For heavily used kitchen faucets, the most durable finish is undoubtedly PVD coating. Watersino utilizes advanced PVD coating faucet technology to create classic colors like polished nickel PVD. The PVD layer is extremely wear-resistant, corrosion-resistant, and scratch-resistant, easily withstanding daily wear and tear in the kitchen and exposure to chemicals, ensuring your faucet finishes look new year after year. It is an ideal choice for long-lasting, sustainable solutions
It’s recommended to close the inlet valve, drain the water from the pipe, and wipe the surface dry with a soft cloth. If it won’t be used for an extended period, run the water for a short time periodically (e.g., once a month) to prevent the seals from aging and scale buildup.

At Watersino, the core of our faucet valve bodies is crafted from a uniquely formulated NZR-free and lead-free natural brass. This material choice is fundamental to delivering unparalleled water safety and long-term reliability.
Here’s how it works:
Ensuring Water Safety:
By rigorously excluding nickel (Ni) and lead (Pb), our brass material prevents these harmful heavy metals from leaching into your drinking water.
This commitment to purity allows our products to meet and exceed the world’s most stringent drinking water safety standards, including NSF/ANSI 61.
Guaranteeing Durability & Longevity:
The exceptional purity of the material grants it excellent corrosion resistance. It stands up to water corrosion and scale buildup, ensuring consistent performance over time.
This inherent robustness significantly extends the product’s lifespan and enhances overall operational reliability, reducing the risk of leaks and failures.
In short, our special material is not just about safety; it’s a core investment in a more durable and dependable product for your home.
While many brands use standard brass to reduce costs, Watersino’s insistence on premium NZR-free and lead-free natural brass is a non-negotiable core commitment. This choice defines our brand and stems from two key differentiators:
- An Uncompromising Standard for Water Safety
Ordinary brass can leach trace amounts of heavy metals like lead and nickel into water over time. For Watersino, “safe enough” is not sufficient. By eliminating these contaminants from the source material, we provide a fundamental guarantee for your drinking water’s safety and ensure compliance with the world’s most rigorous certifications, such as NSF/ANSI 61. We believe what touches your water should be as pure as the water itself.
- A Commitment to Superior Long-Term Value
While the initial cost of our material is higher, it delivers exceptional long-term value through enhanced durability and reliability.
Purer Material, Superior Corrosion Resistance: The absence of impurities makes the brass itself more stable and significantly more resistant to corrosion and scaling.
Extended Lifespan & Consistent Performance: This inherent robustness prevents common issues like leaks and mineral buildup, ensuring smooth operation for years and ultimately reducing the need for replacements.
For Watersino, this isn’t just a material choice—it’s the foundation of our promise to deliver a safer, more reliable, and truly durable product for your home.
We ensure electroplating quality through end-to-end quality control:
Precision Pre-treatment: Utilizing fully automated ultrasonic cleaning ensures the substrate is free of stains, laying the foundation for high-quality electroplating.
Standard Electroplating Process: Strictly adhering to a multi-layer electroplating process of “copper + nickel + chromium,” where the nickel layer is crucial for corrosion resistance, and its thickness and uniformity are rigorously monitored.
Automated Production: Fully automated electroplating lines precisely control various parameters, minimizing human error and ensuring batch consistency.
Our electroplated products strictly adhere to standards exceeding industry norms:
Regular Products: Pass ≥48 hours of neutral salt spray testing, showing no rust or peeling.
High-end Products: Pass ≥72 hours of acidic salt spray testing, meeting more demanding usage environments.
