Rated 5 out of 5 by from Solid Mid Range Faucet I've had it for more than 4 years and it's a great leak free faucet with smooth operating handles. The sprayer did develope a small leak and Delta sent me a replacement, no questions asked. Excellent product and even better customer service.

Rated 5 out of 5 by from Works great!!! Bought a cheap faucet about 2 weeks ago. Yea I know. You get what you pay for. But this faucet was not much more than the cheap faucet I bought.Should have went with this one first. Didn't care for the Crooked neck, but turns out I love it.

Rated 5 out of 5 by from GREAT FEATURES AND SUPER EASY INSTALLATION We are so happy that we chose a Delta Faucet over all other faucets. We had a plumber install it and in his opinion, it is the best faucet on the market! We love the ease of use and the stainless steel appearance.

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.
