Rated 2 out of 5 by from Cheap metal corrodes easily This the second one i have went through in 3 years. I had to buy a complete unit simply to replace the faucet tube itself.. Planned obsolescence.

Rated 5 out of 5 by from This product is durable, good looking, performs great and is reasonable priced. I bought Delta because of its reputation for making a great product and they stand behind their products. I have bought Delta products for many years.

Rated 5 out of 5 by from Kichen faucet Love the faucet especially the 2 handles on each side. The color is perfect. We still have the original Delta facets in our bathrooms and they are 17 years old and look new. Thanks Delta

Rated 5 out of 5 by from Nice looking, easy to install and works! The other day, I was under my sink to get a cleaning bottle out and found my sink was leaking. New sink, new faucet. Went to the two handle with sprayer. Looked nice and works great, not to mention easy to install. Would recommend.

Rated 5 out of 5 by from Faucet has great features With Deltas long history of superior products and reliability wouldn’t purchase anything else. Specifically on the kitchen faucet i purchased it has a clean and sleek look as well as smooth action on the way the handles operate. Cant go wrong with purchasing any and all types of delta products.

Thick deck extension?

Is there a thick deck extension for this faucet? I can find a lot of other Delta faucet deck extension but none for this model. Will a extension kit for another model work? I only need to extend the hot and cold connections a small amount.
Asked by: Tim
Thank you for your inquiry, Tim! Delta does not manufacture a thick deck mounting kit for the Foundations Kitchen 21988LF faucet. This faucet requires a maximum deck thickness of 1 5/16" (33mm). Below, is the link for the technical specification sheet to show you the max deck thickness for the faucet. https://media.deltafaucet.com/SpecSheet/DSP-K-21987LF%20Rev%20F.pdf Best regards, Tanya

Why does it take a few seconds for the water to stop? The faucet is new.

Asked by: GiGi
Hi, GiGi! Thank you for your question. With our high arc faucets, the water does take a few seconds to drain out the excess water after shutting the water off. If the faucet leaks continuously after shutting off your water, please contact our customer service line so that we may help you further. Best Regards, Rosanna

I did not out the sprayer holder on.How do I remove the snap on connection to the water supply to put the sprayer hose through the holder?

Asked by: Ed
Reach up at the very top of the connection and squeeze the two tabs together and gently pull down on the hose. They only move about .05" inward, but it will release.

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

Can the faucet and handles be installed directly on the sink without the base?
