The solution for both problems was a new “offset” toilet flange (available at home centers). Unlike a standard flange, which is centered on the waste pipe, an offset flange is off-center—that lets you shift the location of the toilet by a couple of inches (left, right, forward or back). As you can see, the offset toilet flange is primarily PVC, with a metal or PVC flange ring that circles the top that can be rotated to center the bolts as needed underneath the toilet.
A more practical and inexpensive solution may be to use an offset toilet flange to allow a standard toilet to be installed. Remove the old toilet , wax ring and flange if necessary. PVC DWV Offset Closet Flange Hub is used for non pressurized sanitary systems.
The sanitary drainage and vent piping are installed to remove waste water and water borne wastes from the plumbing fixtures and appliances as well as provide a circulation of air within the drainage piping. In this article we are going to review some different types of toilet flanges in order to determine what might best fit your needs and stay the necessity of replacement for as long as possible. An off-set toilet flange is different from a traditional toilet flange in that the top opening, which the wax ring and toilet sits above, is offset from the insertion point by varying amounts.
