Thank you for your question. If the 144938-I20 faucet leaks, we recommend to first flush the valve to make sure no debris maybe causing the leak. To flush, first turn the water off at the supplies, remove the handle and unscrew the bonnet nut off of the valve body. Pull the cartridge assembly straight out of the valve. Turn the water on at the shut off valve and let the water flush for 30-45 seconds. Shut off the water and reinstall all parts. If this does not fix the issue, we recommend to then replace the seats and springs, RP4993, inside of the cartridge.
