Toilet Flange Size
Posted by Rod Hooper on May 27, 2002 at 23:21:17:
Does the toilet flange size, 3" or 4", make a difference? I have a 4" flange on a second story toilet that uses a 4" to 3" elbow into a 3" drain pipe. I would like to use a 3" flange with a 3" elbow to gain space. I removed a drop ceiling in my kitchen, and of course it turns out that the drain pipe extends about .5" below the rafter at the lowest end. The 3" elbow would let me maintain the correct slope and still fit. Any thoughts? Thanks.
