Toilet constantly refilling - Cadet 3

[eva01]

I have a Cadet 3 I installed about 1 week ago. I've noticed that the water level drops very very slowly. Then at a certain point, the toilet will refill the water level to the original point, and this will repeat. It gets annoying at night, I hear this happening when I'm going to sleep.

What would cause this to happen? Thanks!

The flapper is not seating properly.

Hmmmm Is that all that is wrong with it?

I'm so glad that I don't install them unless they are customer supplied!
