Seeking help on toilet flange extenders

[capitansquid]

Hi all, signed up to this forum as I've hit a snag in my bathroom reno and am hoping someone can kindly help with some advice.

Context: Replaced basement bathroom flooring from vinyl to tile. This resulted in raising the floor slightly.

Problem:
The toilet installation was a lead soil pipe to brass flange. Seems to be original to the house (early 90s) and the flange was in bad shape so I took the opportunity to take it out with the intent to replace it and install the new one properly over the new tile.
As the floor height is higher, I'll need an extender. My problem is that i've never dealt with, or worked with, lead pipes before and have no idea what I can and cannot do. Do you solder it? Pressure fit? Some sort of glue?
The local stores here carry both lead and pvc extenders and I'd like advice on which is better in this instance.
As you can see from the pictures the edge of the lead pipe is in horrible condition as it looks like it was not evenly cut (ragged and torn all over).

Can anyone chime in with suggestions on the best way and best product to install in such a situation?
First picture is the original, prior to removal. The second is the current situation.
Thanks

If you go to closet flange repair on-line there are different options you can use plus a couple video's. You can use the one I have a picture of as it goes into the pipe until the flange is flush with the floor and then there are three allen screws that you tighten. Make sure the lead is nice and round and if not you might have to take the lead out and put in new plastic pipe.

THanks for the quick reply.

I did look online for videos, but I've not found any that show what to do w/lead pipes.
Unfortunately pulling the pipe really isn't a good option as it would require tearing out the floor to do so. No crawl space or other access. NOT something I want to do.

The pipe seems perfectly ok once you pass the rim. Is that expansion flange ok to use on lead? It's pretty soft stuff so my ignorance makes me fear it being pushed outwards by the pressure of the mechanism. Is this a needless concern?

See if these work if you need to layer them put silicon in between View attachment Screenshot_20180319-140857.png

Ok, checked with Oakey (the manufacturer of those expanding closet flanges) and they do not recommend for use in lead piping as the metal is too soft. It will distort

Anyone have any videos on how to work with the lead extensions? Basically, one person told me all you need to do is jam the extension into the old pipe, hammer it in (friction fit I guess) then wrap it over the flange.
Anyone have any first hand experience on this that they could share?
Thanks

i think you should read the last part of tomfohio thread if that toilet ever gets clogged and you auger it you may put a hole in the lead.....a plubing supplt house mayhave an option also

I would get rid of the lead bend and go plastic. You would never have this problem again. It’s old technology, time to upgrade

 

[capitansquid]

Unfortunately, taking itout would be too costly. No access to the parts short of tearing out the floor.

Ah i didn’t notice it was a basement bathroom. No access underneath. Bummer

Sorry Captain, I have used them before, I just didn't over tighten the flange then I screwed the flange to the floor. Do you have about a 1/2" to 3/4" of lead sticking up above the floor. If you do you can get a lead repair flange and put it over the lead and then you hammer easily over the flange. Sorry, I thought you water some type of extender.

That quickset flange tomfohio mentioned is the best option if you don’t want to tear up the floor

Thanks. I did need an extender (don't have any extra lead sticking up). I actually got the lead AND the oatey twist n seal (similar concept as the one you recommended - they don't have that one here yet).
Ended up doing what you described using the "twist n seal". Just didn't feel comfortable working with the lead.
It's a snug fit and screwed it to the floor. Hoping it's tight enough and that Oatey is just being overly cautious by advising against it.
Thanks all!
