Question for those who know.

I am re tiling a bathroom floor that is concrete. I ripped up the old floor and upon removing the toilet, I found what is probably the original metal closet flange ( THE HOUSE IS 20 YO) which had just rotted away. It crumbled as I touched it. It would seem simple just install another flange but the PVC soil pipe has its own "flange" that the clloset flange was under. What Im trying to avoid is cutting the PVC to fit another closet flange in place. Any suggestions?

 

Hi, Just had the same problem. I sawed the abs flange off at the top. Patched the concrete with pour Stone. Bought a repair ring at the local home improvment store and set it in the correct cofiguration around the old pipe anchored it down with Tapcons. Set the new toilet with a thicker wax ring. Works great.

Thanks. I have to go out of town for work till thurs so Ill do this next weekend. Ill let you know how it goes. That was the solution I was thinking of, but was hoping to find something easy. Better just do it right. Thanks.

 

And I assume that you know to bolt the flange on top of the tile with only the thickness of the flange above finished tile floor level.
Good Luck!

 

Not to steal the thread, but I will be doing almost the same.

I am redoing the tile and the floor is completely torn out, I have already sawzalled the old xast iron off and will be coupling it with abs. But I do not know how high to screw the flange. I have installed the subfloor and I thought I could just screw it to the subfloor, but the tile and concrete board will raise the floor another 3/4in. Will this mean the seal will be too far and it will leak water? That's what a prfessional plumber did to my other house three years ago , he just screwed it to the subfloor and the tile guys just filed around it, I did not see him install the toilet, but I have not seen any wet spots from the crawl space eaither.

What is the rule for the flange does it need to be level with the floor (the subfloor or the tile)?

Any help would be great

 

A flange should be on top of the finished floor with only the thickness of the flange above the finished floor level.
It should be bolted to the floor. If its on tile, drill anchor holes through the tile. Use an awl or other sharp-pointed tool to strike a mark to keep the masonry drill bit from walking.
Good Luck!
