Rated 1 out of 5 by from Warning: Low-flow Design The cartridge failed after <2 years, which to Delta's credit was replaced under warranty. However, we were sick of the low flow from this faucet, and I finally attempted to pull out the flow restrictor at the nozzle only to find that it's integral to the faucet, so not it's ruined and have find a better faucet. Also, this faucet uses some oddball oversized rosette washers (the "nuts" that secure the faucet body to the sink) that seemingly aren't available anywhere; why, I have no idea.

Rated 1 out of 5 by from Poor quality Bought couple years ago, replaced/upgraded water lines in house and after doing that the faucet and sprayer where not putting out pressure like before. I even tried to replace the ceramic cartridge and it wasn’t that

Rated 1 out of 5 by from Not what I would expect from Delta Our kitchen faucet was less than a year old when we purchased our house in October 2018 and has dripped ever since we moved in. I would expect better quality from Delta!

Rated 5 out of 5 by from simple elegance I just wanted a simple, basic faucet for my kitchen and this fit the bill.

Rated 5 out of 5 by from LOOKS GREAT I bought this at Ace Hardware and it more than met my expectations. The sprayer has a rugged handle that should last longer than the cheaper plastic units.

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

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

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

whats the difference between Classic and the Collins. I do know which style I have .

I need to purchase the sprayer head and hose.need to find out what one I have. Thank -you some one else installed this.
Asked by: chrissy
Hi, Chrissy! Thank you for your question. The difference between the two units is the style of the faucets. The Classic has a straighter handle while the Collins will have a bit curvier handle and a slightly curvier spout . Best Regards, Rosanna

How to replace sprayer?

How do I replace the spray nozzle
Asked by: Tom
Hi Tom, Thank you for your question! To replace the sprayer itself you can unscrew the sprayer from the hose and attach the new one. To replace the complete hose and sprayer assembly, pull the blue clip out from the gray housing where the sprayer hose connects under the sink. You can then pull down on the hose to remove it and then pull the sprayer and hose out from above the sink. Install the hose and sprayer in the reverse order and pull down on the hose to ensure that it is properly attached. Best regards, Jon
