As of October 2015, Moen faucets come with a lifetime limited warranty. The company guarantees the faucet to be leak- and drip-free during the time the original purchaser owns the home where the faucet is installed. Moen declares that the faucet has been manufactured properly without defective material.
If the faucet does leak or drip, Moen promises to supply any necessary parts for repairing the problem without cost to the consumer. The company also agrees to replace any faucet that is defective. The warranty does not cover deficiencies or damage if the installer does not use all Moen parts. Industrial, commercial and business purchasers receive a five-year warranty.
