Faucet can be said to be one of the most frequently used kitchen and bathroom equipment in every household. Whether its quality is qualified and its design is reasonable will have a long-term impact on the health and quality of life of the whole family.

CCTV once broadcasted a program that tested the overnight water of 10 households, and found that 3 households had water samples with excessive metal pollutants - lead precipitation!

Is choosing a wrong faucet equivalent to drinking toxic water every day? Which faucets are toxic (excessive lead precipitation)? What are the considerations when choosing a faucet? Just look below and you'll know.

Long term consumption of tap water with excessive heavy metals poses a health hazard

Under normal circumstances, tap water is weakly acidic, and if left in the faucet for a long time, it is easy for metal pollutants in the faucet to precipitate and dissolve into the water, causing water pollution.

Previous studies have shown that long-term use or consumption of tap water with excessive levels of metals, especially heavy metals, is highly likely to pose a threat to human health.

From the perspective of lead, if lead exceeds the national standard limit, it can easily cause damage to the brain and nervous system. Long term consumption of tap water containing lead increases the risk to human health over time.

Therefore, China's testing standards for faucet materials stipulate that components that come into contact with water should not use corrosive materials such as zinc alloys, should not pose a threat to human health, and should not cause any changes in water quality, appearance, taste, smell, etc. in drinking water.

How to choose a healthy, safe, and practical faucet?

When selecting a faucet, the first thing to do is to choose the right material. Currently, the most common faucet materials on the market mainly include copper alloy, stainless steel, and so on.

Copper alloy faucet material

Features: Non rusting, durable, with antioxidant and bactericidal effects on water.

Disadvantage: Lead content! It is best to choose a reputable brand when purchasing to ensure that the lead content does not exceed the health standard of 5ug/L.

Stainless steel faucet

Features: High hardness, strong toughness, no rust, no lead, and the faucet itself will not cause secondary pollution to the water source.

Disadvantage: It is difficult to manufacture and process, so the price is higher than other materials of faucets.

Suggestion: From a safety and health perspective, it is recommended to choose stainless steel faucets from reputable brands when purchasing faucets. You can request the product certification certificate issued by the national quality inspection department from the merchant.

There are rules to using the faucet in the morning

When using the faucet every morning, it is best not to use the "overnight water" that is stuck inside. You can leave the faucet empty for a while and use this water to flush the bathroom, mop the floor, etc.

The connecting hose of the faucet is also prone to exceeding the standard

Professional inspectors remind that the connecting hose of the faucet is also very important and must be paid attention to when purchasing.

Liao Ronghua (the main drafter of the national standard "Ceramic Sealed Water Nozzles") reminds that faucet hoses are made of different materials, some are very sturdy, some are easy to tear, and those that are easy to tear may be made of secondary materials, which can easily lead to excessive organic matter. When making a purchase, pick it up and smell it. If the smell is too strong, it may result in poor quality, so it is best not to buy.
