Is It Necessary to Install a Toilet Check Valve

The toilet is a commonly used sanitary fixture in bathrooms, and many people install a toilet check valve to prevent backflow. So, is it necessary to install a toilet check valve? Let's take a look.

一、Is it necessary to install a toilet check valve?

It is not necessary to install a check valve. The purpose of a toilet check valve is to prevent backflow from the toilet, allowing water to flow from the toilet to the drainage pipe. However, in practical life, this issue rarely occurs. The water supply pipes have pressure, and the water pressure in the toilet also has pressure; there is a pressure difference between the two, so there is no need to worry about backflow. Additionally, the inlet of the toilet is positioned higher than the water level in the tank, which means that the water in the tank will generally not flow back into the drainage pipe. The stop valve is installed in the water pipe system, and it is advisable to use one controlled by water flow pressure. If the bathroom drainage pipe is a non-pressurized pipe, relying solely on water flow will not be sufficient to open the check valve, leading to potential blockages and ineffectiveness.

二、Maintenance after toilet installation

1、After installing the toilet, you should wait for the silicone sealant to cure before using it. The complete curing time is relatively long, usually around 24 hours. Some unprofessional workers, for the sake of convenience, may directly use mortar as an adhesive to fix the bottom of the toilet. However, since mortar has expansion properties, it can lead to cracking of the toilet base over time and complicate repairs.

2、After adjusting and installing the tank components, check for any leaks. Additionally, verify that the water inlet valve is functioning properly and that the flush valve moves freely without obstruction.

3、The flushing effect of the toilet is also very important. After installing the tank components, fill it with water. If the water flows rapidly and creates a strong whirlpool, it indicates that the drainage is clear. If there is no strong flow, check for any potential blockages.
