: We saw some floor damage around the tolet so remove the tolet to see. We have to replace the section
: subfloor the tolet sits on. Looking up information on setting tolets they all talk about the flange and line
: up the tolet with the closet bolts. What is you do not have closet bolts to line up with? I have an old
: metal pipe. The bolts for the tolet went in to the floor. What is the best seal I should use with this type
: of pipe and what is the best way to set the tolet down? The link is a picture the old floor where the tolet
: sat.

I use a solid brass closet floor flange in situations like yours. If you have a "lead bend", you can pound the lead inward with a hammer, drop the flange over, and then pound the lead back over the flange. A few wood screws and you're done. An even tricker job, is to replace the "lead bend" with new plastic pipe and flange all the way into the cast iron fitting below the floor with a fernco bushing.
