Suddenly the water stopped, the faucet forgot to turn off, the kitchen leaked and flooded downstairs

I've also experienced such a thing, we lost someone's money in the end, look at your attitude downstairs, talk to him well, and talk to the landlord, let him help you talk, and lose some money appropriately, this is a certainty.

can tell you clearly.

90% of the responsibility lies with you, and the remaining 10% is due to damage to the public drains.

90 percent of your faucets are in your house, and you're responsible for taking care of them, and you said that you turned them on because you saw if there was any water, and you forgot to take care of them, and this was a "human accident" because of your negligence, so you're 90 percent responsible.

The remaining 10% goes to the public unit (property management) (or whoever is responsible for the damage to the section of pipe that connects your room to the downstairs) is responsible for that.

Responsibility is divided in this way, and the key is that the whole incident, the faucet, the drain, is an objective and non-thinking thing, and people are responsible.

Hehe, I hope it helps.
