Standard Installation Distance for Toilet Drain Pipes

When installing the toilet drain pipe, it is important to set it at an appropriate distance to ensure that it does not affect the overall effectiveness. Below, I'll introduce the installation distance of the toilet drain pipe.

What is the installation distance for the toilet drain pipe？

The reserved dimension for the drain pipe is approximately 75 to 90 centimeters, and it should be kept 30 to 40 centimeters away from the wall. For bottom drain toilets, the drain outlet should be less than the distance from the toilet to the wall. For rear drain toilets, the height of the drain outlet from the ground should be slightly higher than the height of the bathroom drain outlet.

What should be noted when installing the toilet drain pipe？

1、Choose good materials

When purchasing, it is essential to select high-quality materials. If the water pipe materials do not meet the requirements, the drain pipe may easily crack or get damaged during use. PVC pipes are a good choice as they are relatively durable and reasonably priced.

2、Install the pipe above, not on the ground

When installing the drain pipe, be sure to follow the proper sequence and ensure that the installation is done according to standards, including position and slope. It is recommended to install the drain pipe on the ceiling to facilitate future maintenance. Even if there is a water leak, it can be identified and resolved in a timely manner.

3、Add a cleanout to the drain pipe

During installation, a cleanout should be added, and the length of the drain pipe should be about 4 meters or more. Additionally, a flexible section should be included for easier maintenance in case of future drain pipe issues. If the toilet itself does not have a trap, an S-type trap can be installed during the drain pipe installation to prevent backflow.

In summary：the installation distance for the toilet drain pipe is approximately 75 to 90 centimeters, and it should be kept 30 to 40 centimeters away from the wall. I hope the above information is helpful to everyone.
