Over three years with this faucet and the diverter valve located within the faucet handle repeatedly fails and causes less than adequate water flow from the faucet. This is obviously a design flaw or the replacement part is so poorly made, a 3 month life is typical. My repeated issues result in a new worthless part to get me by for another three months that I have spend time installing. I gave up and have lived with poor water flow or a hand sprayer in the kitchen. Pfister never again!!
