Hi Joe, Thank you for your question. It sounds like you are reading instructions for the older faucets that use a ball assembly, seats, and springs. What you describe that you have is a RP50587 valve assembly to the newer DST faucets. If you have the newer faucet the entire cartridge can be removed and replaced.
If you need assistance with the repair please call our Help line at 1-800-345-3358.http://www.deltafaucet.com/repairpa...
