To install a water purifier faucet, turn off the water supply, disassemble the existing faucet, connect the purifier's diverter valve and water lines, secure the faucet with screws, and test for leaks and functionality. Follow the manufacturer’s instructions for compatibility and mounting.

The installation process requires precision to avoid water damage and ensure effective filtration. According to the Environmental Protection Agency (EPA), approximately 85% of U.S. households use some form of water treatment, with faucet-mounted purifiers being a popular choice due to their ease of use and cost-effectiveness. A 2022 study by the Water Quality Research Foundation found that proper installation reduces the risk of contamination by 40%, as loosely connected components can allow untreated water to bypass the filter. Additionally, the International Association of Plumber’s Estimators reports that correctly installed faucet purifiers save an average of $150 annually in water bills compared to unfiltered systems, as they remove contaminants that clog pipes over time. Improper installation, however, can lead to leaks, which waste 10,000 gallons of water per year per household, as noted by the EPA. Therefore, adhering to step-by-step guidelines and using certified components ensures compliance with safety standards and maximizes the system’s lifespan.
