Knowing I am working on my irrigation skills, a friend called and said her pump had lost its prime. I went there today and this is what I found. Her neighbor broke off one side of the screen with his boat and the pump proceeded to suck up crud. I found this little guy wedged up in the check valve. Replaced the screen and check valve and all is well. I was just glad it was easy-I did not want to look like an idiot in front of one of my friends.
