In your description for faucet 2256-RB-DST valve stem RP60400 is wrong. I have the same exact faucet as described but the part # for the valve assembly should be RP25513. I just received 2 of the wrong parts according to your diagram. RP60400 does not work on my 2256-RB-DST.
Thank you very much for this post Joe W.!!!
I bought a pair of RP60400 and these are the wrong stem for my Model#: 2256-RB-DST as well. Your post is over a year old and Delta is still pointing their customers towards the wrong part even though DeltaFaucet3 acknowledged it's not the right part for every model of this faucet in the post above, not sure why they wouldn't offer both so customers would know to do a little research to determine which stem unit is right for them. It's really not even difficult to tell which you have once you take one out, the RP60400 and RP25513 look quite a bit different.
I spoke with Delta customer service this evening and the rep told me he wouldn't be able to tell which stem I'd need because I couldn't tell him what kind of pipes I have coming out of the bottom of the faucet, I'd have to pull the sink or completely uninstall the faucet to see those little pipes that are up behind the sink; I am not doing that just to replace a stem.
So again, I thank you kindly for your post, I googled the RP25513 that you called attention to and it looks identical to what's in my faucet so I am confident that's what I need as well.
