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
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.

can this faucet be installed without the sprayer
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.

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?
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?
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.

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.
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.

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.
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.

How do I disconnect the sprayer so I can reroute the hose?
Thank you for your question. The Delta 21988LF Faucet sprayer hose can be removed by pushing in the two tabs at the connection, much like a clothespin. Once pushed in, push up at the connection. This will release the hose from the valve end. The hose can now be pulled down and removed.

Hello! I had Model 21988LF installed today. It looks great! But when I turn the handles on, there is a brief 'clunk' sound. Maybe even a little bit of a shake (like a quick jerk, as the water begins to flow). Any ideas what is going on? Thanks!

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