I have a Price Pfister kitchen faucet that I had put in about 1 year & a half ago; its leaking where the water runs up into the faucet; had a plumber order the part & replace; it still leaks. Can you please tell me if this is lifetime warranted. I do not have the receipts; went to Home Depot & they told me to check with Price Pfister. I have to repace the whole outfit & when I bought the other one I was told it was lifetime guaranteed (that's the only reason I bought it). Thanks for any help you provide me.
