Will the soft skin part of the toilet inlet be broken if you touch it lightly?

It can't be so delicate, how can it not be touched.

Is the valve open?。。 Is this a new set of drifters??? Press the float on the left to see if it will get into the water, whether the float is too low.

1 may be the middle of the switch leakage, that is, you press the flush that, you see the leakage inside, if not, it is through a pipe of the blue one with a ticket that, you can turn the plastic screw, let the float down, generally my experience is that the middle of the leakage, you turn it off, with a Phillips screwdriver cow tight screws.

The float is broken or not adjusted well.

If the float is broken, you can replace it with a plastic bottle, and if it is not adjusted well, you can do it yourself, which is very simple. >>>More

See if the water inlet switch below has been turned off by your child.
