Things You'll Need
Draining a spa is necessary to clean the tub or winterize the unit. Arctic spas have a fairly easy draining process that involves connecting a hose to a drain plug. This plug allows for a gravitational flow of water that does not require the use of a pump. Draining the tub is typically necessary every three to four months to thoroughly clean the spa and disinfect the tub.
Turn off power to the spa. You can do this at the ground-fault circuit-interrupter (GFCI) or breaker, depending on your spa's wiring.

Connect a garden hose to the drain valve on the spa. The drain valve should be next to the equipment compartment on the outside of the tub.
Turn the outside ring counterclockwise. This will begin the flow of water to drain the tub. Be sure to place the opposite end of the hose away from the spa and your house.
Vacuum any remaining water in the tub using a wet vacuum.
Disconnect the garden hose and close the drain valve.
If you are winterizing the spa, you will need to follow the specific directions for draining water from the internal plumbing of the spa.
Always refill the spa before restoring power to the unit.
