1. If you push the handle and let go it will start flushing, ie the water will rush in but then it will not drain out. After about 5 seconds the water will slowly drain out til nearly nothing is left in the bowl but obviously all your ~feces~ are still sitting there.
2. If you hold down the handle the same thing will happen.
It was working fine yesterday, we have tried plunging.
How do I fix this?
