Thread: Questions about closet bends/closet flange.

  1. #1

    Default Questions about closet bends/closet flange.

    I'm moving a 3-inch toilet rough-in. I have space limitations next to a floor truss. The 4X3 closet bend and flange I've looked at have an outside diameter (hub end of flange) of 5 inches. A 3" street 90 will work as far as elevation and the hub end of the flange has an outside diameter of 4 inches. I've read some of your forums and some posts mention a 3" closet bend. Is there a 3" closet bend or are you talking about a 90-degree street elbow? Any problems using the 90 street with a closet flange that has a female end that fits on the outside of the elbow (spigot end?). I know that a 4X3 bend is preferable but I'm tight for room.

    Another question--what are the pros and cons of an all abs closet flange vs. an abs flange with a metal ring other than being able to rotate the metal ring prior to mounting it to the floor?

    Thank you in advance.

    I would consider an all ABS closet flange to be the ultimate in junk and highly likely to break causing a loose leaking toilet and rotting out your floor.

    I would consider a ABS flange with a painted steel ring to be junk as it is highly likely to rust out causing your toilet to become loose and leaking causing your floor to rot out.

    I would install An ABS flange with a stainless steel ring and consider it to be the only acceptable method of doing the job.http://www.oatey.com/Plumber/Shared/...eel+Rings.html
