07/01/2025 | Hawkrown

The toilet is used frequently, and if you’re not careful, water leakage can easily occur at the edge underneath the toilet. Here’s how to address this issue.

What to Do When You Notice Water Leaking from Your Toilet Base:

1、First, use a utility knife to remove the silicone sealant at the contact point between the toilet base and the floor.

2、Next, lift the toilet and tilt it at a certain angle to check if the sealing ring on the toilet outlet is damaged or not secure. If there is a sealing issue, it is recommended to purchase a new toilet outlet sealing ring and place it on the toilet outlet.

3、Place the toilet straight and align it with the drainage pipe, then use silicone sealant to properly seal the base of the toilet.

How to Install a Toilet:

1、Check the Level of the Drainage Pipe

Before installing the toilet, check for any mud, sand, or debris blocking the pipe, and make sure the surrounding area is level. If the floor is uneven, it should be leveled before installation.

2、Determine the Drain Center

The toilet has a drain center. Before installation, determine the drain center by placing the toilet upside down and marking a cross centerline on the outlet, extending it to the bottom and around the feet of the toilet.

3、Secure the Toilet

It's time to secure the toilet. Align the toilet with the cross line on the drainage outlet, apply pressure to the sealing ring, and then install the floor screws and decorative caps.

4、Ensure Bottom Sealing

Install a sealing ring on the outlet, and apply a circle of silicone sealant around the area.

5、Install the Tank Components

Finally, install the tank components. Ensure that the water supply pipe is clean before proceeding. Use a shut-off valve and a connection hose to install, connecting the hose to the tank components and then turning on the water supply.

6、Testing and Inspection

To ensure successful installation, inspect the toilet. This includes checking if the water valve and seals are functioning properly, and ensuring the flush valve is positioned correctly without any blockage or leakage.

In conclusion:this article has provided information on how to address water leakage at the edge under the toilet. I hope this is helpful to you. For more related knowledge, please continue to follow the Hawkrown platform for more exciting content in the future.
