I've had a sprayer faucet in my kitchen sink since I bought the house over 8 years ago. Somewhat recently it sprung a little leak on the right side. Today I noticed that this leak has expanded from one little jet of water to three, so clearly it's getting worse. I'm not sure what the best method to deal with this is - will I need to just replace the whole sprayer? Or is there some sort of sealant or other substance I can patch on there? I have photos attached.
And here's an animated version too.
