I bought this faucet back in 2005. Over time the diverter became clogged to the the point that water was not coming out at all. We shopped for a new faucet but I didn't see anything I liked as well, and then a sales rep at a high end kitchen and bath store told me about Pfister's lifetime guarantee. We submitted proof of purchase and photographs, and within several days, received a brand new faucet! We also purchased a couple of extra diverter assemblies so that we could nip the problem early the next time.
