Don’t forget the traps. You might want to pour RV anti-freeze in all the traps.
Here is what I got.
If the place is insulated, it takes hours to move indoor temps a few degrees. Expecially if there is not much delta. Meaning if it is 45 degrees inside and outside temps go to 27, it will take probably more than the night-time hours to move that 18 degrees, when the sun arrives again to reverse things.
If this is a cabin, your water supply pipes may not be down deep, and this matters. 1-2 feet does not provide much insulation. 5 feet is better.
As for the keeping a trickle of water flowing, people usually do not understand this. It is not the moving water than stops freezing. It is the fact that the water flow is bringing water in from (however many feet) underground where it is warmer. So it is not water motion that protects, it is the fact that it is warmer water. Do this on a hot water faucet to protect the water heater tank.
