Rated 4 out of 5 by from Sprayer leaks I was talked into the Delta 21988LF and paid the extra money for it. It was easy to install and looked great. It worked great until after 9 months. Then the sprayer would not stop leaking from the on/off button. I wrote to customer service and hope to get it replaced very soon.

can this faucet be installed without the sprayer

Asked by: mitch
Dear Mitch, Thank you for your inquiry! The Delta Foundations Kitchen faucet 21988LF-OB can be installed without the side vegetable sprayer. However, you would need to purchase the RP60295, to cap off the nipple below the faucet. Best regards, Tanya

Howdy, Are the spout, handles, & base of this faucet made of brass, or is the finish applied to a different base metal? I've read that the sprayer is plastic, but is the rest of the faucet all metal? Much obliged, Matt

Asked by: tomhorn1913
(Foundations 21988LF) -The spout and handles are NOT internally metal, but instead plastic. This was confirmed to me by a Delta phone representative.
