Optimal Distance Between Toilet Drain Pipe and Wall: A Comprehensive Guide

In daily life, it is common to encounter situations where a toilet cannot be installed after purchase. So, what is the appropriate distance for the toilet drain pipe from the wall? What should be noted during toilet installation? Let’s take a look！

一、Appropriate Distance for Toilet Drain Pipe from Wall

Typically, the toilet drain pipe should be about 30-40 centimeters from the wall, but this depends on the actual situation of the bathroom and the method of toilet drainage. For bottom drainage, the distance from the drain hole to the wall is usually 30.5 or 40 centimeters. For rear drainage, the distance is approximately 20 centimeters. Additionally, it is best to choose a drain pipe diameter of 100 millimeters to prevent clogging, and the area around the drain pipe should be sealed with silicone or cement to prevent leakage.

二、Things to Note during Toilet Installation

1、Before installing the toilet, ensure that the floor is level. If it is not level, it must be leveled out in a timely manner, as this will affect the stability of the toilet. Additionally, any protruding drain pipes should be cut down. Once the floor leveling is complete, the toilet installation can proceed.

2、When installing the toilet, mark the positions of the sewage pipe and the drain pipe. After determining the installation position, use a power drill to make holes and install expansion screws. Then, place the sealing ring on the sewage opening. Don’t forget to apply adhesive to the sewage pipe to prevent potential water leakage later on.

3、During the installation of the toilet, make sure that the sewage pipe and drain pipe are aligned. Only when they are aligned can the toilet be placed. Apply silicone sealant to the bottom of the toilet to ensure it is secured. After that, install other components and check the tightness of the parts. If there are any issues, adjustments are necessary.

4、After the toilet is installed, fill the toilet tank with water and check for leaks. Also, check the flexibility and sealing of the inlet valve and outlet valve to see if there are any issues with jamming during use. Furthermore, pay attention to the effectiveness of the toilet’s drainage, such as flushing power, etc.
