FYI, the low point drains, are just that, the low points of the hot (red) and cold (blue) PEX tubing system to drain the system. But, as you might expect, there are places for sure that water will collect. If you don't want to use around two gallons of RV Antifreeze (my expierence) to get good pink/red color flowing from ALL outlets, including the outside hose in the aft sanitary bay, you can hook up an air hose to the city water connection and blow out the standing water. Just be careful of pressures and leave a faucet, and or shower shut off open slightly to be safe.
