The secret to selecting a flat faucet

2021-04-13 691

A high priced faucet is more expensive than the valve core.

The current type of valve core on the market is ceramic valve core. After use, it has good sealing performance, no dripping, and stable performance in all aspects. All of them are ceramic valve cores.

Simple rusting is actually due to poor surface coating and wire drawing

When choosing a faucet, you will find that although the ingredients are different, they all look silver blinking. Why is this?

It is because the surface has been treated with a process to enhance its strength, and it is not just about accumulated water and dirt. Whether it will rust depends on the process of surface treatment.

The surface of copper faucets will be electroplated, with at least three layers of acid copper plating on the bottom layer, nickel plating on the middle layer, and chromium plating on the surface layer, but no more than five layers.

▲ At least three layers

▲ The thickness is also controlled within the range

Good or bad sex is directly judged by the salt spray test level. If the corrosion area on the surface is less than 0.1 in the 24-hour salt spray test, it is considered qualified, equivalent to reaching the 9th level specification.

The national standard requires a 24-hour salt spray test. The longer the product undergoes salt spray testing, such as 36 hours or 48 hours, the higher the corresponding level.

Nowadays, many manufacturers are cutting corners in the electroplating process, and if the salt spray test results cannot be answered, it may be that they have not even tested.

▲ After 24 hours of salt spray testing, it reaches level 9 specifications

The electroplated surface of the faucet is characterized by high clarity and reflectivity, which can be described as "discernible from light.".

A good coating is generally used for four to five years, and there may be some spots on the surface, but it is generally still shiny. This is the qualified coating, and unqualified faucets will peel and rust within one or two years.

▲ If there are defects on the surface of the electroplating layer, it will easily rust

▲ Various colored faucets have different surface coatings

Stainless steel faucets themselves have anti-corrosion properties, so stainless steel faucets do not require electroplating. Generally, polishing and surface drawing treatment are used to enhance durability and add aesthetics.

The difference between good and bad lies in the wire drawing process on the surface. A high-quality stainless steel faucet has a uniform and delicate wire drawing texture on the surface, which feels smooth to the touch.

Using a defective faucet is equivalent to poisoning oneself

There is a group of people that Ganan is particularly unfamiliar with. They are willing to spend tens of yuan every day drinking happy tea and Starbucks, and spend two to three hundred yuan every weekend eating good meals, but they risk heavy metal poisoning by buying faucets for less than 200 yuan.

The water we drink, cook, and wash fruits every day flows out through the faucet.

The incomplete faucet is mostly made of materials that exceed heavy metal consumption. The water flowing out of such a faucet is equivalent to feeding oneself poison every day!

So when choosing a dragon head, avoid being greedy for cheap prices and choose raw materials.

The leading raw materials for mainstream in the market are mainly 304 stainless steel and copper.

Copper ions in brass have an effect, and some experts say that copper is one of the materials that touch water sources. Essentially, brass faucets are used in Europe and America.

When choosing a faucet, you may hear the salesperson say, "Our faucet is made of all copper and can reach a weight of xxxx. The valve core is imported from Germany and comes with a two-year warranty and a lifetime warranty."

Be vigilant when the salesperson is saying these words. Because the term "all copper" here is not what you think is all copper.

The copper here generally refers to the national standard copper (copper that meets the requirements of GB18145-2014 national standards, copper 59, lead 1, zinc and a few impurities), not 100% pure copper.

Lead needs to be added to brass in order to be processed into a faucet, but it can also lead to the precipitation of lead. Some unscrupulous merchants may use recycled brass with high impurity copper, which can lead to lead oversupply in water.

So it is important to recognize the national standard copper, also known as "59 copper" or "hpb59-1 lead brass", and the price of such faucets usually starts at 300.

▲ 59 copper

Most faucets only use national standard copper for the core body orientation, while other parts such as handles are commonly made of stainless steel or ABS plastic. Product overview labels such as "59 copper for the body" indicate this.

In fact, we did not seek all copper, just use copper for the parts that touch the water. If all copper is used, the price will be very high.

▲ Body 59 copper

When buying a faucet, you may see some merchants writing "clean lead faucet" or "lead-free faucet". Here, "clean lead" or "lead-free" refers to the low lead content, which is lower than the domestic standards.

For example, some leading foreign brands follow the regulations of the US Senate Bill 3874 for lead content, and in pipeline products and accessories, their lead content in the water contact part is not 0.25.

▲ 62 copper

This type of leading product can actually be called a "lead-free faucet", usually certified with the "Lead Free" logo and priced at over 500 yuan.

Another common raw material for faucets is 304 stainless steel, which has a high chromium content. If miscellaneous 304 stainless steel is used, excessive hexavalent chromium may precipitate and damage liver function. Therefore, it is necessary to choose precision cast 304 stainless steel. Kitchen faucets have the SUS304 logo, which is 304 stainless steel.

Wall mounted/pull-out faucet makes cleaning easier

When choosing a faucet, the speed of cleaning should also be considered, as faucets are all used for washing things. In addition to considering the inconvenience of cleaning other things, the cleaning problem of the faucet itself cannot be ignored.

The gaps around the faucet, sink, and washbasin are prone to dirt due to prolonged accumulation of water. However, wall mounted faucets do not have hygiene blind spots, saving a lot of time for cleaning the faucet.

The appearance of the wall mounted faucet is also particularly high, but due to its fixed orientation, replacement and repair are also inconvenient. Before installation, the scale needs to be measured, making it very cool to install in the bathroom.

Another type of faucet that makes cleaning easier and more effortless is the increasingly popular pull-out faucet.

A pull-out faucet that can rotate 360 degrees to spray water looks like a regular faucet, but the front outlet can be pulled out completely. The faucet can be switched through buttons and operated with one hand, making it more convenient.

Install one in the bathroom, which can be easily handled in the washbasin if only washing hair, making it very suitable for girls.

Install one in the kitchen sink, making it more convenient to wash dishes and utensils. The edges and corners of the sink can also be easily cleaned, eliminating dirt and leaving no hygiene blind spots.

If you want the faucet to be more durable, you need these accessories

If the water quality at home is poor, such as a lot of small gravel and severe scale All of these will affect the lifespan of the faucet, especially if you want to buy a high priced faucet, coupled with the following accessories, the lifespan of the faucet will be longer~

/Pre filter/

Pre filter, which can filter out sediment, particles, algae, etc. in tap water, is generally installed behind the water meter in the main inlet pipeline.

If you live in an old residential area that may require secondary pressure boosting, it is recommended to install one, which is not expensive. You can buy a good one for a few hundred yuan.

▲ Yellow represents after use, while white represents before use

Water quality is a topic that we cannot avoid. I have written a very specific article on the whole house water purification system before. Based on the current water quality situation in China, I advocate that everyone take a look

/Bubbler/

If your water quality is good, you can directly choose a faucet with a bubbler.

The bubbler also has a filter that can filter out sediment and impurities, but its function is to allow the flowing water and air to mix thoroughly, giving the water a foaming effect and improving the flushing power of the water, which can save 50% of water usage.

▲ Structure of the bubbler

Generally, the water flow of a faucet is gentle and mist like, without splashing everywhere.
