Toilet Flange too long

[Yakman]

Hey All.

I have a basic question about installation of a toilet flange..... I'm remodeling a bathroom and I had a plumber remove all the old ductile iron plumbing and replace it with new SCHD. 40 PVC. Everything was done except the installation of the new toilet flange which had to wait until I got the finished flooring installed and I figured I could do myself.

The plumber left a 3" toilet flange behind where the flange fits over the PVC pipe. There is also an unglued stub pipe extending from the elbow below the sub-floor to a point above the finished floor of the bathroom.

The problem I have is that the elbow below the sub-floor is installed so that the top of elbow is just below the bottom of the sub-floor. The depth of the supplied toilet flange is greater than the distance from the top of the elbow to the top of the finished floor. If I install the provided flange, the bottom of the flange will meet the top of the elbow before fully seating on the bottom of the finished floor. (See attached)

Can I just Cut the flange to the proper depth or do they make a shallow depth flange for this purpose? How should I resolve this?

Thanks in advance.
Yak

Yes but I would want a min of 11/4 on the collar left so if it’s 2” collar you can cut 3/4 off it etc
