Frequently Asked Questions

The most frequently asked questions about the installation of our toilet flange repair kits.

Q – Can I find your kits at Home Depot or Lowe’s?

A – As of June, 1 2014 our kits are available at select Lowe’s…plus, Menards, Ace Hardware, Do It Best and regional plumbing supply houses. Please view our Supplier Map to check and see if your local home improvement store is on our list. If not, you can order directly from our online store

Q – What is the diameter of your spacers & extender and how do I remove any ceramic tile that is in the way?

A – The diameter of the spacers & extender flange is 7-1/4″. There are a couple of ways to remove the ceramic tile, you can use a cold chisel or a Dremel tool. To use a cold chisel, you should make sure the waste pipe in your existing flange has a rag stuffed into the hole or is covered, then chip small sections from the outside inward until you have enough room to fit our spacers.

Q – Should I use the type of wax ring with the ‘black plastic/rubber cone’ ?

A – We do not recommend them since when used they can leak. Using a standard wax ring is the best option since when using our kits you will be bringing the level of the toilet flange up to the perfect height. That is on top of your finished floor.

Q – How many spacers can I stack together?

A – For a new installation of a toilet flange you can use any height as long as you use longer screws. When using the extender flange we recommend no more that 2-1/4″ of our stackable spacers since theExtender’s waste line is 3″ in length.

Q – Is the extender smaller than my toilet’s waste line?

A – No…the inner diameter of the extender is 2-5/8″. Your toilet’s waste opening (on bottom of toilet itself), dependent on toilet manufacturer, is normally between 2″ to 2-1/2″.

Q – Will the methane gases from waste system be stopped completely by the rubber gasket?

A – Yes…the hole in the gasket fits very snugly to the extender to provide a water & gas-tight seal.

Q – Will this rubber gasket wear out over time allowing gases to leak in the future?

A – The gasket will outlast both us!!  It has been tested and approved by IAPMO, UPC and is NSF compliant. It is made of the latest material development by Durofoam.

Q – The flange extender inner diameter is ~2 5/8” vs. 3” for the existing flange opening. This is approximately a 15% reduction in cross-sectional area of the pipe. Will this contribute to clogs? What have been other’s experience who have used your product?

A – Actually, the ID (inner diameter) of the toilet outlet is usually anywhere from 2” to 2-1/2”. So there is no reduction in the flow from the toilet to the drain pipe, therefore it will not contribute to clogging of the sewer or toilet pipes. We have sold well over 30,000 of our extender kits without one single return or complaint. We have plumbers and plumbing inspectors that have installed them on their own homes. Since we are the only extender in the US that has been code-approved, we can only get that distinction by passing strict guidelines and testing.

Q – The kit package states that the gasket should be approximately 68 degrees Fahrenheit to insure proper sealing during installation. Not sure what the significance of this is, but just to insure that I install it correctly, we keep our house at about 60 degrees. Does this mean that prior to the installation, I want to get the temperature in the bathroom up to ~70 degrees until the installation is complete?

A – We put that on the bag to protect us from someone taking it out from a car that has been in the cold freezing temperature and trying to take it out and install it without it warming up to room temperature. You’ll be fine at 60 degrees. Otherwise…just use a microwave for about 10 seconds on High!! just like defrosting a frozen English Muffin…!

Notice how the 'horn' of the toilet fits inside the toilet flange. That is the correct height to be at.
