Is the 4-Factor Faucet Compatible with 20mm Connections

The faucet is a commonly used tool in households, designed for easy connection to water pipes. So, is a 4-point faucet equal to 20? How should one choose a faucet? Let's take a look.

Is a 4-point faucet equal to 20?

No, a 4-point faucet corresponds to a size of 15mm, which is 1.5 centimeters. It is mainly used in household water filling interfaces, such as washing machine water pipe connections. During installation, you only need to remove the old faucet and install the special faucet to connect to the water filling pipe. However, different washing machines have different pipe connections, and some may require a 6-point faucet. You can choose based on the actual situation.

Faucets are usually categorized into 4-point and 6-point types. The former has an outer diameter of about 23mm and an inner diameter of 15mm. The latter has an outer diameter of about 26mm and an inner diameter of 20mm. When purchasing, it’s best to measure the inner diameter of the threads with a caliper to select the corresponding faucet.

How to choose a faucet:

1. Look at the material

Faucets on the market are made of plastic, cast iron, and copper, among other materials. Plastic faucets are prone to aging and breakage. Iron faucets are susceptible to rust and can contaminate the water quality. Copper faucets, on the other hand, are heavy-duty, have mature manufacturing processes, and are environmentally friendly and corrosion-resistant, making them more favored by consumers.

2. Examine the valve core

When choosing a faucet, pay attention to its valve core, which typically comes in ceramic and steel ball types. It is recommended to opt for a ceramic valve core, as it is resistant to corrosion and high temperatures, and has a long service life while also preventing leaks. Although steel ball valve cores offer good performance, they have a shorter lifespan and are prone to dripping.

3. Check the aerator

Look at the faucet's aerator. A good aerator can prevent splashing, reduce noise, and contribute to water saving or filtering out impurities from the water. During purchase, you can perform a water test; if the water flow produces lots of bubbles, this indicates good aerator quality.

4. Inspect the surface

Examine the faucet's surface; a good faucet will have a layer of nickel or chromium plating that not only prevents corrosion but also keeps the faucet looking shiny and new.
