I have a problem, trying to install a new toilet; when we removed the toilet we notice a iron flange (or pipe coming up in concrete) with a rim and no holes to put the new flange on. This item coming up through the floor remind you of a upside down top hat. How do we install bolts for the toilet if we have nowhere to bolt it. We are living in house built over 50 year ago. Any help will be greatly appreciated.

Thanks

How was the old one fastened down? Just time and a wax seal? Bolts that didn't seem to be screwed in? Sand or wire brush the top of the flange good. Look where the bolts should go, and see if you can see a couple circles of rust. If so, they are the top of old broken off bolts. You may be able to remove them. It will not be easy, see http://theoildrop.server101.com/ubb/...=000035#000000

If there is no sign of old bolts, you could drill and tap holes for the bolts.

Tom has more experience with these things, and may have a better idea.

We're going to hafta get together on terms.
"we notice a iron flange or pipe coming up in concrete."
A pipe is not a flange. It took me a while to decode "upside down top hat" but I finally figured out you were looking at a cast iron closet flange caulked on a 4" cast iron closet bend. ( I guess it would look like a upside down top hat at that.)
Are you saying there are no slots in the flange? If so there are inexpensive repair kits to fix the bolt hole situation. Is that your case? Labman touched on installing the toilet with bolts set in concrete. Let me take it a step futher. A closet flange isn't necessary to install a toilet. All a flange does is hold the bowl down securely to the floor. Wanna get yourself out of this with a minimum of hassle?
Set the bowl over the pipe where it will set. Mark the holes on the cement. Now remove the toilet and take a 14" masonry bit and drill down 1 1/4" inch on the marked holes. Tap in plastic screw inserts. Pick up a set of wood screw closet bolts and screw them into the plastic inserts. At the same time you pick up the closet bolts also pick up a wax ring with a funnel. Set the toilet,give it a little twist to seat the seal, tighten the bolts, connect the water supply and you're home free. Hey! Sound like a plan? Tom
