My home was built in 1957, is on a slab and the drains appear to be cast iron. Upon a bathroom renovation, the closet flange was broken. There are no significant lips to do a repair. Question, with the drain being cast iron, and the drain pipe extending high above the "final" floor, it does not appear that I can replace the closet flange as I do not have a place to securely anchor the flange to the floor. Is a tourque flange/ring called for here? Is this a job for a real professional?

Remove the old flange and install a expansion flange, (see ikmage). Check them out at; Toilet Flanges from the most FAMOUS Internet PLUMBING SUPPLY
This is a easy job and can be done by the home owner. Good luck and thank you for rating my answer. Tom

Hi Tom

I went to a store you are probably familiar with (Gorman's) and obtained a similar closet flange as you illustrated above. Mine does not have the gasket - is it imperative to have the gasket? As it appears to work (very homeowner friendly once I got the excess crud out of it), the flange fits in quite easily and have the tourque screws inside to tighten as an expansion joint (of sorts). The instructions did not indicate if I needed to put any type of sealant etc. is it necessary?

The torque screw version is but the ones I have used do have a gasket type collar. Can you post a picture of what you bought or give us the model#/brand?

Hi Ballengerb, the product number is 43539 4 CI RPLC PVC CLST FLANG manufacturer is Oatey Casper's.

Many thanks in advance for your input as well!

You are good to go with that Oatey. That black collar is your gasket, it swells when you tighten the screws.

Super! Like I posted earlier, it does not look like the one that Speedball1 posted the image of - I just want to make sure before I do any more work that will be permanent.

Do I need to "add" any sealant, caulking or anything else for that matter?

Both flanges in question work just fine. You do not need any sealant but I usually grease them with plumbers grease if they are tight.

A note on that. Do Not grease the neoprene gasket with any type of lubricant that has petroleum in it. Such as Vaseline. It will rot the neoprene. Good luck, Tom

Tom is right. Plumbers grease or silicone gel are acceptable but automotive grease or Vaseline are not good.
