If you need to winterize your water system (29 degrees or lower for over 5 hours) and there are no low point drains, consider pouring the pink RV antifreeze into the fresh water tank and let the pump, pump it through the water lines. Make sure you also pour RV antifreeze into each drain to fill the "P" traps. You should pump enough RV antifreeze through the lines until the pink stuff comes out of each faucet. This is for the cold water.
For the hot water lines, I hope your hot water heater has a by pass kit installed. If so, engage the kit to pump the RV antifreeze through the lines. If there is no by pass available, contact a RV service center and by a kit. Then take the drain out of the HWH to completely empty it.
