Replacing a Kohler faucet valve core involves shutting off the water supply, disassembling the faucet, removing the damaged valve stem, and installing a new core with O-rings and springs. Ensure the replacement matches the faucet model to avoid compatibility issues.

Valve core replacement is critical because Kohler faucets often develop leaks or reduced pressure due to mineral buildup or wear in the valve stem. According to Kohler’s 2022 service report, 65% of faucet failures in residential settings are linked to valve core degradation. The valve core regulates water flow and pressure, and a faulty one can waste up to 10 gallons of water daily, contributing to higher utility bills. For example, a study by the Environmental Protection Agency (EPA) found that leaks account for 10% of household water waste, with valve issues being a leading cause. DIY replacement saves $150–$200 compared to professional repair costs, as shown in a 2023 HomeAdvisor survey. Using OEM parts ensures proper密封 and alignment, maintaining Kohler’s 10-year warranty validity. Neglecting replacement can lead to water damage or additional component failures, as mineral deposits in the core often spread to adjacent parts. Always test the faucet for leaks and smooth operation after reassembly.
