Getting the best RV antifreeze to use for winterizing is the ideal choice. Your RV’s engine and plumbing system can be severely damaged by freezing and expanding fluids that burst out of the lines during the winter season.
However, with the correct antifreeze, both systems can be saved. Frozen pipes can be prevented using standard automobile antifreeze.
This substance is poisonous and can damage the piping. To avoid pipe expansion and explosions caused by frozen water, RV antifreeze, a non-toxic solution, is required.
