Works OK
Cartridge installed easily & works. Seems to have lower water pressure coming out the faucet now. Not sure if there's a way to fix that...

Q&A
what does the red button do? How is it to be set?
Hi, Nao!
Thank you for your question. The button on top of the cartridge is a handle limit stop. This faucet includes an integrated handle limit stop that has two positions.
When you position the button to the left, this position allows full handle motion (the full range between “all cold” to “all hot”). The faucet is set in this position in the factory. When you position the button to the right, this position allows half of the normal handle motion (“all cold” to “mixed hot/cold”).
The handle limit stop can be adjusted by the homeowner once the faucet
is installed. Setting the handle limit stop in the second position may help to prevent scalding because it limits the amount of hot water in the mix.
To change positions of the handle limit stop: remove the handle;
move the valve stem to the all cold position so the water is on; change
the position of the handle limit stop; turn off the water; reinstall
the handle.
Best Regards,
Rosanna

I have an Older Delta model Faucet, pull down, 3 years old maybe. Is this cartridge universal?
Thank you for your question, Techman23! While the RP50587 cartridge is compatible with several Single Handle Delta Kitchen Faucets manufactured after 2010, it is not a universal cartridge. Some newer Delta single handle kitchen faucets take an RP60114 cartridge, and some take an RP73000 cartridge. Some single handle faucets have a ball assembly with seats and springs, instead of a cartridge.The part number for the cartridge can be found in the Parts Diagram, under the Documents & Specs tab on the faucet's web page. Feel free to contact us directly, if you need further assistance.
Best Regards, Benjamin

How can I find a RP50587 cartridge assembly Diagram?
Hello Roget,
Thank you for your question. The Delta Valve cartridge RP50587 is not designed to come apart, so we do not have a parts diagram of this part.
