Do you have an outside shower? They freeze and burst nicely.
I would purchase a blowout plug and at the very least drain all water and blow out all lines. With heat inside you don't need to drop pink in the traps unless you want to turn the heat off. Or for the $4 you can do that also just in case of a power failure.
Probably cheaper in the long run to blow it out and shut it down for the month with pink in the traps, don't forget to turn off the water heater and drain it also.
