I'm remodeling my bathroom and in the process of leveling the old floor I'm raising the floor 3 inches. I need to extend the old cast iron flange up that much, what's the easiest way to go about this? I bought a PVC replacement flange that adapts to cast iron and seals with a rubber gasket but I think I will only be able to raise it about 2 inches.

Good morning Travis,

Before I can help I need a little more information. What size is the cast iron closet bend? 3"? 4"?
Would it be possible to break out the old flange and replace it with a deep throat cast Iron flange? I can most likely locate you a closet flange that will work but first I have to know what size I'm replacing. Regards, Tom

It's a 4 inch pie and there's no bend the flange is directly on top of the stack.

I want to see somebody sitting on your throne since the stack goes through the roof. It oughta be quite a sight. But seriously folks! Take my word for it there's a bend down there somewhere. My question still stands, Would it be possible to break out the old flange and replace it with a deep throat cast Iron flange? Cheers, Tom

You know I thought this was a good forum to answer my question but boy was I wrong! I thought this forum had professional advise. I'm a Journeyman carpenter and have seen a lot of plumbing put in and seen stacks that go through the roof for the vent and ones that have a bend in them just below the toilet flange and then go up. :mad:

Travis, Wassa matta Bro? No sense of humor?
You can knock us all you want but underneath your toilet is a horizontal branch leading to a bend that turns upright to a flange that the toilet connects to.
You said, "I'm a Journeyman carpenter and have seen alot of plumbing put in and seen stacks that go through the roof for the vent and ones that have a bend in them just below the toilet flange and then go up"

Let me give you the definition of a stack under "Definitions" in Chapter Three of the Standand Plumbing Code.
Stack-- A stack is the vertical main of a system of soil, waste, or vent piping and a "stack vent" is the extension of a soil or waste stack above the highest horizontal drain connected to the stack.
A stack is not a horizontal pipe and a toilet does not set on one. Case closed.
Now if you're through trashing us can we get back to your problem?
My question still stands, Would it be possible to break out the old flange and replace it with a deep throat cast Iron flange? They make a 4"cast iron flange with a 6" deep throat that can be leaded in to the closet stub up.
That would be my first choice, but then I broke in on cast iron and lead and oakum joints. The second choice would be to locate a flange with a 6" throat and a "O" ring that fits inside the 4" stub up. This flange would have to be secured to the floor but for a home owner probably would be the easiest to install since you wouldn't have to remove the old flange and pour and caulk a lead and oakum joint.

As for-- "You know I thought this was a good forum to answer my question but boy was I wrong! I thought this forum had professional advise."

We stand on our record. Out of all of the hundreds of people we have helped for free yours is the very first that complained about the service that we provide. You complaint was mean spirited and based on faulty knowledge on your part. Plus a noticeable lack of a sense of humor. But we still tried to answer your question as best we could. You have a great week end. Tom

I hang out on a number of sites, and haven't seen the quality of advice Tom gives elsewhere or even on other subjects. He maybe the best there is on the net.
