Hello wowly,
We appreciate you taking the time to share your experience with your Delton faucet. Pfister stands behind its products with our Pforever warranty. The first step of our warranty is to offer replacement parts that will help resolve the issue. Many issues do not affect the whole faucet, and that is why we do not offer whole faucet replacements as a first response. There are exceptions, such as if the entire faucet is defective, or if the replacement parts did not fix the issue. Our Pforever warranty does not cover labor costs, but our team of skilled agents will help you with any installation questions you may have and can walk you through the process. You can learn more about Pfister's Pforever warranty here: https://www.pfisterfaucets.com/support/warranty. If you have any additional questions you can contact our consumer support team at 1-800-PFAUCET (1-800-732-8238).
Thank you, Pfister
