Rated 5 out of 5 by from Looks Great After deciding it was time for a mid-range upgrade to my kitchen faucet this item turned out to be the perfect choice. Easy install, attractive yet functional, and the cost was in line with other faucets.

Rated 3 out of 5 by from Not sure yet Installation a snap & that's NOT a good thing. Where the sprayer "snaps" together it leaked & no way to take it apart or tighten - it only snaps/poor design in my opinion. Delta is sending new part, but I had to take photos & put them through Adobe to get them the right size, etc. to send - a pain/wouldn't take my word for it even though I sent them the parts # needed in initial e-mail. We'll see if the replacement part leaks too.

I am trying to install a Brita Water Filter to the faucet. How do I remove the aerator and get connector?

I do not have the wrench that came with the assemble since I just moved into this house. I want to install a Brita water filter, but it does not look like any of the connectors will fit and I do not know how to get the aerator out. Can I just pop it out with a screwdriver?
Asked by: Ticked
Thank you for your question. Delta Faucet model # 21902LF-SS has a cache aerator that needs a wrench to remove it. The part number for the wrench is RP46858 and can be ordered and purchased from your local wholesaler or retailer. There is also an adapter that can be purchased to convert your cache aerator to a 55/64"-27 male thread. That part number is Delta Faucet model # RP51505.

adapter for PUR filter

recently purchased and installed this great faucet - thank you! Now, I need to attach a PUR filter to it - none of PUR's standard adapaters work with this faucet :(. Please provide thread specifications for the faucet so i can special order an adapter or perhaps Delta makes adapters for faucets with non-standard threads??? thank you!
Asked by: YG
Hi YG, Thank you for your question. You will need to remove the aerator from your model 21902LF-SS faucet and install the RP51505 cache aerator adapter. This adapter will convert the metric threads on the faucet to a standard 55/64″-27 male thread. This standard thread pattern should work with the Pur filter. http://www.deltafaucet.com/repairparts/details/rp51505.html Thanks, Dave

How are the handles removed ?

Asked by: Verne'
Hi Verne! Thank you for your question. To remove the handle on Delta model 21902LF-SS, please use a 3/38" Allen wrench to remove the set screw on the side of each handle. Once these set screws are removed the handles will pull up and off. Best Regards, Courtney

can I install this faucet directly on my quartz countertop without the escutcheon plate

Asked by: kathy
Thank you for your question. Delta Faucet model # 21902LF-SS requires 4 holes for installation and the escutcheon plate for a complete faucet.

Where can I get the Delta aerator thread size 21.5x1-6G so that I can use my Pur filter?

You need to either supply Pur with the info they could use to make an adapter to fit this faucet, or change the threads in it so that it will work. I won't keep the faucet if I can't use the Pur with it. Very disappointed. Wish the box would have said that it can't accommodate the Pur.
Asked by: LB
Thank you for your post. Delta Faucet model # 21902LF-SS does come with an aerator with a thread size of 21.5 X1-6G, and if you take that information to your local retailer or wholesaler, they should be able to provide you with an adapter. Delta Faucet does not manufacture one for this model.

Does this show water spots & fingerprints?

Asked by: Cher
Hi, Cher! Thank you for your question. The 21902LF-SS Faucet in the Brilliance Stainless Steel finish is not water spot and fingerprint resistant. We recommend to wipe clean with a soft cloth after use. Although our finishes are extremely durable, they may be damaged by harsh abrasives or polish. To clean, we recommend simply wiping with a gentle damp cloth and then blotting dry with a soft towel. If water deposits are especially troublesome, you may use a 50/50 mixture of white vinegar and water to remove them. White vinegar is strong enough to dissolve mineral deposits, yet mild enough not to damage our finishes. Note: Please be aware white vinegar may stain some porous materials like untreated stone. If you have an unsealed tile or counter top, please take care when cleaning your products. If you’d prefer using a chemical cleaning product, our finishes may be cleaned with the following household cleaners: Formula 409® Antibacterial All-Purpose Cleaner, Fantastic® All-Purpose Cleaner, or Windex® Original Glass Cleaner, when used according to the manufacturer’ instructions. Any cleaners not listed above may be tried if they do not contain hydrofluoric, hydrochloric and/or phosphoric acids or similar caustic agents. Some examples of chemical cleaners to avoid are: green Scotch-Brite Heavy Duty Scrub Sponges, Scrubbing Bubbles Bathroom Cleaner and Lysol Basin Tub, and Soft Scrub and Tile Cleaner. Note: Any products that state on the label that they remove tarnish and rust will most likely harm the finished products. Most drain cleaners may be used when following their specific directions and not allowing exposure to the finish longer than 30 minutes. Best Regards, Rosanna

Is there a swivel aerator available for my faucet?

Model 21902LF-SS Internal THDS. not a standard thread
Asked by: Rich
Hi Rich, Thank you for your question. Although you cannot screw a swivel aerator into your model 21902LF-SS faucet there is an adapter available. RP51505 will screw into the faucet and give you 55/64-27 male threads which will give you a platform for a swivel aerator. Thanks, Dave
