If you're redecorating now (whatever the case may be), it's best not to share it.
That's in your own case.
Yes, but it is best to install a check valve in case the wind is blown back into the bath bomb exhaust pipe and back indoors when the bathroom exhaust pipe is only opened.
Most of it is rainwater coming in from the exhaust pipe outlet on the roof. It's easy to determine, 1 If the water leaks after the wind and rain, it is the rainwater coming in from the roof exhaust pipe. 2 If it rained before but you are sure that there is no wind and rain, and it is still leaking, it may be one or two rooftops.
Look at the floor height and exhaust fan parameters. Generally, 300*400 is also feasible.
Retrofit rainproof louvers or rainproof bends.
This should be the glue at the drainage pipe of the upper bathroom for a long time, and there is also the waterproofing of the upper bathroom is not well treated, and the leakage of the ventilation pipe mouth and the bath bomb exhaust pipe connection caused by downward leakage around the drainage pipe.
