Will a 75mm Toilet Pipe Get Clogged with Stool?

Toilet is one of the essential sanitary fixtures in a home; however, many people do not understand how to choose the size of the drainage pipe when installing a toilet. Will using a 75mm pipe for the toilet cause blockages? What should be noted during the installation of a toilet? Let's take a look！

Will using a 75mm pipe for the toilet cause blockages：

Generally, it should not cause blockages, but you need to be especially careful and avoid flushing sanitary paper or other items, as this may increase the likelihood of clogs. If possible, it's best to choose a 110mm waste pipe for easier use in the future.

Toilet blockages can be related not only to the size of the drainage pipe but also to the quality of the toilet itself. If the toilet does not use a full glaze process, the inner wall may be uneven, and over time, buildup can occur, leading to blockages. Additionally, incorrect installation, such as misalignment between the outlet and the drainage pipe, can also result in clogs.

Things to note when installing a toilet：

1. Before installing the toilet, thoroughly check the drainage pipe for any debris or sand, and make sure the position of the toilet is level front to back. If the floor is uneven, it needs to be leveled.

2. When installing the toilet, pay attention to ensuring that the drainage pipe and outlet are aligned properly. After positioning the toilet correctly, mark the bolt holes, then remove the toilet and drill holes at the marked locations. A hole diameter of about 20mm and a depth of 6mm is advisable. Then, insert 10mm bolts, apply putty, and place rubber washers.

3. Finally, when installing the water tank's outlet elbow, first remove the nuts from the water tank's outlet and inlet. Place them back-to-back onto the outlet elbow, inserting the upper end into the water tank and the lower end into the toilet inlet. Then place the rubber washer and tighten the nut. If connecting with a double elbow for the water supply, measure the dimensions of the float valve and the water supply pipe before installing the double elbow.
