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.

Rated 3 out of 5 by from Sprayer started leaking after 3 days Sprayer started leaking after using cold water through the spout. Spout also seems rather loose where it threads into the base. Faucet is also very light weight and I'm not sure how long it will last.

Rated 5 out of 5 by from install, appearance, quality of material, simple We purchased this a week ago from our local Home Depot. Exactly as advertised. Our handyman suggested Delta. This replaced a previous Delta faucet, and we like it a lot.

Howdy, 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? Much obliged, Matt

Asked by: tomhorn1913
(Foundations 21988LF) -The spout and handles are NOT internally metal, but instead plastic. This was confirmed to me by a Delta phone representative.

What kind of adapter would I need to attach a portable dishwasher hose? it's to small for the tip and when I unscrew it it's too big. can't seem to find the right size. Any help is appreciated

Asked by: theopholismmviii
Hello, Theopholismmviii! Thank you for your question. The Delta Foundations Kitchen 21988LF-SS faucet has an aerator with a thread size of 55/64"-27. You will need to talk to your local retailer or wholesaler about getting an adapter that fits your portable dishwasher to also fit the faucet thread size. We do not manufacture any adapters for attaching dishwashers or filters. Best regards, Tanya
