Is It Necessary to Install a Backflow Valve in Your Toilet?

A toilet is an essential household item, and there are many details to pay attention to during installation. Is it necessary to install a toilet backflow valve? What should you pay attention to when installing a toilet? Let’s take a look!

一、Is it necessary to install a toilet backflow valve

It is not necessary to install one. The main function of a backflow valve is to prevent water from the toilet tank from flowing back into the water supply line. However, this situation rarely occurs in actual use. This is because the water supply line is under pressure, while the toilet tank is not, so the pressure difference does not cause backflow. Additionally, the water inlet of the toilet tank is located high enough that the water cannot flow back into the water supply line.

二、What to pay attention to when installing a toilet

1、First, when installing the toilet, check the alignment of the sewage pipe with the floor and inspect the pipe for any blockages such as mud or sand. You should also check if the installation position of the toilet is level with the surrounding area. If the floor is uneven, it should be leveled out before installation.

2、Before installing the toilet, determine the center of the sewage pipe and draw a centerline at that point. You can then secure the toilet in place; make sure the toilet's centerline aligns with the cross mark of the floor sewage outlet. Once leveled, firmly press the sealing ring and then install the anchor screws and decorative cap.

3、Next, install the sealing ring on the sewage outlet and evenly apply a layer of silicone around it. After that, you can install the water tank assembly. First, flush the pipe for 3-5 minutes to clear it, then install the angle valve and flexible hose, connecting them to the water tank and turning on the water supply.

4. Finally, once the toilet is installed, perform testing and inspection. Check if the inlet valve and seal are functioning properly, and ensure that the drainage valve operates smoothly without any obstruction or leakage. If your household water quality is hard and contains many impurities, it is advisable to install a filtration system at the inlet valve.
