Reply To: closet flange elevation

ARMDIVER,your questions are kind of confusing.The bottom of the closet collar ring should be flush with the finished floor. Are you using a floor drain with an incorporated trap or one similiar to a shower drain,where a trap has to be installed under it?The length of the pipe would depend on how low in the floor you want to set the drain.If you have a pipe sticking through the cement slab ,Iwould say you are up the creek
