I have a pretty old delta faucet in my kitchen that is about 10+ years old, it looks like https://www.homedepot.com/p/Delta-F...ide-Sprayer-in-Stainless-B4410LF-SS/203426262. There was leaking issues with the sink so I was planning on replacing the O-rings and knob handle. However, I can't pull off the spout (neck). I've put some lubricant and knocked on it with a rubber mallet to no avail. I don't know what to do next because I've used almost full strength trying to rip it out. Any suggestions and advice would be appreciated.
