Unless the drains were clogged, why would there be any water
in them?

CY: The drains would only have waer, if they were horizontal
runs.


OK. I didn't realize we were talking about incorrectly installed pipes. My
bad.



And
what little is left in the traps would have plenty of room
for expansion.

CY: I think I remember hearing of traps cracking. The ice
expands sideways.

What you need to do is shut off the main water supply valve,
and then drain
as much water as you can from the supply pipes by turning on
ALL the taps,
especially the one in the laundry sink (in the basement), if
there is a tap
down there.

CY: Yes, there is a laundry sink. I'm also concerned the
water pipes may have low spots or horizontal runs. Might not
be able to get there with my generator and compressor.


Just shut off the water and then rent a movie, fer cryin' out loud. :-)
