Quick Tips for Measuring the Rough-In Distance of Your Aging Toilet

When installing a toilet, it's essential to pay attention to the toilet rough-in size. However, if the toilet has already been installed, how can you determine the rough-in distance? Here’s how to measure the rough-in distance for an old toilet.

How to Measure Rough-In Distance for an Old Toilet：

You can use a piece of cardboard and place it vertically next to the toilet’s drainage hole. Then, use a tape measure to measure the distance from the cardboard to the wall; this measurement will be the toilet's rough-in distance. Alternatively, you can measure the vertical distance from the center of the drainpipe to the wall; this distance will also represent the toilet's rough-in distance.

How to Prevent Toilet Clogs：

1、Installation

To prevent toilet clogs, it’s crucial to pay attention during installation. Many toilets frequently clog not because of quality issues but due to improper installation. For example, if the toilet outlet doesn’t align correctly with the drain or if the screw holes at the bottom of the toilet are not sealed, or if the water tank’s water level is too low, these issues can easily lead to clogs. Therefore, extra care should be taken during installation.

2、Usage

To minimize the risk of clogs during use, be especially mindful of what you flush down the toilet. Avoid disposing of items like bones, hair, and paper towels in the toilet, as these can easily lead to obstructions.

3、Quality

If the toilet itself is of poor quality, it can also lead to clogs. Toilets with rough or uneven glazing surfaces and uneven piping are more susceptible to blockages.

4、Pipe Diameter

If the toilet’s drainage pipe is too small and waste cannot flow smoothly, this can also cause clogs. Therefore, when installing a toilet, it's important to ensure the pipe size meets the standard requirements to minimize the chance of blockages.
