Replacement works great!
The faucet started leaking just after 2 years of use. I called Delta and they sent me the new cartridge right away. I received it 3 days after my call.
The girl on the phone was very helpful and Delta sent it out at no cost to me.
Definately one of the easiest jobs on a faucet I've ever done! Ten times easier than having to deal with springs and seals that are used by most single handle kitchen faucets.
I read that there is a design flaw in the cartridge. But Delta is standing 100% behind their product. Don't know why there are so many negative reviews when Delta is willing to fix the problem.

2nd one to leak in 6 months time
This is my second faucet that leaks out of the handle. The first one home depot replaced and now i am having the same problem with a 6 month old faucet. I am not the least bit interested in paying a third of the price for a fix it kit on a 6 month old faucet.

Difficult to regulate water temperature
I have had the faucet for a couple of years and the valve assembly is so tight it is almost impossible to make small temperature adjustments to the water. The only way to adjust it is to lightly hit the handle until you get the desired temperature.

The RP50587 is a terrible product
I recently purchased this product because my two year old faucet began dripping and there was no way to stop it. My contractor reoiled the ring and it worked for a month. My replacement lasted less than 6 months and is now leaking again. If it fails so often, as other reviews indicate, why not supply the rubber ring as it likely is the problem...or is it? Time to replace with a different manufacturers product!

Beautiful Gaucet, but hard to shut off
I’ve had this faucet less than a year and the cartridge has malfunctioned. It now leaks and is almost impossible to turn off. The price of a new cartridge is almost half the price of the faucet.
We chose this faucet because of the quality behind the Delta brand. I expected better.

what is the switch on the top for ?
Thank you for your question, bill c! The switch on the top is a Handle Limit Stop, which allows you to either have the full range of motion for temperature control or to limit the handle from going to the hot side.
Best regards, Jon

When replacing part# RP50587, what is the best process for removing the bonnet nut? Is a special wrench required? Diffcult to tell where to loosen.
Hi Amber, Thank you for your question. The RP50587 can be removed using an adjustable wrench. The top of the bonnet nut will have the flat edges where the wrench is positioned. Here is a link to the How to replace the DST cartridge.

I have a 9178 delta kitchen faucet and the handle is becoming hard to move and squeaks. It appears that I need a Cartridge - DIAMOND™ Valve - 1H Model#: RP50587. Is this is correct, are there any special tools I need for this project?
Hi, Steve_H!
Thank you for your question, and I am sorry to hear that you are experiencing an issue with your Delta faucet. The correct valve cartridge assembly is RP50587. You will need a 1/8" allen wrench to remove the handle assembly. You may also need an adjustable wrench to loosen the bonnet nut around the valve cartridge assembly. Please be sure to turn off the water at the shut off valve before removing the handle.
Best Regards,
Rosanna

Is this the cartridge for the 955-DST? Also, is the cartridge the same quality wherever we purchase it? We would like to buy one and replace it today.
Hello Heather,
Thank you for your inquiry! Yes, the RP50587 is the correct cartridge assembly for the Delta Victorian Pull-Down Kitchen 955-DST faucet.
All Delta faucets and parts feature the same quality parts, materials, and workmanship, no matter what kind of dealer sells them. Delta retail dealers usually sell faucets that include the handles in the boxes. Plumbing professionals and Delta Studio Showrooms sell faucets where the faucets and handles are packaged and sold separately ("LHP" models), giving the customer some additional styling choices. However, the quality of all Delta faucets and parts are the same.
Best regards,
Tanya

I scratched the plastic piece below valve cartridge but cannot find the part number.
The piece I am trying to replace has three holes, sits below the valve cartridge, has three hoses connected to it, and sits on top of a brass ring. What is the part number for this piece? And how can I disconnect the three hoses from it to replace this piece?
Hi KJ, Thank you for your question. The puck assembly is not available as a replacement part. If the scratch is bad enough that the valve assembly will not seal onto the puck the faucet will have to be replaced.
Thanks,
Dave

My handle is leaking between the handle and the ball. Will the valve cartridge (RP50587) fix this problem
The water is coming out on top of the ball and going on the counter. If I order the valve Assembly, are the pipes that go to the hot and cold water supply and the pipe that goes to the faucet connected to the assembly. If they are , then do I have to cut them to length and attach proper fittings
Faucet is a Delta LeLand 978-DST
Hi, Gary!
Thank you for your question. If your faucet, 978-DST is leaking at the handle, we would recommend to try and tighten the bonnet nut at the cartridge. If this does not work, we do recommend to replace the cartridge, RP50587.
Best Regards,
Rosanna
