How to Address a Section of Pipe Missing Below the Floor Drain?

The floor drain is a common hardware product in daily life, mainly used for draining water from the drainage pipe. What should you do if there’s a short section without a pipe under the floor drain? What are the installation considerations for floor drains? Let’s take a look at these two questions together!

What to do if there’s a short section without a pipe under the floor drain

You can level the pipe end under the floor drain, apply adhesive, and reattach a new short pipe and pipe clamp to fit into the drainage outlet. Alternatively, you can reinstall a P-trap on the pipe under the floor drain to resolve water seepage issues. You can also choose a deodorant floor drain, which not only solves water seepage but also prevents odors.

What are the installation considerations for floor drains

1. Choose the appropriate size of the floor drain

First, select the specification of the floor drain according to the drain opening. Floor drains usually consist of a main body and a cover. During installation, the water in the water seal should be filled to the appropriate depth to allow the floor drain cover to have a certain floating space, thus achieving better drainage.

2. Use cement wisely

Secondly, when installing the floor drain, it's important to use cement properly. Since there is a gap between the floor drain and the drainage pipe, cement can be used to fill it. However, be sure to control the amount of cement used; avoid using too much or too little. Additionally, the height difference between the floor drain and the ground should not be too large, as this will also affect drainage. Generally, a difference of about 2 millimeters is ideal.

3. Prevent unpleasant odors

Finally, since drainage systems are often hidden and may be overlooked during renovations, improper handling can lead to unpleasant odors indoors later on. To avoid strong odors from the drainage pipes in the future, ensure that the drainage pipe is sealed well with adhesive at the drainage outlet to prevent gas from escaping. Also, since the main function of the floor drain is to drain water, the installation level must be lower than the ground. If the drainage pipe is too close to the ground, it should be cut shorter to facilitate drainage.

In summary：the above is an introduction to what to do if there’s a short section without a pipe under the floor drain and the installation considerations for floor drains.
