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.

Handle screw/bolt part number for 21988LF faucet

My handle broke and I need the part number for the brass bolt with one end threaded and the other end splined with the chrome finish knob/end attached. I was able to get the threaded part out of the handle base so just need the bolt. It looks like part RP26852 which is 3.05 inches long and mine is more like 2.5 inches, end to end. Thanks Tim
Asked by: Tim
Hi Tim, Thank you for your question. The spindle and finial for the RP42995 handles on the model 21988LF faucet is not available as a separate item. The entire handle assembly would have to be replaced. Thanks, Dave

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

Asked by: Pickle
Dear Pickle, Thank you for you installation inquiry. The escutcheon/base plate of the Delta Foundations Kitchen 21988LF faucet is apart of the full faucet valve, it is not removable. Best regards, Tanya

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.

How come I can't buy a replacement spout for this faucet?

I tried to mount a PUR water filter on it using the correct adapter, but no matter how much plumber's tape I put on or how tight I tried to make it, the connection always leaked. I decided to remove it and just use the sink normally, but I damaged the end of the spout removing the adapter. I like the faucet and don't want to have to buy an entirely new one just for the spout as the spout is really well designed for a quick disconnect. It appears that no one sells the spout separately and I'm not sure why. Can I get a replacement spout from you? Thanks. J
Asked by: JFW
Hi JFW, Thank you for your question. Unfortunately the spout to the model 21988LF is not available as a replacement part. The entire faucet would have to be ordered. Thanks, Dave

Information left out

Why don't you print on your box that this is made out of plastic and not chrome? I was very upset when I found this out - after it had been installed.
Asked by: treetracker
Hi Treetracker, Thank you for your question. The model 21988LF is a metal faucet. The spout, handles, escutcheon base and valve body are metal. The side sprayer and mount are plastic components. Thanks, Dave

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
