Think of the faucet cartridge as the heart of your faucet. How durable it is largely determines how long your faucet will last. In fact, most faucets available on the market meet the GB18145 standard, which ensures they are designed to handle years of normal use.
Here is how the calculation works:
| Calculation | Details |
| Cartridge Lifespan | 70,000 cycles (each cycle includes 3 on/off actions, total of 210,000 on/off actions) |
| Daily On/Off Actions | Assumes 50 on/off actions per day |
| On/Off Actions per Cycle | Each cycle includes 3 on/off actions |
| Annual On/Off Actions | 50 times/day × 365 days = 18,250 actions/year |
| Estimated Cartridge Lifespan | 210,000 actions ÷ 18,250 actions/year ≈ 11.5 years |
As long as the other parts are of good quality and the faucet is used properly, it should last around 10 to 12 years.
Another important factor in determining how long a faucet lasts is the material it is made of. The most common options for faucet materials are copper and stainless steel.
Copper:
Low-Grade Brass: Contains approximately 55 percent copper and more than 3 percent lead. This composition is harmful to human health and does not meet safety standards.
GB 59-A Grade Copper: Contains at least 59 percent copper with 1.0 to 1.6 percent lead content, meeting national standards for safety.
Lead-Free Copper: Contains at least 59 percent copper and less than 0.25 percent lead. This is the highest material standard and complies with United States drinking water safety regulations. It is more difficult to process and has higher costs, which is why only a few manufacturers can produce faucets using lead-free copper.
Copper quality directly impacts the faucet’s plating and its resistance to oxidation. Lower-quality copper can lead to issues such as peeling plating or surfaces that become blackened due to oxidation.
Stainless Steel:
201 Stainless Steel: Contains about 5 percent nickel, which makes it prone to rusting.
304 Stainless Steel: Contains at least 8 percent nickel and offers excellent resistance to rust.
If the material used for the faucet does not meet the required standards, the faucet is unlikely to last as long as it should.
At Coign, we are proud to be one of the few manufacturers capable of working with both lead-free copper and stainless steel. These materials are difficult to process, but we are committed to using the best to create faucets that stand the test of time.
From selecting top-quality materials to ensuring every small detail is carefully handled during production, we guarantee that each faucet meets or exceeds industry standards. Our goal is simple: to provide faucets that are durable, safe, and built to last for many years.
When you choose Coign, you are not just purchasing a faucet—you are making an investment in a product crafted with care, precision, and a commitment to quality.
