They talked at me and talked until I got water on the ear.
I've never heard that expression. It almost sounds like it's been translated from another language. Here are some English idioms that can be used if someone is talking too much:
That guy talked my ear off.
That guy kept talking, but I finally tuned out and started daydreaming.
That guy was a motor mouth and wouldn't shut up!
After a while, all I saw was his chin wagging while I thought about something else.
