The source of a water leak can be determined by testing a water meter. If the meter continues to run after turning off all water-using appliances, there is a leak in your home. At this time, you should check the bottoms of cabinets in the kitchen, laundry room, and bathroom for moisture, and pay attention to whether there is water accumulation around bathtubs, toilets, showers, water heaters, dishwashers, and washing machines. Our gooseneck copper kitchen faucets feature a single-hole countertop design with a ceramic valve core and a zinc alloy single handle. They are easy to operate, and the water spout can be rotated to adjust the direction of water flow. The surface can be chrome-plated or customized in color, making them suitable for a variety of locations such as villas and apartments. This product comes with a five-year warranty and supports customization. Please feel free to inquire. Our kitchen faucet series is easy to install in various basins and sinks, providing a durable and efficient water experience.
