Hi, Thank you for this forum,
My toilet need a new closet flange. The drain pipe going to it is 4" OD galvanived colored pipe that is soldered on the outside apparently with lead to about 2" of black colored pipe (hopefully threaded) and the 2" of black colored pipe attaches to the cast iron elbow entering into the the cast iron stack.
The wax seal is good but the flange has seperated from the floor and whatever seal held the flange to the galvanized colored drain pipe is broken so the toilet rocks.
I don't want to replace the flange with one that needs oakum and melted lead. I want to use a flange like that Oakey 4x3 replacement flange that easily expands into the inside of 4" cast iron pipe (not Oakey's Twist-N-Fit, the other one). But Oakey seems only to make those in PVC and I'd like to know if someone makes a good one in cast iron?? I worry PVC isn't strong enough for a toilet that is just secured by the flange bolts only and not attached to the floor.
I don't know much about plumbing so I don't know if this is an unusual situation or totally completely normal and the above Oakey pvc replacement flange would be a no brainer. But as far as I'm able to assess, a cast iron expanding seal flange (or whatever they're called) would solve my problems, possibly in combination with a red ring thing, flange heigh extenders, etc., which I have a handle on.
Thank you very much four your time! After a bad flange job 2 years ago I'm ready to do it myself.
