What's the Diameter of a 4-Inch Fauce

In the installation process of a faucet, it is essential to understand its diameter to avoid issues with fitting. Below, I will explain the diameter of a 4-point faucet.

What is the diameter of a 4-point faucet?

The diameter of a 4-point faucet is approximately 12.7 millimeters. The imperial system does not have a unit called “point”; instead, it typically uses fractions of inches, such as 1/2, 1/4, 1/8, etc. In this case, 4 points corresponds to 1/2 inch. Since 1 inch equals 25.4 millimeters, a 4-point faucet is calculated as 1/2 inch, which equals 12.7 millimeters.

What are the differences between a 4-point faucet and a 6-point faucet?

1. Different Diameters

These two types of water pipes not only have different names, but their diameters also differ. The diameter of a 4-point pipe is relatively smaller, approximately 20 millimeters. In contrast, the diameter of a 6-point pipe is larger, approximately 25 millimeters. Thus, there are some differences in their installation as well.

2. Different Application Areas

Since their diameters differ, the usage of these pipes is also distinct. For instance, in a unit with one kitchen and one bathroom, if there is space for a washing machine or a sink on the balcony, the water supply to the house is typically split into two routes: one for the kitchen and the other for the bathroom. It is recommended to use a 6-point pipe for the water supply to the bathroom. The water pipes in the kitchen can use a 4-point pipe, which is also suitable for piping from the water heater to the kitchen sink or the bathroom basin.

3. Different Residential Characteristics

Even within the same community and building, there can be distinctions between high and low floors. If a home is on a higher floor, it is advisable to use a 6-point pipe to prevent water supply issues due to insufficient water pressure. In contrast, for villas or self-built houses, a 4-point pipe can suffice.

In summary, the content regarding the diameter of a 4-point faucet has been introduced here. The diameter of a 4-point faucet is approximately 12.7 millimeters, which arises from the fact that 1 inch equals 25.4 millimeters, and thus 4 points equals 12.7 millimeters.
