re: Roof vent cap on bath exhaust vent
The vent cap has a screen and damper. However, in strong gusts of wind, the wind creates a negative pressure that sucks the damper open and then slams it shut. This is annoying and actually wakes me up during the night. Is there a way of preventing or fixing this?
