Understanding the Differences: Deep Seal vs. Shallow Seal in Shower Drains

In our daily life, we often encounter floor drains, and the performance differences between various types of floor drains can be significant. So, should a shower floor drain use a deep seal or a shallow seal?

Should a shower floor drain use a shallow seal or a deep seal?

It is advisable to choose a deep seal. According to relevant domestic standards, the height of the floor drain should reach 5 centimeters, and a shallow seal cannot meet this standard and is prone to drying out. High-rise residential buildings must ensure that the height of the drainage pipes below is sufficient to install a deep seal floor drain. If the height is insufficient but you still want to achieve better performance, you can opt for a magnetic floor drain available in stores, which can ensure a good sealing effect.

What aspects should be considered when purchasing a floor drain?

1. There are many types of floor drains available on the market, and their functions vary. Generally, they can be divided into two categories: ordinary and washing machine specific. The latter typically has a removable round cover in the center, allowing the washing machine's drainage pipe to be inserted, which does not interfere with the drainage of surface water.

2. The materials used for floor drains vary as well, including cast iron, PVC, ceramics, and stainless steel, among others. Among these, floor drains made of stainless steel and copper alloys are reasonably priced, visually appealing, and durable. However, when considering overall performance, brass floor drains tend to be the best.

3. The primary purpose of a floor drain is to prevent debris from entering the drainage pipes and to facilitate drainage. If the drainage speed is too slow, it can lead to water overflowing everywhere. Therefore, when selecting a floor drain, it is crucial to ensure that the central space of the drain is large enough to prevent any obstruction to water flow.

4. Over time, floor drains can harbor bacteria, leading to unpleasant odors. Hence, when making an actual purchase, it is important to consider odor prevention aspects as well.

In summary：the above information pertains to floor drains. From the article, we can see that a deep seal should be prioritized for shower floor drains since a shallow seal cannot meet the relevant standards. However, when choosing a floor drain, it is important to consider multiple aspects to ensure smooth drainage while preventing odors. I hope this information can be helpful to everyone.
