Q&A
MY RP54807 spray / hose assembly is leaking at the base of the nozzle handle. Is there was way to remove the hose and reinstall it? If not the replacement seems to be a RP103754OB. Is this correct? Oil rubbed bronze is the finish.
Hi Anonymous,
Thank you for your question and we are happy to help. Installation instructions for the Foundations can be found in the link below:

Will the RP103754SS replace the RP54807? Do the quick connect fittings match and are they interchangeable? I have a Model 21996LF series / S/N 413763-A faucet.
After some back and forth with support, the RP103754SS will replace the RP54807 *IF* you get the RP103673 plug replacement kit. That will swap out the square connector for the newer round connector. Why this isn't more commonly known with the support teams seems to be a massive support ($$) loss for Delta on resending connections.

Hello Valued Customer,
Thank you for contacting Delta Faucet Company!
To connect the sprayer, please refer to page 3 box 1B in the link below! The parts in the bag are for the connection you have for the sprayer. The link below will show a photo and explain how these are installed.

I have a builders grade chrome faucet with a side sprayer. The part on the sprayer that is pushed to start spraying is broken. The head and neck unscrews from the bottom that is connected to the hose. Can you send me that part?

Where can I buy a replacement hose assembly #RP103754? I have not been able to find a replacement and the hose has cracked. None of the “universal “ kits have the correct faucet fitting. This has been a great unit.
Hi Greg,
Thank you for your question about the Delta Faucet RP103754 replacement sprayer and hose. Please accept our apology for the inconvenience you are experiencing with the hose. We are happy to help!
We no longer make the hoses with a square white quick-connect. The recommended replacement is this RP103754. Which now has a round quick-connect. You will need to use the entire kit to also change the block and o-rings on the faucet nipple so that the round quick-connect can be used.
Please reach out with any additional questions!
Best Regards,
Bryan

The button of my sprayer is slow to respond and gets stuck. How can I make the button responsive again?
Hello Customer!
Thank you for your question and we are happy to help. We recommend scrubbing the face of the sprayer as well as soaking it in 50% warm water and 50% white vinegar to break up any debris. If this does not resolve your issue, please contact us directly by giving us a call or sending us an email.
Best Regards,
Carrie
