最近在装修卫生间。其中一条排水PVC管道必须要从户外经过，有一半的管道是埋在地
下的。现在担心冬天很冷的时候会不会管子爆裂，或者有其他问题。有没有类似经验的
大侠解释一下。

Usually, drain pipes don't bust because they are never full of still water.
If you let water drip slowly in cold weather though, ice could accumulate.

PVC会不会被冻得易脆？这里冬天温度最低可以到5F左右。

all plastic gets brittle with cold temperature.
the following helps
1. deep enough
2. add insulation if possible
3. with enough slope to let water out quickly
