Toilet flange question

I have a three inch waste line in my basement bathroom. The flange that was on that line was a four inch that fit over the outside of the drain pipe. I purchased a three inch flange to fit inside the waste pipe as there isn't a whole lot of room on the outside of the pipe to get a new four inch over the pipe.

Will the three inch that fits inside the pipe work well or should I go back to the four inch flange?

By the way, the flange I removed was leaking bad. The previous home owner did not have the flange installed far enough down on the outside of the pipe. There isn't a lot of space there so I thought maybe this internal pipe flange would do the trick.

Thoughts?

 

The three inch flange will work just fine. Be sure to orient it properly so the hold down bolts will be at the 3 and 9 oclock positions.

 

Yup, no problem with what you purchased.

They have 3/4" flanges that work on either pipe size. For 3" pipe, they go on the outside, 4" on the inside.

Also don't forget to screw/tapcon it to the floor. The pipe isn't meant to hold the toilet and flange in place, the screws into the subfloor are.
