flange in concrete too low

Just took out a toilet expecting to replace a cracked flange and discovered that it is set one inch below the concrete floor level! The flange is intact but obviously a seal is not being maintained. How do I fix this without having to break up the concrete floor. Is putting on two wax rings o.k. ? If I put some sort of extension on how do I attatch it so the pipes don't take all the weight?
Thanks for help!!

I have heard of extensions but have never used them myself.
The right way to raise any flange is to raise the entire flange. I have heard of using two wax rings. I have heard of sucess and problems so i always put it back the way if was intended.

Good Luck

two wax rings will be fine. Just be dead on when you set that toilet down. If you move the toilet up and down and left and right as you try to get it onto the bolts then you may mash the wax rings out of alignment and bust the seal. I use two rings with the plasic horn, You can place one inside the other and it helps to create a channel to divert obstructing wax and keep water down the center.

just my opinion but I have set thousands of these without incident. If you need more than two wax rings.....then I would say raise the flange.
