What I like best, is when the floor is rotted, & the carpenter or handy hack removes the toilet themselves, & replaces the flooring, & cuts the new wood around the outside edge of flange. This is especially nice on a 2nd floor.
Or those new construction plumbers that cut their holes with a skill saw. Try screwing that flange down,....... to maybe the insulation below.

As a combination of [years back] new work & service we have hit this closet flange item pretty often. Last new house I did was in 2006. We always left the closet flange loose. That way the tile man could pull it and get his tile under the flange. Now some times there was a new employee and his boss did not tell him that the flange was loose, he would tile around the flange also his wonder board or wet mud was around the flange. The 1/2" sub floor doed not allow much screw holding power in any event. Also when there is a void under the flange the wax can be pushed through the bolt slots thereby taking out the seal. Our fix on the wax pushing through was we always set on rubber -- no wax. As to not being able to find solid wood or no wood we would take 1/4 all thread rod
cadium plated heat it and bend a right angle bend leaving the leg long enough to get back under the wood. We then mounted the flange and
nutted down the rods we made. Then cut the rod off flush on top of the nuts. Worked half decent when the job required it. Never had a problem with the nuts on top of the flange. Just like a wolverine double nut pak of bolts.

I rough in with a 3x4 closet ell and use an inside 4" flange. I never install the flange until the FINISHED floor is installed. I've never worked in a home that had a 1/2" subfloor....... Some love to install the flange before the finished floor is installed.......FAIL

I always set the flange before the floor coverings went down.

I would put a flange spacer under the closet flange to get the proper height and screw it down through the spacer.

I do the exact same thing, but very few do, simply cuz it takes more time.
No-one, & I mean no-one, can anticipate the exact height of finish floor.
Example....... oh my wife seen some marble she liked better than the ceramic tile we originally were going to get. Or we are running short on funds so we decided to go with linoleum, ect....... And most never consider what heigth the flange was roughed in at.


However, did you know that gluing a flange inside a 4" pvc pipe is not code? I had this conversation with the chief of plumbing division, in mich, who gave us a code update class. The reason......... because the inside of the pipe is not approved or rated, only the outside of the pipe is, therefore you cannot glue anything to the inside. He said if you have 4" stubbed up, you must use a flange that fits on the outside of pipe.
Now I agree it's BS, & inspector will most likely never catch it anyway, cuz the flange will be installed, at same time as toilet, on the finish, (and I might add, at the perfect height).

hmmmm.... i use slab flanges all the time very interesting...and that guy your talkin about is a idiot JMO....

ranman

i had the same code up date class. on the ring being glued in the pipe.

i was thought the same thing.

He is the chief of our state plumbing division, be careful, he could revoke your license. He also said he wants to have tankless water heaters banned, because of flow restrictions. They want restricters on faucets, & then want to ban tankless, cuz of restricted flow? Definitely must be a government run agency.
