What to do if the toilet siphon power is insufficient and the pipe problem is

Hello, I am from Jinyang Plumbing, you can pour a bucket of water in the toilet first, so that you can try whether the toilet flush is not enough, or the pipe problem. The water must be poured down at once to have momentum. If it doesn't work, it's probably a plumbing problem.

But not completely, so that it can be ruled out whether it is not impulse enough. On the contrary, the impulse is not enough, and the water inlet method can be adjusted with a Phillips screwdriver.

The pipeline is not blocked, and the water consumption can be solved if the water consumption is large. If it is blocked, it should be dredged.
