Thank you. That was interesting information. Although the penny was only used for scale I still learned something today.This thing is a cent (aka Penny).
It is a type of money.
It is not part of the check valve.

Penny | U.S. Mint for Kids
The penny is the United States one-cent coin. Pennies are made by the U.S. Mint.
Note: The U.S. Mint's official name for the coin is "cent" and the U.S. Treasury's official name is "one cent piece".
The colloquial term penny derives from the British coin of the same name.

I waited to take it apart until I received my replacement parts. The flap didn't go far. I put pool lube on the o-ring and the flap seal. Now I know something else I need to check periodically. At least it is an extremely easy repair.
