Switch the circuit breaker connected to your Balboa hot tub to the "Off" position. If you are unsure as to which breaker correlates to the hot tub, turn off the main breaker.
Remove the cover from the front of the drain spigot. Secure a hose onto the spigot. Twist the hose tightly to ensure a good seal.
Run the hose to a drain or onto your lawn. Open the valve on top of the spigot on the hot tub. Allow the hot tub to drain completely.
