Regardless of indoor damaged property.

The first thing depends on how long your house has been used.

Because if the decoration is broken after a period of use, you can find property maintenance, but general compensation is still the main responsibility of the second floor and cannot be avoided.

And on the second floor, is the property responsible for maintenance or looking for someone to repair it? You have to go to the scene to see for yourself, and ask the repairman to identify whether the water pipe rupture belongs to the engineering quality problem or the self-use problem on the second floor, or whether it was violently decorated at that time (the water pipe was randomly replaced and changed its original use), and the responsibility will be clear at a glance.

Ps: It hasn't been long since the renovation. If the property fee is too high, you can try to make the property properly compensated, but not every property is treated like this. for reference only

Secondly, if the house has a long service life, this property search is mostly pushed, so compensation can only be found on the second floor.

So we still need the first floor. You should communicate with the second floor.
