Hi G,

With your faucet being purchased in 2005, you are correct in that his faucet will not take the RP50587 cartridge. You will want to replace the RP3614 repair kit as well as the RP70 ball assembly.

Also, please flush the lines before installing the new parts. To do this, once you have removed all the parts from under the handle with the water turned off, please will place a bucket upside down over the faucet, get a good hold on that bucket and turn the water back on. Let the water run for 30-45 seconds, turn the water back off and install the new parts.

If you have any questions or would like further instruction, please contact our warranty line (1-800-345-3358).

Thank you for your question. I apologize for the issue that you are experiencing. We do not recommend taking apart your cartridge. There are not separate parts available for the cartridge. To ensure the proper part is identified for repair, please contact our toll-free Home Owner/Warranty department at 800-345-3358.

Thank you for your question. Delta Faucet model # RP50587 is a cartridge that is used in many of our faucets. It will depend on which faucet it is used in as to how to replace it but usually the water is turned off and the handle is then removed. There is a bonnet nut underneath that is removed and then the cartridge is taken out. The new cartridge can then be put in making sure that you match the notches in the body of the faucet. Each part is then replaced in the same order it was taken out.

You may also contact our Home Owner/Warranty line at 800-345-3358 and they will walk you through the instructions while you are on the phone.

Thank you for your question. I apologize that you are having trouble adjusting your temperature. We recommend turning the volume on at full power and then getting the temperature you would like. Once that is done, leave the faucet on and it will always go to that temperature.

Thank you for your question. Delta Faucet model # 955-SS-DST does have a ceramic disc cartridge. There are also non-metallic parts to the cartridge, and this is a normal industry standard for ceramic disc cartridges.

Thank you for your question. I apologize for the issue that you are experiencing. The little orange switch does not affect how your faucet turns on and off. This switch regulates the temperature of your water and can be moved to turn down the temperture of the water. You may need a new cartridge.
