I am building a new house and had the “rough-in” plumbing completed by a licensed plumber with the plan to complete most of the “top-out” work myself. The toilet drain lines, which extend about 8″ above the concrete floor, appear to be four inch thin-walled lead pipe?. What type of flange do I need to make the connection to this type of material? I can do everything else without any difficulty and hate to call the plumber to drive a long way for just this task.
Thanks for any help or recommendations as to where to find some written instructions.

I'm no plumber, but usually thin walled pipe is not used for toilet drains.
Either way, you can cut it flush with the floor and use an internal cemented fitting or an internal ribbed rubber oring fitting - or - chip out the cement around the drain pipe and use an external cemented fitting.

He probably used cast iron under the slab and you have a lead bend coming out of the slab. A brass flange is made that fits around the lead pipe which is screwed to the finished floor. The lead is then cut about ¾" above the flange and carefully flanaired out over the brass flange with a hammer- done.
You can also just forget about the flange completly, just cut the lead about an 1½" higher than the finished floor , flair it over , and set the johnie bolts into the floor with lead anchors.
Thanks for the help. The drain line in the slab was PVC, so I am not sure why or how we got to a lead pipe. Anyway, I will look for the brass flange and see if I can finish it as you described.
