Hello Daniel and thank you for the feedback you posted on the Home Depot website. We are sorry to hear of the difficulty you are experiencing with your Moen Banbury Single-Handle 1-Spray 1.75 GPM Shower Faucet in Spot Resist Brushed Nickel (Valve Included) that started dripping. The most common cause of cartridge failure is due to damage to the rubber o-rings/grommets on the cartridge, which can occur if sediment or debris breaks loose in the water lines or if hard/high mineral content water flows through the faucet. As the original purchaser of the Moen Banbury Single-Handle 1-Spray 1.75 GPM Shower Faucet in Spot Resist Brushed Nickel (Valve Included), you can contact Moen directly under the product lifetime limited warranty. Moen product specialists would be happy to work with you troubleshoot any issues and they would work to find a satisfactory warranty resolution. Please contact us at 1-800-289-6636; we are available Monday through Friday from 8:00 am – 7:00 pm Eastern Time.
