Recognizing and Repairing Damaged Pipes Beneath Your Floor Drain

If there is a problem with a leaking or damaged pipe under the floor drain, here’s how to repair it

Repairing a Rotten Pipe Under Your Floor Drain: Essential Techniques and Tips

1. If the pipe underneath the floor drain is damaged, it needs to be replaced. Before replacing it, check the specifications of the existing pipe, as it may be necessary to replace the entire floor drain.

2. First, turn off the household water supply. Use a screwdriver to detach the floor drain cover from the junction with the tiles. After cleaning the area, remove the old water pipe and replace it with a new one.

3. Generally, it is not recommended to use cast iron material, as it is more prone to corrosion. It is better to choose PVC material, which is not easy to corrode. If there are also clogging issues, PVC can be easily cleaned. If the floor drain needs to be replaced, you can replace it at the same time. Finally, reinstall it and make sure to fill and seal the area around the drain properly to prevent future leaks.

To unclog a blocked floor drain

1. If the floor drain in the bathroom is clogged, first try to unclog it by using a thin piece of wire to reach inside and pull out the blockage. Alternatively, you can use a stick that is similar in size to the drain pipe and push it up and down to help clear the blockage.

2. If the unclogging is not very effective, prepare a mixture of baking soda and white vinegar, then add hot water and stir well before pouring it into the drain. These two substances can effectively dissolve some of the clogs in the pipe. After waiting a while, flush the drain with more water to see if it clears.

3. If the problem still persists, consider contacting a professional drain cleaning service. They have experience and professional equipment that can resolve the issue.

In summary：if you discover damage or problems with the pipes under the floor drain, it is essential to replace the pipe directly. If repairs are ineffective, replacing it with a new one is the best solution.
