Strange Part in a Strange Place

A few days ago our hot water just quit flowing from all faucets in our Itasca Class C motorhome. The cold water flow was just fine and the water pump sounded normal.

After scratching my head over and over I began taking things apart, starting with the outlet fitting on our 6 gallon hot water heater.

Wedged perfectly right in the outlet fitting of the hot water heater - with the flat disc facing me and the stem facing inside - was this part. Do any of you have an idea what this part came from in the motorhome's fresh water system and how it could get inside the hot water tank and wedge itself in it's outlet? I'm totally perplexed over this mystery. That is a little black o-ring in a groove around the edge of the disc:

    Looks like a check valve that is in the fresh water inlet connection. There is also a spring and a washer in that connection. Don't know how it got into the water heater unless there is a similar valve there.
