The bathroom will leak and there will be no electricity for a while, what s going on

If the voltage of the socket is only unstable, then most of it is caused by the poor contact between the "wire lug" screw of the socket and the wire! Tighten and solve the problem! If the screw is "slippery", you need to replace the screw or replace it with a new socket!

Do you have any urgent calls that you have to answer while you go to the bathroom? It's nice to leave that room.

The toilet bowl has dirt, which is the result of the toilet bowl being used for many years, and the ultimate reason is that the façade of the toilet drain is not painted with a glaze coating.

The floor of your home is a prefabricated cement hollow core slab, which will be like this, and you need to re-waterproof it where there is a water source upstairs.

The automatic flushing toilet will be powered off for a while and return to normal for a while, it may be that the power supply is in poor contact, you can ask the maintenance master to check it.
