Rated 4 out of 5 by from Poor Design Would not have purchased if we had known how difficult it is to replace/clean the aerator.

Rated 2 out of 5 by from the same problem as Disappointed I'm on a well, I cannot have a faucet that drips. I have been using Delta for over 40 years, and have never had an issue like this.

Rated 3 out of 5 by from Disappointed My wife received a replacement Delta Kitchen Faucet for a defective model. The new faucet is model 4380-AR-DST direct from Delta on April 17 2014. Over the last month we have noticed placement of the handle affects whether the faucet drips, runs on or actually shuts off. After reading installation paperwork I see I must purchase an entire valve assembly to fix the drip. I feel this product should have lasted longer than 4 and one half years.

Rated 5 out of 5 by from Replacement for a discontinued model We very happy with this faucet, it is very nice looking. We noticed it has better water pressure than the old model.

Rated 5 out of 5 by from Great features We're entirely pleased with the quality and features of this faucet set. We especially like the high arc of the faucet. The side sprayer works well and seems durable. It's not easy to find a side sprayer now, since pull-down sprayers have become more popular. This set meets our needs perfectly.

Rated 3 out of 5 by from Good color Searched everywhere to find replacement faucet for three holes in antique bronze. Works beautifully but very disappointed with the plastic piece covering the sprayer. Would have been so easy to make it bronze metal as well. Entire fixture now looks cheap

Is there a laminar flow faucet attachment compatable with this model? Or an adaptor that would work?

Asked by: Taylor
Thank you for your question, Taylor! Although we do not offer a laminar flow aerator for this model, this spout has a thread size of M21.5x1-6G. The RP51505 adapter will convert this size to a male 55/64”-27 thread. You may then be able to find a compatible laminar flow aerator locally or online. https://www.deltafaucet.com/parts-product-detail?modelNumber=RP51505 Best regards, Edward

I am considering purchasing this model of faucet but would like to know if the water supply can be mounted on the left, spout in the center and spray

Asked by: Rob
Our installer told us we could have the order be any way we wanted. We opted for as shown, but water supply on left would be good for lefties!

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?

Asked by: jean
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.
