2. Melt the lead in the ladle
3. Reuse the lead from the old joint if there is enough of it.

Pouring a Lead Joint

I don't plan on pouring any lead, going with some kind of rubber seal. I've been trying to do some more reading to figure this out. Maybe a closet flange repair kit would work in this case?

I also may need to raise the floor height higher than it was previously. So I've been reading there are extenders I could use over the current flange? I'm still not sure how those are suppose to attach to my current cast iron flange though.

The twist and set from oatey looks promising, but I'm going to have to go to the store to make sure it'll fit in my pipe. It may be too long as my pipe runs horizontally out, and curves up a very short distance.

Ok I bought the cast iron replacement flange and it seems to fit ok. I didn't remove the old flange though, I'm still trying to figure out the heights to see if I need to. I need to raise the height of my floor anyway, to create a stable subfloor around these tricky areas of pipe.

If I remove the old flange, I'll build up the plywood, then tile, and secure the new flange into the plywood and have it sitting flush with the tile. As long as it's secured to the floor, and the rubber seal fills any gap in the pipe, I should be golden right?

I may be able to keep the old flange in, and just treat it as part of the pipe. As long as there's a layer in between the old and new flange, and it's secure I should be good.

Hopefully I'm not missing something here. Since my rough-in is 10.5", I'm looking to get the AS Cadet 3 10" rough in toilet. The reviews seem favorable here. I was originally going to get the only 10" rough available locally at HD, a Pegasus Cottage...which don't have favorable reviews.

flange

What kind of flange did you buy? If it fits over the outside of the pipe, there is no way you can leave the old flange on it, and if it goes inside you had better make sure it is fairly smooth so the rubber gasket will seal to it. Personally, I do not use the internal expansion ones.

The flange should be installed on top of the FINISHED floor, and anchored through it. If you have enough room to get a decent piece of ply over the floor and the old flange and everything is nice and flat AND you can clean enough crud off the inside of the pipe so you can achieve a good seal, then you should be able to use the internal one.

It would be best if you leaded in a new one.

If molten lead is not your cup of tea, try one of these compression type flanges:
