PRODUCT FEATURES
Convert your existing Delta® pull-down spray wand to one with Delta's innovative ShieldSpray® Technology. Delta ShieldSpray Technology cleans with laser-like precision while containing mess and splatter. A concentrated jet powers away stubborn messes while an innovative shield of water contains splatter and clears off the mess, so you can spend less time soaking, scrubbing and shirt swapping. Easy to switch out, simply unscrew the existing spray head and replace it with the new one. You can install with confidence, knowing that Delta parts are backed by our Lifetime Limited Warranty.

REVIEWS
Rated 3 out of 5 by from great customer service from support team this was a spray head, my water is extremely hard even with a high dollar whole house filtration system i get calcium buildup requiring maintaining the faucets/ outlets etc. this spray head is not serviceable so once it clogs up it is junk, the only positive is the warranty replacement( how many times???) unfortunately it is pretty much impossible to source the correct part on the web site so i went to a live customer service rep - who had many problems finding a spray head that would work though not identical

Is this head will fit "Marca"1978oz=spsd-dst-r faucet?

Asked by: tomek

My nozzle head will not switch form sprayer to regular spray. A11218M is the part number I am trying to replace.

Asked by: Gail
Hi Gail, Thank you for your question about the Delta Faucet RP90842. This is a replacement sprayer for faucet models 9183-DST & 9983-DST. A11218M is an engineering standard and is unfortunately not a part number. I recommend soaking the sprayer in a 50/50 mix of white vinegar and water. This can help remove mineral deposits that may be causing the issue. If the issue remains, the sprayer may need to be replaced. Please reach out for further assistance or with any additional questions! Best Regards, Bryan Digital Communications Specialist

There are a number of questions about cleaning this unit. Sprayer stops working (way too soon) with people with hard water (yes, we have a water softener), our only recourse is to buy a new sprayer $100 for a $200 faucet?
