Dryer Vent suggestion

[Yuzi Stha]

Hi,

I have a 3 unit house where there are 3 dryers mounted to 1 big exhaust in the basement. I have noticed when one of the dryer is in operation the exhaust air makes its' way to other dryers as well when it is traveling to the main outside exhaust causing one of the dryer to get foggy. I am hoping to get some ideas to understand what you guys do to solve this issue. Is there certain requirement in Massachusetts on dryer vents for multiple dryers.

Also, if you guys know any company who works to fix these issues, that would be great.

Thanks,

Yuzi
