closet flange for cast iron pipe


I know this has been covered before but here's what i have. It seem's to be a 4'' pipe and it is very rough around the edge's. Also, another thing that kinda concern's me is the rust in the pipe. I have a crawl space but it's not very accessible because of the return for my heat/ac. I was looking into some flanges but wasn't sure if they would work with rust being in the pipe. Here's my question's:

1) Will the pvc twist n set or the cast iron type with the bolt's work in my situation and which is better?

2) Should i cut those edges so that they are flush with the flange i assume?

Will it work, or is it the best way to do it? The best way would be to get rid of all of that old cast and replace it with PVC. It's going to leak at some point.
Once you cut away the old lead with an ossilatiing tool a slip in flange will work but lub it first with vasalene.

The time to address this issue would have been before the tile was installed so that maybe it could have been worked on from above for the most part.

I agree 100% with you guys, i honestly don't remember it looking that rusty before but my camera flash sure shows otherwise! I really couldn't afford a plumber at the time. Now, i'm thinking i can switch it out with pvc from under the house if i have to.

1) How much of that 4 inch drain need's to go? I have no clue as to whether it runs to the road or what...guess i gotta investigate that.

Thank's guy's, any help is greatly appreciated! Merry Christmas!!

To bad the floor was not rotted out to. That way you could get to it by droping down through the floor.
Any and all of the old steel would be best if removed, including any steel supply lines.
PVC is cheap and easy to glue, but it would be best if you rented a tool made just for cutting it. If it indeed does run through the foundation wall it can be cut about 6" from the wall and reconnected with a cast to PVC hubless connector. Just tighten the hose clamps and it's done.

Off topic kinda...we paid a plumber to put in the drain for the washer and he connected the the main drain i guess... Tell me please if he hooked up hot water cause i'm only seeing a blue PEX line..

1) Is that worth 400.00 dollars of plumbing work in NC??

If you haven't fixed the toilet yet, I'd replace the pipe back to the PVC fitting. I'd also think about that galvanized branch too while you're down there. It will rust out on bottom someday.

I can't tell much on the PEX Colors don't mean a whole lot when all you have on your truck is blue. Blue, red, white, it's all the same.

I plan on taking the black pipe out all the way to the y adapter, i'm also goona replace some of the 1 1/2 drain that runs back to my sink. As for the pex line i'm not concerned about the color of pex but i do see that he tied in with white pex to my hot line.

Javiles: With all that wire there, i'm not sure if he had an option on it not being beside electical. Should it be moved?? Loose unsecure pipe where???
