Here is my attempt from a couple of years ago to understand the difference.

I Was Wondering...Spigot vs. Faucet
What is the difference between a spigot and a faucet?
In my last Thankful Sunday post, I said I was thankful for the cold water that came out of the faucet at the house I was visiting. Well, that's what I said, but not the first time I wrote it. The first time, I said that I was thankful for the cold water that came out of the spigot. I wasn't sure what to say, but I was tired and just chose one. Now that I have a little time, I thought I would figure out what was what.
And once again, I'm confused because they are synonyms of each other. Both spigot and faucet refer to atap (another synonym) or a valve that controls the flow of liquid into something. You can have a tap in anything from a cask to a water pipe. I never thought about it, but that is where the phrase "tap water" comes from that refers to water coming straight from the faucet/spigot/tap.
However, there are some US regional variations in usage. In the south, spigot is more commonly used while faucet is more commonly used in the north. Also, some use spigot to mean a tap outside and one that is more utilitarian while faucet is used for a tap inside that is fancier.
So there you have it. Use either one you want and you will be okay. After all of this talk about water, I'm thirsty. I'm going to have a drink of tap water from the faucet after I wash my hands from the spigot in the bathroom. :)
What word do you use, and do you use different words for a tap in different situations?
