Now, if you change the word "pour" to "pump", you may have a chance
of this discussion ending before a week from next Tuesday.


huh? for most of the houses in az, the water supply enters about 3' up an
outside wall, and all pipes are below the slab except for stubs coming up
where there is a valve.

It's an older house, probably 30 plus years old. VERY easy
to have saggy horizontals.

Is it (typically) easier to pour antifreeze into the pipes,
or blow the water out?

That's my concern. Might be horizontal pipes with sags.

A 1/2 inch pipe that is run more or less horizontal but is
3/4 inch
higher at one end than the other is enough to cause a
disaster.

Now think about how easy it would be for that condition to
exist!
