The owners wonder why even "forced" ventilation does not save from dampness
An application has been received to replace a non-working ventilation grill with a fan. I came in, disassembled, in the end it turned out that the engine itself was working, but fell out of the mount, because of this, the blades flew off. And the new grill was larger and did not fit in the old place.
Problem
When I began to check the cravings with a lighter, then rotten from gusts of air. Why else is there forced ventilation? The hostess complained of dampness, which caused blackness to appear on the tiles, and began asking questions. It turned out that the bathroom door is constantly closed, as it interferes with the passage to the kitchen. It was closed very tightly, it's like closing the ventilation with a lid, making it useless.
Solution
He suggested a simple way out, make a hole at the bottom of the door, so that there is air circulation. Faced a misunderstanding the proposed solution happens. Everything was decided by the arrival of her husband, he briefly outlined the situation, he immediately realized what it was about, and gave the go-ahead to work.
I made two holes with a crown in the door, cut off the lintel with a jigsaw, installed decorative grilles on both sides. It seems that the work is simple, but I had to tinker with it to keep it smooth.
He closed the door, put his hand out, there is air movement, which means that everything is working, and now there will be circulation. This method is common, but almost no one uses it. When the door is constantly open, then it's okay, but if it is closed, then it is necessary. Did you know about this method?
