Troubleshooting Kohler Coralais

Replace the cartridge on the Coralais faucet if you notice leaking around the faucet. Shut off the water supply under the sink. Remove the handle by unscrewing the set screw using a hex key, then pull the handle out. Remove the cartridge from the faucet body with needle nose pliers, then replace it with a new cartridge. Reassemble the faucet assembly and turn on the water.

Unscrew the aerator at the bottom of the faucet spout with pliers if you’re experiencing low water pressure. Tap the screen out on a counter or other hard surface to remove any dirt or sediment. Rinse the screen under clean water at another faucet before screwing it back onto the Coralais faucet.

Replace the spray hose on your Kohler Coralais faucet if it is leaking. Turn off the water, then turn the spray hose counterclockwise from beneath the faucet to remove it. Remove the hose from the holder and insert a new spray hose and head. Secure the new spray hose in place by screwing it into the threading under the faucet in a clockwise direction.
