Q&A
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.

I was sent a replacement sprayer & hose assembly. My old sprayer has a square white disconnect-replacement has round disconnect with 2 small black washers&blue plastic piece.video that shows how to convert would help-answer y’all provided b4 doesn’t help
I also received a replacement sprayer & hose assembly with no instructions. The old sprayer hose assembly had a white disconnect piece on the attachment nipple that needs to be removed. Then the new blue piece will need to be replaced. Make sure that the arrow on the blue piece is pointing down. After this small blue piece is installed, you can attach the new sprayer & hose assembly.

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.
