When storing hot-tub for up to 5 months do you have to put something in the pumps so they won't get rusty or damaged?

Yes, when storing a hot tub for an extended period, such as five months, it's important to take precautions to protect the pumps and other components from damage. Drain all water from the hot tub, including the pumps, and ensure they are completely dry to prevent rust and corrosion. Additionally, consider using a pump lubricant or anti-corrosion spray specifically designed for this purpose, and store the pumps in a dry, temperature-controlled environment to further prevent damage.
