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 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.

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

Our sprayer handle stick so it stays depressed after use. You have to wait a few minutes with the water running for the sprayer to release. Do you have any recommendations too free it up?

Asked by: Jared
Thank you for your question, Jared! A button sticking could result from mineral buildup inside the wand. This is usually addressed by removing teh wand and pouring a 50/50 solution of white vinegar/water through the wand. You may also let this soak in this mixture for up to 30 minutes if needed.
