The downstairs toilet ceiling is dry, but the top floors of the bedrooms on both sides of the toilet

First, check how you drain your water.

Is it compartment drain or same layer drainage?

Leaking roof drains from the partition must be a problem upstairs.

For example, the waterproofing of the upstairs bathroom is not done, or other places have been leaking, the key is that you have to find which point is leaking, so as to confirm the responsibility, you talk about the problem of air conditioning pipes, I don't know whether it is directly connected to the sewage pipe or directly discharged to the wall?

If it is discharged directly to the wall, it is possible that the water is flowing backwards due to the high outside of your pipe.

If it is connected to the sewage pipe.

It is possible that there is a problem with the tube connection.

I hope you can find a few key points and solve the problem smoothly!

It's seeping water! Looking for a property, it is generally a drainage problem upstairs! Water seeps on the roof of your bedroom, and after a long time, it will become moldy and black! It's going to come down the wall! Super disgusting!

Wow, you're an intermediary...
