The Ultimate Guide to Repairing a Leaking Bathroom Floor Drain

Toilet floor drains are familiar to everyone as they are an essential drainage channel. Let's take a look at how to repair leaks in toilet floor drains.

How to Repair Leaks in Toilet Floor Drains

1. Start by performing a local water-sealing treatment on the floor drain. Use a plastic bag to block the drain, then fill the area with water and observe whether improper waterproofing around the drain is causing the leak.

2. If the leak is due to inadequate waterproofing around the drain pipe, use a chisel to chisel out a ring-shaped groove about 2-3 cm wide around the drain.

3. During the chiseling process, if there is any looseness around the pipe, continue chiseling. Clean the groove thoroughly with a brush. Mix the waterproof agent into a paste and fill the groove, using the waterproofing agent to seal the area and pressing it firmly and smoothing the surface.

4. If the leak is caused by a damaged drain pipe, first, pry up the floor tiles near the drain and excavate a space about 3 cm deep. Then apply a leak-sealing product and let it sit for about an hour for a water-sealing test to check for any further water seepage. If the seepage continues, the drain pipe will need to be replaced, which should be handled by a professional.

Installation Precautions for Floor Drains

1. Ensure the floor is properly sloped, with the floor drain located at the lowest point of the bathroom. The slope should be set within 5 degrees to allow water to flow naturally downward.

2. Confirm the size of the floor drain to ensure it matches the pre-installed drainage pipe; the standard drainage pipe diameter is 5 cm. When laying tiles, pay attention to the alignment of the floor tiles with the wall tiles. Cut ceramic tiles according to the dimensions of the drain to ensure a perfect fit.

3. Apply cement mortar around the floor drain where it connects to the drainage pipe to ensure a tight seal.

4. After laying the tiles, gently tap the floor tiles with a hammer to ensure the mortar bonds fully and to prevent any hollow areas.
