I recently replaced the normal head of the faucet with one of those that you can change from one to the other. Sometimes I want the stream for filling water bottles, etc. Then sometimes I want the sprayer to clean the sink. But I don't want the sprayer when I want to fill a bottle and I too often forget which setting it's on.
So tonight, I got out my trusty dusty marker and made a little "guide" to let me know which is which for the little lever.
