Hi BillA07422,
We want to help and get more details about the corrosion and leaking on your faucet. As the original owner, your Pfister faucet is backed by our Limited Lifetime warranty, which protects the finish and function for as long as you own it. We'd be happy to help resolve this, but we need more information and pictures. Please contact our Support Team at 1-800-732-8238 at your earliest convenience.
Thank you,
Pfister
