In commercial kitchens, restaurant back-of-house areas, school cafeterias, and food processing facilities, manual faucets are required to withstand frequent operation every day while being continuously exposed to water, grease, cleaning agents, and humid environments. Therefore, their service life directly affects kitchen efficiency and long-term maintenance costs.A durable manual faucet can significantly reduce the frequency of repairs and replacements, minimize downtime caused by equipment failures, and improve the overall user experience. When selecting a manual faucet, many users tend to focus mainly on the material or price, assuming that choosing stainless steel or brass automatically means better durability.
