2 Things to Know Before Shopping For a New Toilet Flange 2 Things to Know Before Shopping For a New Toilet Flange

Every so often the toilet flange, the collar that holds a toilet firmly to the ground, will break leaving the toilet wobbly and unstable. Before running out and buying a new flange, here are two things to know.

1 – Use Matching Materials

Determine if the drainage pipe that runs out from the bottom of the toilet is made out of cast iron or PVC pipe. While there are some glues that will bond a PVC flange to a cast iron pipe, in general, it is a good idea to buy a flange that is composed of the same material as the drainage pipe. The reason for this is that like materials bond well to each other. The better the bond there is between the pipe and the flange, the less likely it will be to crack, break, or leak.

2 – Find the Rough-In Measurement

The rough-in measurement is the distance from the back of the toilet to the center of the waste drainage hole. This measurement is usually about 12 inches (but is can be different), and will determine what type of flange will be needed. For instance, if the distance from the wall to the waste drainage pipe is the same as the toilet’s rough-In measurement, then the toilet can be installed with a regular straight flange. However, if the toilet’s rough-in measurement is larger than the distance from the wall to the drainage point, then the bottom of the toilet and the pipe will not line up. In this case, one needs to use an offset flange to bend the flow of waste coming from the toilet so that it will still be able to run down the pipe.
