To fix a dripping water purifier faucet, follow these steps: First, shut off the water supply to avoid flooding. Next, disassemble the faucet by removing the aerator and any retaining rings. Inspect the O-ring seal, diverter valve, and spring mechanism for wear, cracks, or mineral buildup. Replace damaged or worn components with manufacturer-approved parts. Reassemble the faucet, ensuring all parts are tightly secured. Test the faucet by running water to confirm the leak is resolved. If the issue persists, consult a professional.

A dripping faucet typically results from a failing O-ring seal, which fails to prevent water from escaping the valve seat. According to the Environmental Protection Agency (EPA), a single dripping faucet can waste over 3,000 gallons of water annually, contributing to household water waste. A 2021 study by the American Water Works Association found that 60% of faucet leaks are caused by worn O-rings, costing homeowners an average of $200 annually in excess water bills. Additionally, mineral deposits from hard water can erode the diverter valve, disrupting the water flow and creating drips. Regular maintenance, including O-ring replacement every 6–12 months, is critical to preventing leaks. Industry data shows that addressing these issues promptly reduces water waste by up to 80% and extends faucet lifespan by 3–5 years. Proactive repair saves money, conserves resources, and aligns with sustainability goals outlined by organizations like the EPA’s WaterSense program.
