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


As long as the low parts are not more than half filled with water they
are unlikely to burst.

I agree. As long as you go around and make sure that there are no
deflections of over 1/4 inch anywhere, and everything checks perfect
with a level at all points, you have nothing to worry about.


Same goes with traps. If there is only enough
water to half fill the bottom of the trap, they usually won't split.

Traps will always be full unless they have not been used in long
enough that the water has evaporated.
