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

Hi, Joseph! Thank you for your question. To replace the Delta RP50587 valve cartridge assembly, first turn the water supply off at your faucet. Unscrew the set screw of the handle with either a 1/8" or 3/32" allen wrench, depending on your faucet model number. Once the set screw is removed from the handle, the handle can be removed. Unscrew the cap and bonnet nut counterclockwise. Once this is done, the cartridge can be pulled up by the stem of the cartridge. Clean cartridge or reinstall new cartridge as needed. Best Regards, Rosanna

Thank you for your question, UKKC! The RP50587 valve assembly is the correct cartridge for a Delta 19922-SSSD-DST kitchen faucet. Best Regards, Benjamin

Hi, Jack! Thank you for your question. Unfortunately, we do not have a break down of the cartridge as the cartridge itself should not be broken down. If the valve cartridge assembly is in pieces, we recommend to replace the whole part. Best Regards, Rosanna

Hi there Mikeasmel, Thank you for your inquiry! Yes, the RP50587 Valve cartridge assembly would be the right part for your Delta Addison Pul-Down Kitchen 9192-DST faucet. Please see the below "How To Video" for replacement instructions. https://www.deltafaucet.com/video-gallery/video-page?videoId=1KMlxNiWni8 Best regards, Tanya

Hi, Confused in WI! Thank you for your question. The orange switch on the Delta RP50587 Valve Cartridge Assembly is a handle limit stop which is an optional safety feature that can be used to prevent the handle from moving too far to the hot side. Best Regards, Rosanna

Thank you for your question, Rejeanne! When changing a stem unit or cartridge assembly, it is always recommended to ensure the water is shut off completely to the unit. You will then need to remove the handle with either a 1/8" or 3/32" allen wrench. The sleeve and bonnet nut can be removed to reveal the cartridge which will pull straight out. Inspect the valve body for buildup or debris, then re-install the new cartridge, taking note of the tab or tabs located on the bottom for proper alignment. Best regards, Edward

Hi Fred, Thank you for your question. Unfortunately the gasket to the RP50587 valve cartridge is not available to order as a separate item. The entire cartridge will have to be replaced. Thanks, Dave

Hi, Sparkysmom030906! Thank you for your question. The Delta RP50587 Valve Cartridge Assembly does not fit the 9959T-DST Faucet. For 9959T-DST models produced before 01/01/2018 the correct cartridge is RP60114. For 9959T-DST models produced after 01/01/2018 the correct cartridge is RP73000. Best Regards, Rosanna

I have this same issue. I need help as well.

Thank you for your question. Delta Faucet model RP50587 is for the newer 468-DST models. What you have is an older model 468, and the peice you need is an RP70 ball assembly. It is a different kind of stem assembly.

Hi, Dddd! Thank you for your question. The label indicates that components inside the product contain exposed brass, which includes small but detectible amounts of lead—an element on the Prop 65 chemical list. Many products sold in California are required to carry this label. Even though a product may be found to contain a Proposition 65-listed chemical, it does not mean that use of the product will cause cancer, birth defects or other reproductive harm. Nor does it mean that a product is unsafe. All Delta Faucet Company products meet or exceed the requirements of applicable product performance and safety industry standards, as well as the federal Safe Drinking Water Act. We are confident there is no health hazard associated with the installation or removal of our products. Best Regards, Rosanna

Hi, Teresa! Thank you for your question. Depending on your faucet model, the allen wrench size would either be a 1/8" or 3/32" to remove the set screw to get to the valve cartridge assembly. Best Regards, Rosanna

Flushing the faucet solved my problem. I removed the screen from the end of the faucet (where the water comes out). Mine was clogged with lots of tiny bits of rubber. Once I washed that all away, flow was back to normal.

Thank you for your question, Big Ronnie! The Delta RP50587 cartridge can be replaced by first shutting both the hot and cold water supplies completely off. Put the handle in the "On" position to drain any remaining water. Then loosen the set screw, remove the handle and unscrew the cap and bonnet. Check for debris in the valve body and then insert the cartridge and ensure it is seated properly. Then tighten the bonnet hand-tight plus a 1/4 turn with a wrench. Please contact us directly if you have questions and we would be happy to walk you through this process. Best regards, Edward

Hi, Yossel! Thank you for your question. The Delta RP50587 valve cartridge assembly can be installed by first turning the water off at the shut off supply.

Thank you for your question, Bill! The switch is a Handle Limit Stop which can be switched to the right in to prevent full hot water. Please refer to the Installation Instructions for more information: https://media.deltafaucet.com/MandI/64211%20Rev%20A.pdf Best regards, Jon
