Are replacement kitchen sprayers fairly interchangeable?
For the most part hardware stores will carry universal side sprayers, that can be used to replace broken sprayers from nearly all manufacturers.  You might come across a proprietary side sprayer from time to time, but chances are a universal replacement will work.  You may not find a sprayer that matches the look and design of the broken sprayer exactly, but a replacement should attach and function without problems.

Keep in mind, this only applies to side sprays.



If you break the pull down sprayer, you'll likely have to get a replacement from the manufacturer.
