Are Floor Drains and Downspouts Connected or Separate?

The floor drain is one of the most commonly used building materials in home life, found in kitchens, bathrooms, and balconies. It significantly affects drainage issues. Should the floor drain be distanced from or connected to the drainage pipe?

Are Floor Drains and Downspouts Connected or Separate?

1. Regardless of whether it is installed in the kitchen or bathroom, the floor drain should have a certain distance from the drainage pipe and should not be directly connected. There should be a suitable connecting method between the two. When choosing a floor drain, it is essential to select the appropriate specifications based on the diameter of the drainage pipe, which is generally 50mm PVC. If the material chosen is cast iron, its diameter will typically be slightly larger. When selecting the floor drain, it is important to consider the size of the drain outlet rather than modifying the outlet first and then choosing the floor drain.

2. Additionally, it’s important to set a certain slope to facilitate drainage. Ensure that there is an appropriate slope around the floor drain so that water flows downwards. The installation of floor tiles and the floor drain should be performed simultaneously. A layer of cement can be applied to the back of the floor drain before placing the floor drain cover over the drainage outlet for securing it. For sealing, materials like silicone sealant can be used to ensure effective sealing, thus preventing future water leakage issues.

Types of Floor Drains

1. There are many types of floor drains. Although often overlooked during renovations, they are a necessary component connecting the entire drainage system. Choosing the right one can lead to excellent bathroom conditions, while a poor choice may result in unpleasant odors.

2. One type of floor drain can be closed when not in use and automatically opens when needed. It has a long lifespan and good odor prevention capabilities, all at a reasonable price. Another type is the water seal floor drain, which can automatically open and close through the drainage outlet. The main materials used are stainless steel or brass, making it less likely to experience backflow issues.

In summary：there are many types of floor drains, such as silicone floor drains, flap floor drains, concealed floor drains, and bouncing floor drains, among others. Each type has its performance characteristics and features.
