When we flush our toilet once the tank fills as does the bowl and we have an incomplete flush. The second flush fills the tank and empties the bowl completely, and the bowl does not refill, but the flush is complete. We have plunged, used unclogging chemicals, scraped rim feed holes, checked that the flapper closes, and confirmed all other tank inards are functioning properly. Please help! Thanks!

Never mind. I just noticed my tube was filling the tank rather than the valve. Not sure how that happened, but the problem is solved.

I assume you mean the small tube(#5 in the image)that fills the bowl as the tank. Just make sure that the small tube doesn't fall below the tanks water level. Attach it to the top of the white overflow tube. Glad you got yourself repaired. Good work! Tom
