这是租客发给我的邮件，看来做地主不光是要通马桶，而且要通烘干机的出风口。请问怎么找到出口，怎么通？地主们一般都管疏通吗？第一次碰到这请求。洗衣房在二楼，谢谢！
“I have an error that keeps coming on my dryer (flow sensor) error. I looked into it and saw that it indicates a possible blocked vent. We took the dryer out and checked behind if there was any blockage in vent behind the unit and there was none. My next action was to check if the vent opening outside the house was not blocked or at least was receiving a good amount of the forced air that comes out of the dryer. However, I couldn't locate the vent outside the building. I read that a blocked dryer vent is a fire hazard. Knowing this, would you mind locating the vent on the outside and check to make sure its not really blocked.”
