Rated 5 out of 5 by from Great Faucet Easy to install, my wife likes the spout sprayer feature and the ability to change streams to spray and back to stand flow by pushing a button. Happy wife, happy life...

Rated 1 out of 5 by from Great faucet... Until it leaks. Great faucet... Until it leaks. I had it installed a week ago and it looks and works great... for now. I was informed that there are no replacement parts for this. I checked the Delta wed site and sure enough NOTHING COMES UP. The "Repair Kit" RP44123 doesn't exist anywhere I looked. This is a Menards Exclusive and Menards doesn't have it. Multiple service people were unable to find it. I was told that since Delta doesn't list what the part numbers in the kit are, there is no way to order them individually. If I didn't have to pay to replace it I would return it. This is a VERY EXPENSIVE faucet for something that is basically DISPOSABLE.

Rated 4 out of 5 by from Easy installation! When our previous faucet unexpectedly failed (the head shot of onto the counter and water sprayed across our floor) we needed a quick replacement. We found it at Menard's and had it in place in a few hours. I really liked the ease of installation!

I need an adapter for this faucet that I can attach to the threaded nylon hose to covert to a 20mm or 26mm threaded opening.  I’m trying to attach an extension hose and I need this type of fitting.  Any recommendations?  Thanks!

Asked by: Joee
Hi, Joee! Thank you for your question. At this time, we do not make an adapter for the hose to connect an extension. Best Regards, Rosanna

what material is the pull-out hose...is it vinyl or spiral metallic chrome to match on the chrome model? Hose length is sorely lacking on many websites.... The length of the hose shows 59" in one spot...is that correct?

Asked by: Dukester
Thank you for your question, Dukester! The RP41122 braided nylon hose assembly that is used with this model, has a 59 inch length. Best Regards, Benjamin

How do you get the set screw loose in the handle

Asked by: Gayle
Hi Gayle, Thank you for your question. The set screw is located behind the red and blue indicator button. This usually requires either a 1/8" or 3/32" allen wrench. Best regards, Edward

Does the spray feature stay “on” when the faucet is turned off and back on again? Or does it default back to stream each time?

I like to use the spray feature exclusively when washing dishes, but like to only have the water running while actually rinsing so I turn the water off periodically. Will the spray feature stay on or will I have to push the button to get the spray back each time the water is turned off?
Asked by: Colleen
Hi, Colleen! Thank you for your question. The sprayer will stay on whichever setting you set it to. It will not change each time you turn the water off and on. Best Regards, Rosanna

My current faucet has a base with 2 handles. Does this come with a base that has just 1 hole for the faucet? If not, can a base be hold separately?

Asked by: pstallard
Thank you for your question pstallard! Model B4311LF-SD does include an optional escutcheon plate which has a single hole. This plate measures 13/16" (21 mm). Best regards, Edward
