Customer Questions & Answers

Does this go under or on top of the flange?

Asked by: Elvis
It goes on top of the flange. I always backed out the existing screws and used them on the extension. You may add a small bead of silicon between extension ring and flange. I'm a flooring installer and I have used these hundreds of times with no leaks.

Screw holes do not match with flange that I have now. Drill new holes in old flange to match new flange or new holes in new flange????

Asked by: MJWJR
Turn the extender 1 notch so that the bolts go through a hole instead of the slot. Then the screw holes should line up. I'd rotate it so you're screwing into the holes and not the slot.

I'm putting down hardwood floors and the new elevation will be around 3/4-1" taller than existing floor. Stacking these doesn't seem (4 of them) practical or resistant to leaking. Is there a another product that would be better for my situation?
Asked by: Guitarpub
Obviously the best solution would be to remove the existing closet flange and install a new one at proper height, but that's only practical if you have access to the pipes under the flange. On concrete floors its not very practical. You CAN stack these extension rings. I always recommend to run a bead of silicone between the rings for a good seal, whether it's just 1 or a few rings. We've never encountered an issue with this method. . Also, since you're installing hardwood in a wet area (bathroom) I recommend you seal the edges of the hardwood where you cut it around the flange and run silicone around the cutout between the sub-floor and hardwood planks. If the bathroom is on an upper floor r a lower floor with wood subfloor I also recommend drilling a couple "drain holes" around the perimeter of the flange. In the even the wax ring is compromised and there is a leak around the flange, you'd rather have the water leak down below where all you have to do is repair some water damaged drywall than have the water seep under your nice hardwood and start to rot it away, which is expensive and time consuming to replace. Same with along your tub and shower skirts. Make sure that edge is sealed well so water doesn't get in there and start to rot/warp your nice floors.

Stacking Flange

I installed a new porcelain (1/4 inch) floor with a 1/4 in. concrete underlayment. When I re-seated the toilet, I used an extra thick wax ring. The toilet started leaking an so I'm considering using the stacking flanges. Should I use one or two flanges or consider another option?
Asked by: John
Sounds like you'll need at least 2 extension rings. You want the "flange" to be even with the floor or even a little proud of it, but not below the floor height. Even though it's not instructed to do so, I've always put a bead of plumbers putty or silicone sealant between the rings. Helps hold them stable and provides a better seal. Also make sure to use a wax ring with the plastic "flange" that extends down into the drain to help divert the waste past the extension rings. Hope this helps

Customer Reviews

1/4 in. Flange Extension Ring is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Flange extension ring Cost effective, perfect fit, installation could not be easier. After installing a new tile floor in a small bathroom, the height of toilet flange needed to be raised up abt 3/4 of a inch. These are stackable (I used 3) and none of the local plumbing supply houses had anything close to this item- theirs had to be drilled and cut to retro fit to the flange, while the Home Depot version had all the screw holes and Johnny bolt cut outs exactly where I needed them.
