To install a water purifier faucet on a kitchen sink, first shut off the water supply by closing the shut-off valves under the sink. Open the main faucet to drain remaining water. Remove the existing faucet by unscrewing the supply lines and демонтаж the base. Attach the purifier faucet’s base to the sink using the provided brackets and screws, ensuring it’s level. Connect the water lines to the purifier’s inlet ports, using plumber’s tape to seal connections. Secure the supply lines with screws and turn the water back on to test for leaks. If leaks occur, tighten connections or recheck alignment. Finally, install the aerator on the faucet head.

Proper installation ensures optimal performance and safety. According to the Centers for Disease Control and Prevention (CDC), contaminated water causes 48 million illnesses annually in the U.S., emphasizing the need for reliable purification systems. A study by the Environmental Protection Agency (EPA) found that 30% of home water leaks stem from faulty fixtures, leading to $100–150 in annual water waste per household. Correctly attaching the purifier faucet prevents cross-contamination risks, as improper connections may allow unfiltered water to bypass the system. The Journal of Water Resources Management reports that 25% of DIY installations suffer from leaks, increasing maintenance costs by 20%. Additionally, the EPA estimates that using a certified purifier faucet can reduce lead exposure by 99%, protecting households from health risks linked to aging plumbing. Ensuring precise alignment during installation maintains flow efficiency, with the International Association of Plumber’s estimate that well-fitted faucets reduce water usage by 15%. Adhering to these steps balances cost-effectiveness and safety, aligning with industry standards for residential water systems.
