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.
You can cooperate, my side is the water supply equipment.
Of course you can, mainly if you like...
Don't you say, I've rented such a house before, as soon as the switch is turned on, a fan will whine up, expelling the air out, not to mention how fun it is, don't worry about the bad air in the toilet in summer, an exhaust fan, especially fun! >>>More
Look at the floor height and exhaust fan parameters. Generally, 300*400 is also feasible.
Retrofit rainproof louvers or rainproof bends.
