回复 1楼biggirl的帖子 I think it is the secondary drain for heater. If so, it means your primary drain is clogged. In some houses, the primary line drains to a bathroom under the sink. If so, you might be able to clean/clear it yourself.

非常感谢您的回复, 我在网上google了半天, 有人说是 exhaust pipe vent, 和您说的是不是一个东西呀?
This is extra drain line. 你二楼和阁楼有啥dripping pan? 一般是这三种:空调主机,洗衣机,热水器。其中的一个漏水了或者主要滴水管堵了。你查一下这三样东西基本能找到原因。
Thanks!!! I guess it is from the furnace. The problem only happens in winter.
在北方, 现在外面温度大概 35F-40F
