The most common leak is a drip from the end of the spout. This drip can usually be fixed by replacing your stem or cartridge, which turn on and off the water in the faucet. You need to determine whether it is the hot, cold or both sides causing the leak. You can then remove the stem or cartridge, which lies beneath the handle and locate a store near you that carries our replacement parts, or you can call Customer Service at 800-888-4458 to obtain information on replacing the stem/cartridge. For warranty information, please refer to your warranty cards sent with the faucet.
