Rated 5 out of 5 by from Looks good, installs easy and great warranty. I purchased the Model 21988LF over a month ago and replaced a NON Delta faucet that was on a deep sink in the utility room. It was a washer type and over thirty-three years old. I replaced many washers during those thirty-three years and one valve seat. The cold water supply to the old faucet broke one day and WHEN DID IT? You guessed it, when I wasn't home. Water was everywhere when I returned. I recently read the one and two star reviews about the flimsiness of the 21988LF faucet handles. People stated that they flex when turned off. Folks these are washer-less faucets and are made to be turned off and on with one or two fingers. Yes during the "good ole days" the washer type faucets offered more resistance to movement and at times you really had to crank down on them to stop a drip. When that happened it was time to replace the washer but most people didn't and continued to apply more twisting force to obtain a complete drip stop. As I stated earlier, washer-less faucets are manufactured to be turned on and off with very little resistance so all the extra seals, brass and steel aren't necessary to make a good product. All of the remaining faucets in my house are washer-less. All but three are Delta and that is another story as to why they are another brand. I have replaced washer-less components in the three that aren't Delta five times since they were installed. In over thirty-three years not one of the Delta faucets has ever leaked. If one of the Delta faucets starts leaking I know I will be able to purchase a replacement part instead of a new faucet. Over forty-five years ago a plumber told me to by only Delta and if something malfunctioned I would either be able to find a part to fix the problem or Delta would replace it. So far not one Delta faucet is dripping or spewing.

Rated 5 out of 5 by from Best faucet I’ve ever bought I bought this faucet less than a month ago and I just love it. The handles are easy to turn, I love how it looks on my sink and overall it is the best faucet I’ve ever bought

Rated 5 out of 5 by from Easy to install! I like it because it does NOT have Ceramic cartridges and the cost of replacing bad cartridges is Much more reasonable!

Rated 5 out of 5 by from Beautiful I bought this a couple of years ago, and the sprayer started leaking almost immediately. Delta replaced it, without question, even more than a year later. The service was great and the replacement arrived within days. The new sprayer, so far, works great, with no leaks. This set looks great. I just wanted something different than chrome.

Rated 5 out of 5 by from Works really well. My plumber bought this and installed it last week. I am enjoying it, especially the sprayer.

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

Model: 21988LF - What Mounted Water Filters will fit?

I just replace my older Delta Kitchen Faucet with the 21988LF and the adjustable Mounted Water Filter does not fit this new Model. What companies make a Filter the will fit, and what Size should I look for when I go do purchase one? Thanks very much Riah
Asked by: Riah
Thank you for your question. Delta Faucet model # 21988LF has an aerator with a thread size of 55/64"-27. We do not have any filters to recommend but you will need the thread size above to make sure that it fits properly.
