In response to Re: Installing Toilet on Basement Rough-in
: When they built our 1986 home, they installed a rough-in for a toilet in our basement. I am planning on installing a toilet and have done plumbing projects but never specifically one like this.

: The rough-in for the waste pipe is black iron and sticks out of the concrete about 6 inches. We were not planning on putting any flooring down. I am assuming I need to cut the pipe off to install the toilet mounting flange.

: It the "chain-type" cast iron pipe cutter the best way of doing this (I would have to rent one), or is there a better alternative? I am assuming also that I have to cut it down to the floor level. Is that correct?

: Also, since the toilet will actually be resting on the floor, do I have to actually seat the flange so that the top of it is flush with the concrete floor (in other words break through the floor to seat the flange)? Or can I just set the bottom of the flange on the concrete? Or should I just mount plywood on top of the floor so that the flange is flush with it.

: Thanks of your help!

to set stool flush with floor cut pipe flush with floor. a small right angle grinder (like a mikita 4") with a thin (1/8") metal cutting disc will do nicely. you will have to drill holes for the toilet bolts and anchors, if caps aren't important you can use lag screws. put the wax ring right on the floor and bolt on the stool. if you insist on useing a flange, oatey makes one to fit inside iron pipe. you tighten 3 bolts inside the special flange, it expands in the dwv pipe and for added security a couple conserts finish the job. solutions are endless, go browse the plumbing dept at your local home depot or menard's and the light will come on
