What is the Typical Diameter of a Toilet Waste Outlet?

When we purchase and install a toilet, we not only need to pay attention to the distance of the toilet's discharge, but also the diameter of the toilet's drainage outlet. So, what is the typical diameter of a toilet's drainage outlet?

一、What is the typical diameter of a toilet's drainage outlet?

Generally, it is 80 mm. Under normal circumstances, the diameter of a toilet's drainage outlet is 80 mm, while the diameter of the drainage pipe is 110 mm. However, the diameter of the toilet's drainage outlet is not fixed and usually depends on the specific specifications, models, and drainage methods of the toilet. When determining the diameter of the toilet's drainage outlet, it is best to arrange it according to the actual size of your bathroom and usage requirements.

When installing the toilet, it is essential to ensure that the drainage outlet is tightly connected to the drainage pipe. If the connection is not made correctly or securely, it may lead to sewage overflow at the connection point, affecting the cleanliness and air quality of the bathroom.

二、What aspects should be considered when installing a toilet?

1、During the installation of the toilet, a sealing flange should be installed at the toilet's outlet, and the flange should be compressed to ensure a tight and secure connection between the toilet's drainage outlet and the drainage pipe, preventing any foul odors from coming back.

2、After properly installing the toilet, it is necessary to apply a ring of silicone sealant at the junction between the bottom of the toilet and the floor. This ensures that the toilet is firmly fixed to the ground, preventing any movement of the toilet and its internal flange interface, which could lead to odors escaping from the base.

3、After the silicone sealant at the bottom of the toilet has dried, a drainage test should be performed on the toilet to ensure that it drains properly and that there will be no leaks or blockages during future use.
