Recently, many copper faucets in the sanitary ware market have been made from leaded brass, and some even use yellow copper, significantly increasing the lead content in the faucet. This has raised concerns among consumers, prompting many to seek practical solutions to ensure their water is safe.
1. Let the Water Run Overnight
Choosing a safe and reliable faucet has become a major concern for many. According to medical experts, one effective method is to "let the overnight water run." Industry professionals agree that while flushing the faucet can reduce lead levels, it's impossible to completely eliminate it. Over time, faucets can accumulate water, which may absorb heavy metals. To be safe, it's recommended to let the water sit in the faucet overnight and then flush it out before using it the next day.
2. Request Third-Party Testing
Following the recent incidents of excessive lead in faucets, most brands have conducted internal inspections and source checks. According to Jiuzheng Building Materials Network, national testing centers typically take five working days to complete a test. In addition to waiting for the results from retailers, if you're unsure about the safety of your faucet, you can contact the Shanghai Quality Supervision and Inspection Technology Research Institute at 12365 for independent testing. The cost for a single test is around 1,000 RMB, but it's a small price to pay for peace of mind.
3. Inspect Carefully Before Purchasing
Industry experts advise buyers to carefully examine the surface finish of the faucet. A high-quality finish should be smooth and shiny, with no visible scratches or imperfections. Pressing on the surface with your finger should leave no mark. Additionally, always ask the salesperson for the product’s test report, brand certification, and after-sales service information. If the test report confirms the faucet meets safety standards, you can use it confidently.
Simple Home Methods to Test Water Quality
Use Soapy Water
One easy way to determine if your water is hard or soft is by using soapy water. Hard water (high in calcium and magnesium) will not lather well, while soft water will produce more suds.
Check for Scale in Kettles
Inspect the inside of your kettle and water heater for any yellowish scale buildup. If present, this indicates that your water is too hard and may need to be treated with a water softener.
Use an Acid-Base Indicator
A simple and effective way to check the pH level of your tap water is by using an acid-base indicator. These are available at most hardware stores and provide quick results.
Make Tea with Tap Water
After the first use of the day, try making tea with your tap water. If the tea turns dark or black, it could indicate that the iron or manganese levels are too high, which may affect both taste and health.
