beerdog, whatever it would cost you it would be worth every penny!
I also learned from this. What I was wondering was how long has it been since the old melted lead pots were used?
Is cast iron more prevalant in Chicago than else where? I would think an iron/lead joint is going to last way way longer than a PVC/ABS joint. There was nothing wrong with mine after 38 yrs. The new toilet I bought did not have high enough clearance so I had to lower the flange a little.
I have replaced about 50 of these messed up things. I do it much easier and faster then this process.
1st - I take a hammer and just bust the old flange out as well as I can.
2nd - Use a chipping hammer with a flat bit and chisel the crap out of it until it is fairly flat and below the finish floor. "Believe it or not the flat bit chisels the old lead out nicely"
3rd - I use a standard steel or brass replacement ring. Set it in place mark hole positions with a pen.
4th - drill new holes in concrete with roto hammer.
5th - Use concrete anchors and new coated screws.
As long as you have the hammer it should only take you 30 mins to complete using this method and you do not need any packing and or lead.
we use poured joints on all my commercial jobs.
we still pour lead at closet collars and some floor drains/floor sinks
we still use hub and spigot cast on rough ins. I make a 20 lb lead hammer on each rough in
then melt it down on trim. have you ever used a 20 lb lead hammer to push cast?
its the bees knees!!!!
little tip on cast gaskets use e-z-tite by tyler. more easier to push
the 3 rib kind, the 2 ribs are a PITA
