 Crack in PVC toilet flange - how to fix?
Author: Zai (MD)

Hello all,

I found this forum while trying to google about my problem so please lend me your expertise! I tried to search on here for a similar problem but didn't see anything exactly like it so I apologize in advance if I'm duplicating any posts.

Anyway, I'm redoing the floor to an upstairs bathroom and after taking off the toilet and cleaning the flange (there was so much dirty wax on it), I saw that it had a crack. Here is a picture of it:



What is the best way to fix this? Can I buy a new flange and just put it on top of this one? I plan on doing tiles for the floor so it will be raised a bit anyways. I saw this HydroSeat Toilet Flange Repair at [www.homedepot.com] ...would this be something good to use?

Any comments and suggestions are much appreciated!! Thank you! thumbs

I'd remove that flange and install a new one. They don't cost that much. Any repair you try using this flange will take time and cost something for the needed patch/glue material, and it may crack again.

Yes I agree, replace it but it appears that the one you are replacing had the screw tightened too much which cracked the flange. Be careful when tightening the new one.

that repair flange may just work.. i looks pretty clever to me..
i would wipe some bowl wax on the old flange before pressing the repair flange into place.
remove the screws from the old flange to see if it will lift up about 1/4 inch to make up for adding tile..
use stainless screws to secure the new flange.
lastly, i would lather up those toilet bolts with a good grade grease. they are common steel and will rust but greasing them will make them live longer. also make sure the nuts are stainless. if not, toss them and get some.

Thank you for your replies, everyone. I was hoping to not have to replace the flange since I'm worried I might not cause it to leak elsewhere. I think I will go check out the options at the store and pick up a new flange if none of the repair options look viable.

Thanks again!

If I could jump in here about that repair flange.

I can understand plastic and better stainless steel. But I thought it would be a bad idea to use just a steel repair flange. Even if painted like the one mentioned.

I know cast iron can last but that is much thicker steel than that repair flange.
