Rated 4 out of 5 by from Save the Diverter Plug! I bought this kitchen faucet in 2013--thirteen years ago--and it performed well until two days ago, when I felt water on my foot while using the sprayer. The sprayer hose cracked in a few places near the diverter valve where the hose bends the most when used, and it did an impressive job of spraying everything in the cabinet below the sink when it finally let go. There was enough water coming out of the split hose that it ran out of the cabinet and onto my foot to let me know it failed. I called Delta, and they are sending me a new diverter/sprayer hose for free since the failure falls under their lifetime warranty. I probably use the sprayer an average of a few times a week, to give you some perspective on the longevity of the hose. From what I've seen in other reviews of this faucet, the diverter/sprayer hose is a common point of failure. The important take-home that prompted me to write this review is that the faucet comes with a "diverter plug" installed in the fitting for the diverter/sprayer hose, so there is the option of using the faucet either with or without the sprayer hose. The installation instructions I received told me to discard the diverter plug if I was installing the sprayer hose. Don't discard the diverter plug! Saving the diverter plug and installing it after the diverter/sprayer hose failed allowed me to continue using the faucet without the sprayer. It made the difference between having no running water in the kitchen while I wait for the parts from Delta to arrive, and having running water in the kitchen. Do I wish the sprayer hose had lasted longer than 13 years? Of course, but since the diverter plug saves me from going without water in the kitchen while I wait for the free replacement from Delta, I'm okay with it.

Rated 3 out of 5 by from Not was it once was. Have used this faucet for decades but the recent one purchased on12-30-25 has been a disappointment. The sprayer will not cut off half the time. Luckily I had not thrown away the old ragged looking one and I'm currently using it. Apparently the sprayer relies on water pressure to help shut it off. If any water is being used anywhere in the house the sprayer will not shut off properly!

Rated 2 out of 5 by from Terrible sprayer The side sprayer needs a total re-design. Already have had to replace and still does not work properly and leaks.

Rated 3 out of 5 by from Average Faucet drips after turned off. Especially if you don’t put the handle in the right spot.

Rated 5 out of 5 by from Looking good! Easy to install ( it took fore time taking out the old one ) and operate; a little less flow, but that I believe is the new standard. I even looks better than the old Danze thing that I was about to repair for the fourth time in 3 years. Using a pex style install was new to me as well, but it's easier than copper.

Q&A

can you install the faucet without the base plate?

Asked by: bdub
Hi bdub, Thank you for your question. The base plate cannot be removed. However, the model 441-SS-DST is very similar to this unit and does not have a base plate. http://www.deltafaucet.com/kitchen/details/441-ss-dst.html Best regards, Jon

Recently had the Classic 400-SS-DST installed with a new sink. Is there any way to increase the water pressure in the sprayer. It's just a very soft spray and my older model had more force which I liked better and did a better job spraying off dishes.

Asked by: Cath70
The sprayer came with the faucet so both are brand new, which clogging wouldn't be a problem. I thought maybe it had some type of water saving part inside that could maybe be removed that would help but couldn't find this out in the paperwork that came with it. I really like the faucet but the sprayer is frustrating with such a low spay power.

Is there a way to disable the sprayer hose for this faucet? 

Asked by: Nancy
Hi, Nancy! Thank you for your question. The Delta 400-DST Faucet can be used without the sprayer assembly. To use the faucet without the hose attached, you will want to cap the end valve with the cap, part number RP54269. Here is a link to this part: https://www.deltafaucet.com/parts-product-detail?modelNumber=RP54269 Best Regards, Rosanna

how do I install it,your instructions are confusing

Asked by: diy always
Dear Diy Always, Thank you for your question. To install the Delta Classic Kitchen 400-DST faucet. You would first remove the old faucet. Remove the gasket from the old faucet and install it onto bottom of the new faucet. Next, feed tubes/shanks down through mounting hole in the sink. Secure faucet to sink with mounting nuts supplied with your faucet. Mount the spray support in far right hole of the sink. Hand tighten the mounting nut. Insert sprayer and hose down through support assembly. Please see diagrams in the Below Maintenance/Installation document below. https://media.deltafaucet.com/MandI/75106%20Rev%20B.pdf Best regards, Tanya

What is the thread size for the aerator?  Better to chose a different design if used with portable dishwasher?  Thanks

Asked by: Dwildemn
Hello Dwidemn, Thank you for your question regarding the Delta Classic Kitchen 400-DST faucet. This unit comes with a 5/16"-27 Male thread aerator. A portable dishwasher may be used with this model. However, it is up to the installer to adapt it and ensure a leak-free connection. Because the spout has an internal tube, water could leak below the sink. You may use the gasket from the aerator with the necessary adapter, but an additional gasket may be needed. Best regards, Tanya

Can I convert the DST 400 from an existing 3 hole installation to a 1 hole installation?

Faucet with cover plate covers 3 holes and sprayer uses 4th hole. I bought a water filtration system and need one of the 2 covered/unused holes for installation. I would like to re-use the existing faucet instead of buying a new one. I saw you sell RP51490. Can I buy this and just exchange it with the current 3 hole plate?
Asked by: tvirtualw
Hi tvirtualw, Thank you for your question. Unfortunately the escutceon plate on the model 400-DST cannot be removed and switched out to another escutcheon. We offer the 2 hole install 175-DST and the 3 hole install 300-DST faucets from the same Classic collection that would free up the extra hole. Thanks, Dave
