- 1). Connect a garden hose to the hot tub's drain valve. Run the other end of the garden hose to a spot where you want the water to drain, such as a ditch. If your hot tub doesn't have a drain valve, you can rent a submersible water pump to drain out the water.
- 2). Run your air blower for 30 seconds, if your hot tub has one. This will remove any water still present in the blower. Turn off the hot tub heater and disconnect the power supply. Turn off power to the socket at the circuit breaker.
- 3). Remove your hot tub's water filters. Rinse them off under running water, and then soak them in the manufacturer's filter cleaner according to the package directions. When the filters are totally dry, store them in a warm, dry place for the winter. Wipe out the filter compartment with a clean towel so there is no water left.
- 4). Loosen any nuts or fittings in the plumbing system. Open all the drain valves. If you cannot hand-loosen the fittings, use an adjustable wrench. This will let any remaining water seep out of the plumbing system and prevent freezing.
- 5). Set a shop-vacuum to "Blow" and place the hose nozzle against each jet valve. Repeat with each jet in the hot tub until no more water comes out. Mop out the bottom and sides of the hot tub with dry towels so there is no moisture left in the shell.
- 6). Replace the spa cover, and then cover the entire hot tub with a spa coverall. These covers reach the floor and will prevent snow from seeping between the cover and the vinyl shell.
