Washers?

[kacrab10]

We suffered Chas law this past weekend.  After just a three day weekend away we came back to smelly water and had to empty. When we refilled we found two washers in the bottom of the spa but we cant tell where they came from?  Anyone have any ideas where I can start looking? Everything seems to be working fine.

Can you post a picture of them? What did you use to drain the tub?

We drained the tub via the drain in the side with a hose but they aren't from the hose.  I haven't mastered pics yet or we would have the whole spa set up on here!!!  So far everything still works so we will see.
