That's true, but not relevant to this situation. Think about it a moment,
then forget about it. It's the least of your problems. The supply pipes are

During the phase change from liquid water to solid ice, the
water (ice) expands. It can easily crack the pipe. So that
when the weather warms up, the drain trap leaks.

I don't understand. How can freezing of water in a p-trap
present a
significant problem?
