I purchased the faucet 7 years ago. I was happy with it until just recently. The sprayer was not working. I replaced the sprayer with one I purchased online. However, it still would not work. It was the faucet not the sprayer. I finally called pfister for an internal part. I was very surprised to learn it was under warranty. The part was not available and the company replaced the entire faucet at no charge. I was very impressed with the customer support.
