Here’s what NOT to do:
-Don’t look at it
-Don’t touch it
-Don’t put anything inside of it
Of course, I can’t resist fiddling around with things of a mechanical nature so these rules don’t apply to me. Actually, all I wanted to do was take a leak and for some reason water begins to fill the bowl shortly after I pump it dry. After several hours of dicking around with it and copious swear words I come to find out that the tiny check valve in the anti-siphon loop was stuck allowing water back flow into the bowl.
