How to Replace a Kohler Coralais Kitchen Faucet Cartridge
Kohler's Coralais faucet line has a cartridge right inside the faucet body that regulates temperature and water flow rates. This cartridge is the faucet's main valve, and it is replaceable. If the faucet leaks or has problems delivering the right temperature, consider replacing this fairly inexpensive part. It only takes about 20 minutes to complete the entire repair and all you need is a few regular household tools. This repair does not require a plumber or contractor. Does this Spark an idea?
