Draining the hot tub is a necessity for every hot tub owner. The timing of the draining intervals depends on the number of users in the hot tub every day and may be as often as every two weeks for commercial settings or as little as every 75 days for a single user. Many tubs have drains built in at the base of the access panel while others require siphoning. Water the lawn and landscaping beds with the old water, but be sure not to use any chemicals in the hot tub for two to three days beforehand.
Place the end of a garden hose in the hot tub, dropping it straight down into the water so that it lies on the bottom. Turn on the hose until water and no bubbles are coming from the end of the hose.
Turn off the hose, disconnect it from the faucet, and keep it low to the ground. Crimp the hose if the faucet is higher than the hot tub and take the end of the hose to the lowest place in your yard, allowing the water to pour by gravity from the hose.
Go back to the hot tub and make sure the hose stays at the bottom of the tub as the water level drops. Position the end of the hose at the lowest part of the hot tub when the water is almost all drained to suck out the last remaining water.
