotted at the spot were the toilet flange pipe connects to the waste line. So I figured I was going to replace the cast iron with pvc. So I rented a soil pipe cutter. I first installed three pipe clamps to support the cast iron that wasn't being replaced. I then started to remove the cast iron all the way to the basement where I was going to tie in the pvc. Well when I was done , I noticed the pipe was loose. So I tried to pull up on the pipe and it all came up from the ground. Rotted at the bottom. Can I use a no hub coupling to connect the pvc to iron? Also, do I now have to break up basement floor to connect pvc to iron and if so, how do I locate which way the pipe is running so I can cut cement. Or what does anyone recommend?

Yes, you use Fernco "PVC to Cast Iron" shielded coupling. As far as locating the pipe goes: call plumber with pipe locator. He will trace the pipe for you and mark its location on the floor for you.

Can I use a no hub coupling to connect the pvc to iron?
Hey Dave, Welcome back! Yes, As Milo stated you'll transition to PVc from cast iron using a Shielded band, (see image).

I don't know why you would have to call in outside help to locate the pipe when you already have a starting place. I would start at the place the pulled up and follow the pipe until I found cast iron that was good enough connect to. If you find the old cast iron's too ate up to work with I would consider looking into a reline job. If you want more information on relining old cast iron I can help since I had it done at my place. Good luck on your remodel. Tom
