How to deal with water leakage upstairs and downstairs?

Find the property and contact the upstairs owner for handling.

Water leakage is generally divided into two types:

First of all, the broken pipe leads to water leakage.

Second, waterproof is not done well, resulting in water leakage.

First find out the leakage point (around the water pipe, the corner is the leakage area), and then re-waterproof according to the leakage situation.
