PVC Pipe Sizing Guide: What You Need for Floor Drains

When installing a floor drain, it is important to choose the right size of pipe to avoid issues such as improper installation. Next, we will introduce the suitable size of PVC pipes for floor drains.

Size of PVC Pipe for Floor Drains

You can use a 50mm PVC pipe. When choosing a floor drain, it is advisable to select one that is easy to disassemble, making it easier to clean when blocked. Additionally, pay attention to the material of the floor drain; it is best to choose one made of brass, as this type has a longer lifespan and is less prone to corrosion.

How to Choose a Floor Drain

1、Carefully Check the Material of the Floor Drain

When selecting a floor drain, make sure to check the material. Currently, floor drains on the market can be made from stainless steel, PVC, brass, and other materials. The prices and performance of different materials vary, so you can choose a suitable material based on your specific situation when purchasing.

2、Pay Attention to the Size of the Floor Drain

Floor drains have standard sizes, so when buying a floor drain, you should choose according to these dimensions. If the selected size is incorrect, it can be troublesome, and you may need to rework the installation. Therefore, before purchasing, you can visit the market to select the appropriate floor drain and inform the renovation workers to adjust the drainage hole according to the size of the drain.

3、Consider the Hole Size of the Drain Grate

The holes in the drain grate should ideally have a diameter of 6-8mm. If the hole diameter is larger than this, it may allow hair and other debris to flow into the drain along with the water, leading to blockages in the sewer and poor drainage performance.

Types of Floor Drains

1、Spring Drain

This type of drain uses a spring mechanism; when the weight of the water exceeds the spring tension, the spring compresses, opening the sealing pad for automatic draining.

2、Magnetic Drain

In this drain, when the water pressure exceeds the magnetic force, the sealing pad will allow for drainage. Conversely, when the pressure is less than the magnetic force, the sealing pad will lift.

3、Gravity Drain

This type of drain operates using gravity, where the flow of water opens a float inside the drain, allowing for automatic drainage.
