You can use a garden hose to do the job quickly and cleanly. This article explains how to drain a hot tub using a garden hose, with as little fuss as possible. The idea is to create a basic siphon, which will let gravity do the work for you.

Put the open end into the hot tub, and start filling the hot tub. The idea here is to fill the hose with water completely, with minimal air bubbles in the line. ^{[1]

You'll have to hold the kink in the hose until you get the tail end (the end you're holding) below the level of the hot tub. This is where gravity comes into play. ^{[4]

Once you've got the end you're holding (still kinked) below the level of the hot tub, and you're in your pre-selected location for where you want the water to go, let the end of the hose un-kink. The water will start flowing. You've just created a siphon! ^{[5]

- Water "seeks its own level", which is how this system works. The water pressure in the hot tub essentially pushes the water out the hose, because the open end of the hose is lower than the level of the water in the hot tub. Yes, the water has to go up and over the edge of the tub, but here's the neat part––because the hose was full of water, the water inside the hose creates suction at the end inside the tub, which pulls the water over the edge, and flows down the line.

Question

Do I have to unplug it?

Community Answer

In most cases you will not have to unplug anything. You can just drain it as is. It is best to drain it at least twice a year and after winter.

Don't water the plants with the hose. It's de-oxygenated and full of Chlorine!
