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.

Rated 4 out of 5 by from Solid and functional This is a great faucet, tight design and feel. Not fabulous, but it doesn’t need to be. It’s a workhorse.

Q&A

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
