Over a decade ago I installed a BruCo Closet flange extension kit to raise the flange due to a tile installation. The bathroom has been used very little and we are putting it back in regular service with a new Toto Drake II toilet.
The original kit was installed with the first flange sealed to the subfloor and the subsequent flange installed without sealant per the instructions. Since the first flange is in excellent condition I decided to buy another kit to replace the second flange which was coated in wax.
I checked with the manufacturer and was told that plumbers have been sealing the second or third flanges with sealant even though it is not required. The manufacture also recommended that I use three flanges, which will bring the stacked flanges about a quarter inch above the floor.
Should I stack the flanges so they are one quarter inch above the floor or keep the stacked flanges flush with the floor? The flanges have lips and are supposed to be self-sealing. I could use the supplied sealant for good measure. The attached photo shows two flanges installed that are flush with the tile surface.
Thank you.
