Reviews

Rated 4.1 out of 5 by 20 reviewers.
Rated 5 out of 5 by Excellent features The installation was a snap and the underneath attachments are far superior to prior designs. Also like the snap in water attachments for the sprayer and the spout and the water inlets are flexible and much longer. The spout is higher and extends out further than past models. The only thing we had to get use to was the front handle sprayer vs the old rear handle design. July 10, 2013
Rated 5 out of 5 by looks great and feels great i have no problem with the faucet.. in addition the sprayer feels heavy in your hand and the finish is easy to clean.. love it and if it lasts as long as my last waterfall delta i will be happy..it was very easy to install..i wish the soap/lotion dispenser was included instead of having to pay extra.. June 12, 2012
Rated 3 out of 5 by Sprayer Leaks , water lines are plastic. the water lines are plastic, an too stiff, your sprayer attaches to them over 12 in down, an that takes away on how far out you can pull the sprayer out. the sprayer has a leak after you use it, it leaks out of the nozzle head. November 23, 2014
Rated 5 out of 5 by We shopped a long time We have always preferred Delta faucets. We are very pleased with our new one. We have had it now for one year and it is just like new. We love it. June 12, 2012
Rated 5 out of 5 by This product has a finish that is simply dazzeling This product is a total re-invention of the sink faucet. If you have not looked at Delta lately, you missed it! April 30, 2013
Rated 5 out of 5 by Clean lines, very functional This was a replacement for a previous Delta faucet that had begun to leak. We called customer service and were told the faucet could not be repaired and were immediately asked about requirements for a replacement, given the options that worked and shipped this new one. We were also offered 50% discount if we chose to replace the bar sink faucet that matched the old sink. My only complaint is we were not able to find a pull down sprayer we liked and so had to get rid of the old soap dispenser. Delta did plan to replace the soap dispenser to match the new faucet, if we had chosen that option. It coordinates well with the bar sink faucet and does what its supposed to do! I like that it swivels to the left out of the way of the sink. November 8, 2013
Rated 5 out of 5 by Nice design, works well This faucet works very well and the design is pleasing to the eye. June 29, 2013
Rated 2 out of 5 by BEAUTIFUL & FUNCTIONAL, BUT... I did a kitchen remodel in August, 2011. I selected this beautiful faucet set, along with the soap dispenser. This past Saturday, I noticed a nasty leak under my sink. The plumber came within two hours and said the whole assembly, excepting the soap dispenser, had to be replaced. I was absolutely stunned! The last faucet (not same brand) lasted for close to twenty years and had much heavier use than this one. I am so disappointed! Maybe I just got a lemon? At this point, I'm going to contact Delta CS and see what they will do. May 3, 2016

Hi Mike, Thank you for your question!
The RP63039 .5 gpm aerator can be used with the 4380-DST single handle kitchen faucet. Both the original aerator part number RP52216 and the RP63039 have the same thread size of M21.5x1 Male threads.

Yes, the spout swivels. I can move it completely out of the way for large pots, sink cleaning, etc.
This is a lovely grouping, but mine just sprung a nasty leak that warped my fairly new cabinet floor after only six years of use! Maybe I got a lemon, but regardless, the plumber said I need a complete new assembly.

Hi JC, Thank you for your question!
The handles are different on the 4380-DST ( Non Touch) and 4380T-DST ( Touch version) but the handles will interchange. You would have to order the handle you are interested in separately. Below are links to the parts diagrams of both models:

Hi Bob, Thank you for your question!
The water should stop from the main spout while running the sprayer. If it continues the run the diverter needs to be replace. The diverter is apart of the sprayer assembly part number RP53880AR.

Which aerator adapter for DST-4380?

Purchased DST-4380 June 2015. I just purchased the RP51505 adapter but it does not fit into the faucet. The bottom threads on the RP51505 do fit the aerator I would like to use. Is there an adapter that fits the DST-4380 with same size bottom threads as the RP51505?

Why does the RP53998 arator diameter smaller than the end of the faucet?

We have ordered 2 areators but they are both too small to screw into the end of the faucet. Is there anything that goes into it to make it fit.

Hi Danny, Thank you for your question. There was a running change on the aerator for the model 4380-AR-DST that changed the thread pattern on the aerator from a metric M21.5x1-6g to a 13/16". The RP70718 is the replacement part for the aerator that will fit your faucet.

When I turn my faucet on the water splashes back all over the sink my clothes and the floor. Is there any way this can be controlled?

Answers

Answer: 
Thank you for your question. Delta Faucet model # 4380-SS-DST flows at 1.8 gpm at 60 psi. You can make your faucet flow at a lower rate by replacing the aerator. We have a .5 gpm with model number RP71111 and 1.0 gpm with model number RP72730.

By lowering the gpm on your faucet, it may help with splashing. Otherwise, we can recommend not to turn the faucet on to its full force if it is mounted on a smaller sink.
