The Ultimate Guide to Measuring Your Toilet's Rough-In Distance

The installation of a flush toilet is very important. If not handled properly, it can affect its usage later. Now, let's take a look at how to measure the toilet rough-in.

How to Measure Toilet Rough-in

Before the toilet is installed, you can measure the distance from the wall to the drainage pipe, and then measure the diameter of the drainage pipe to calculate the radius. Adding these two measurements together gives you the rough-in distance. If the toilet has already been installed, you need to find the S-trap pipe on the side of the toilet and measure the distance from the water tank to the ground where it connects to the drainage pipe; this is the rough-in distance.

Maintenance After Toilet Installation

1、After the toilet installation is complete, do not use it immediately. You should wait until the cement and mortar have fully set, and the sealing silicone has cured. Note that if you choose a construction team that is not very professional, they might mistakenly use cement as an adhesive. While it can serve to seal, it can crack in a short period, making repairs complicated, so you must pay special attention.

2、Once the water tank is installed, check for any leaks. Turn on the tap water and let it run for about 5 minutes to clean the pipes. After that, install the angle valve and hose before connecting the water supply to check if the water fills properly and if the sealing is effective. Additionally, the installation position of the flushing valve should be flexible and free of obstructions.

3、Then, check the toilet's drainage performance to determine if it meets future usage needs. You can fill the water tank and try flushing the toilet. If a vortex occurs or the flushing speed is fast, it indicates that the drainage pipe is clear and not blocked.

In summary：this is what we have covered regarding how to measure the toilet rough-in and the maintenance needed after installation. Are you clear on these points? Accurate measurement of the rough-in distance is essential for the installation process to prevent unnecessary issues later on.
