Is the leakage in the downstairs bathroom necessarily a problem upstairs?

Downstairs is repairable. In many cases, the upstairs cannot be repaired, and the maintenance from the downstairs on the spot can be done using two maintenance methods: rigid plugging agent and flexible foaming agent. However, it is best to discuss the leakage of the upstairs ceiling with the upstairs neighbor to find out where the water is leaking and find the best solution. >>>More

The leakage on the roof downstairs must be the cause above....There is no water leakage on the top, how can there be water leakage on the ceiling below.

In fact, the water leakage downstairs is not necessarily caused by the water leakage upstairs, but other reasons can also cause water leakage. For example, first check whether the upstairs kitchen and bathroom are waterproof, and whether there is any accumulation of water on a daily basis. >>>More

Not necessarily, I did deal with a problem today, which has nothing to do with the upstairs (or can't be solved from the upstairs). Mainly the water pipe problem. >>>More

Generally speaking, a water leak will not have any effect on the tiles themselves, but a leak in the upstairs kitchen may cause damage to the cabinets installed downstairs, as well as damage to the kitchen circuitry and appliances downstairs.
