Which type of closet flange extender?

[lardy1]

I'm seeing different types and the reviews aren't anything I trust so I turn to those I do trust. The GJ folks.

I had vinyl plank floor covering installed in my basement over existing concrete. The closet flange was set years ago and the concrete floor is actually a bit higher than the top of the flange. Add in the thickness of the vinyl and I have an inch at the maximum (about 1/4" variation in my difference. A heavy inch being my max). I know whatever I use should set slightly proud of the new floor.

Is there a preferred type? Watching youtube idiots and trying to decipher pictures and specs online get confusing and tiring. I just want it to be right. Any recommendations from those of you in the Know?

Thank you in advance.

I prefer using the type that extends down onto sewer line then twists to compress gasket but sounds like you can get away with just a flat shim. Use one of the wax rings with the rubber extension if you use standard shim.

That looks like it may glue inside of 3” pipe. Not ideal and limits your options for a quick fix. Id probably just try and get by with a deep seal flange but if it were in my house, I’d be tempted to cut it out, chip out around it and put a new flange glueing over the pipe with a SS ring on it. Those plastic rings ****.

If you can find something that’s compression inside a 3” pipe that might work but I don’t think they make that. It wouldn’t leave much of an inside diameter. I believe the horn on the bottom of the toilet is 2-1/2”

Just use this: https://www.homedepot.com/p/Korky-Wax-Free-Toilet-Seal-Kit-6000BM/205616926

If you need more height than is included with the one kit get a second one. You won't have any problems.

It's stamped 3x4 so it depends what size sewer line is there. Regardless it should glue over 3" or inside 4" pipe.

I didn’t notice the stamp, the width of the plastic is what made me think it was one that fits inside 3”. Yeah, if it’s glued into a 4” riser OP has lots of options. I’ve even glued a 3” coupling inside of 4” pipe to raise a flange.

I decided to go with the plastic spacers. I ordered two 1/2" and one 1/4" to stack and play with to get a suitable height. The height is about 1/4" variation so I'm thinking about even with the high spot and proud around 1/4 on the low. Lots of silicane between the spacers and I center punch the concrete so I can drill for stainless tapcons before assembly and clean everything back up. It should be stable. Here's hoping.

Thanks for the advice and ideas.
