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 – Not yet but we are working on it…we are in contact with many big box chains who are working on evaluating the products they sell. Hopefully we will find a spot on their shelves very soon. Until that time you can order directly from our online store
**Update: We will be in selected Lowe’s – Home Improvement Warehouses beginning July 2012.

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.

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 you and I, 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 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 15,000 of the extender kits without one single return or complaint. We have plumbers and plumbing inspectors that have installed them on their own homes. You don’t get a plumbing product code approved without it passing strict guidelines and we are the only extender in the US that has been code approved.

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 a frozen English Muffin…!

 Here is a cross-sectional  view of how a toilet and flange are supposed
to be installed. Note how just one standard wax ring (without a rubber cone) will create your water & gas tight seal.
Using extra wax rings to ‘make up the difference’ with a toilet flange that is too low will lead to a leaking toilet…and ultimately damage to your sub-flooring!
