Frequently Asked Questions
After the toilet has been removed, you must remove the existing toilet bolts and clean all the old wax off the existing toilet flange. Decide how much height is needed in order for the bottom of the top flange to be parallel with the finished floor height. You should replace the existing flange if it is broken or rusted badly; the spacer kit will not work for this application. After confirming the existing flange is in good condition, install the new extra-long toilet bolts into the flange. You can use the gaskets that come with the kit to seal between multiple PVC spacers, but 100% silicone is recommended between the top of the existing flange and the bottom of the first spacer. This will ensure that all voided areas are water tight between the transition points. After the desired height is reached, the flat washers and 1/4" nuts are threaded onto the extra-long bolts. This will compress and hold the spacers in place. It is recommended that you try and secure the new spacer or spacers to the subfloor through the four holes molded into the spacers. You can now install a wax seal and finish the toilet installation. Never use one of the seals in place of the wax seal. THE TOILET WILL LEAK WHEN FLUSHED!
Is there a flange that can be used to replace a broken or corroded cast iron flange for a toilet?
Oatey offers three styles of repair flanges for this application.
The first is the No-Caulk cast iron repair flange which comes in two depths. Once the old flange is removed and cast iron pipe is cleaned off, these flanges will slide over the vertical cast iron drain pipe. The flat side of the gasket should be facing down and resting on the inside bottom lip of the flange. Tightening the four bolts in even rotation will compress the gasket against the outside of the pipe, and create a water tight seal. Remember that the bottom of the flange must be set on top of the finished flooring, and then screwed into the subfloor.
The second is our PVC or ABS Twist-N-Set repair flange which inserts into the vertical cast iron drain pipe after the old flange is removed. The gasket tightens as the flange is turned in a clockwise rotation. Remember that the bottom of the flange must be set on top of the finished flooring, and then screwed into the subfloor.
The third option is the PVC or ABS Replacement closet repair flange which also inserts into the vertical cast iron drain pipe after the old flange is removed. This flange is sealed by the tightening of three stainless steel bolts in even rotation. This compresses the gasket between the outside of the flange tail piece, and the inside of the cast iron drain. Remember that the bottom of the flange must be set on top of the finished flooring, and then screwed into the subfloor.
All flanges must be screwed into the subfloor before setting the toilet bowl into place, this sometimes will require drilling pilot holes through the finished flooring.
Do the flanges create a water tight seal around the pipe and hole that the pipe passes through?
No. The flanges are strictly cosmetic. If the penetration in the finished surface needs to be watertight, you will need to use an approved silicone product for application.
What metals are the metal flanges made from?
C1008 Sheet Steel
Does Dearborn Brass/Oatey offer different styles of Flanges (escutcheons)?
Yes. We have 6 different styles of flanges that are listed below. All flanges are designed to cover the oversized hole opened in a finished surface in order to allow a pipe to pass through it without restriction or contact with the finished surface. This difference in size allows for expansion and contraction. All the styles of flanges are finished with a chrome plating.
Metal - Low and High Pattern Flanges are normally used when a water line is passing through a finished surface horizontally or vertically. For example, wood cabinets, painted walls, or finished floors.
Metal - Box Flanges are normally used when a drain line is passing through a finished surface.
Metal - Floor and Ceiling Plates are normally used when pipes are passing through walls or floors and ceilings, this is common in commercial or multi-family building applications. These flanges are also available in a split version, which can be installed after the pipes are in place.
Plastic – Split Flange Plates are used in the same applications as the Low Pattern Flanges. The difference with the plastic flanges is that there is a small molded line through the flange, which can easily be snapped in two. This allows for the flange to be installed as the pipes are assembled, or onto pipes already assembled. If the pipe is already in place, the plastic flange can be snapped on the molded line and installed around the pipe. Both applications give a nice clean finished look.
Should I put plumbers putty or silicone under the shower drain flange?
100% silicone caulk is recommend. There are many conditions where plumbers putty could cause product failure and finished product staining, please refer to category #4 FAQs for these applications.
When would a Closet Flange Spacer Kit be used?
The Closet Flange Spacer Kit is used when the finished floor of your bathroom is higher than the bottom of the existing toilet flange.
Is there a replacement flange for a PVC or ABS toilet flanges when the existing metal flange has rusted away?
Yes. The Moss Bay Replacement flange is designed specifically for this application.
