As Chuck said, the flush is for the black tank. You should be hearing a "buzzing", "whirring" noise if it working. If not the anti siphon is defective. Best case scenario is that it is just not passing water (or it can back up upon connection and shower you when it's 30 degrees) or it can just back up and leak water into the trailer. If you don't hear those noises the water isn't going anywhere...it is blocked.
