How to Drain a Hot Tub

For the safety of everyone using your hot tub at home, it’s best to drain the water occasionally even if you’re sure that it’s always treated. Just follow the simple steps below:

Before draining
The first thing to do is to turn off the heater on the hot tub and switch it off at the main supply. Next, locate the circuit breaker for the tub in the breaker box and turn that off as well. Electrical safety is absolutely vital when dealing with appliances that use water and failure to follow these steps can be exceedingly dangerous.

During draining

Step 1
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.

Step 2
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.

Step 3

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. Source: Hunker

After draining
A lot of cities have laws that require you to drain your hot tub water into the sewer system. Those cities typically provide sewer access through a special drain somewhere on your property.

This is not to be confused with a storm drain, where you should never dispose of hot tub water because those drains lead to natural bodies of water. Drained spa water can harm fish and other wildlife.

If you don’t have direct sewer access, you can run a hose into the drain in a utility sink in your home, or water your lawn or gardens with the old spa water, provided you’ve allowed chemical levels to dissipate. Plants don’t exactly thrive on chlorine. Source: SwimUniversity
