flange repair, is this what I need?


remodeling the bathroom in the basement and I'm not 100% certain if I'm looking at the correct part. The cast iron toilet flange is broken and nowhere close to level. I don't see any obvious joint where I can remove the flange from the pipe. My thought was to just cut the existing flange off as high as I could, maybe 1/2 in above the slab at most and then use something like this http://plumbing.hardwarestore.com/51...t--645944.aspx to replace it.

Is this a correct fix? Or is there a better way to do it? I'd like to avoid tearing up the slab If I can.

won't the flange be WAY too high if you do that? I would think so. I think you need to remove the entire old flange, even if it means breaking out some concrete around it to disconnect and remove the old flange entirely. the sleeve on the flange must fit tight to the existing pipe in my opinion.

How old is the house? Is this a cast iron drain or is it PVC? The flange must also be bolted to the slab, repour the slab and insert new studs when you repour the concrete slab. Not seeing it, that's my best guess.

NO THAT IS NOT THE CORRECT WAY ! !


YES THERE IS ! !

FIRST TO GET OLD FLANGE OFF TAKE A HEAVY 5/8" COLD CHISEL WITH A HEAVY HAMMER, USING CHISEL WITH THE HAMMER MAKE TWO CUTS
RIGHT WHERE THE TWO BOLT SLOTS ARE LEFT AND RIGHT THIS SHOULD
SPLIT THE FLANGE AT THAT POINT TAKE A SMALL SCREWDRIVER
WITH A MEDIUM SIZE HAMMER TO CLEAN OUT THE LEAD AND OAKUM
THEN THE TWO PIECES OF THE FLANGE SHOULD PULL UP OFF THE PIPE !

THEN GET ONE OF THESE INSTANT SET CLOSET FLANGES TO GO BACK IN
IT'S PLACE IF YOU HAVE TROUBLE CONTACT ME

The house is 39 years old, and yes it's cast iron pipe. No PVC.

The flange has to be bolted to the slab? I can tell you the existing one isn't. I'd guess tapcons would be the way to go for that?

So I can break the existing flange with a cold chisel? That I can do. To be honest, I didn't even consider attacking it like that since I figured it would just ad frustration to my life. I have 0 experience with cast iron. I considered trying to heat it but figured that there was no way I could get enough heat into it to melt the lead and work it back out.

I'm failing to understand how the instant set ring works. what does it grab onto? I've got to hold it to understand it I guess. It also appears to be missing the slots that the J bolts for the toilet go into, so I'm guessing there is something else that I need to go with it.

at any rate, thanks for the help.

THE I.S. FLANGE SLIDES DOWN OVER THE C.I. PIPE MAKE SURE IT IS ALIGNED

AND THEN TIGHTEN THE 3 BOLTS EVENLY, THAT LOCK'S IT ONTO THE SEWER PIPE

THEN PUT YOUR TAP CON SCREWS IN IF YOU WANT !

I NEVER ADDED ANY SCREWS WHEN WORKING ON A SLAB FLOOR

AND
YES IT HAS SLOT HOLES FOR THE CLOSET BOLTS !

Ok that makes sense now that I look at the pic of it again. I'm a little bit concerned about the height above the slab, so I guess I might need to break up the slab a little bit to recess it. I think once i have it in my hands I'll have a better idea. thanks again

I have had a similar issue and everything I read says that while there is some room to wiggle, the correct location is for the flange ring to be set on the finished floor.

That flange you are looking at is one that was recommended to me.

Good luck!
