To empty is pretty easy, you fasten your stopper caps to the valves on the inside of the spa, this will stop the water from escaping. Now remove the pump by loosening the connectors and attach a cap to outlet A. (These caps come with hot tub) Fix the hose adapter to your garden hose and attach both to connector B, make sure that the other end of your hose is at the drain then remove the lower cap from the inside of the spa. Once it’s empty make sure you dry it properly before you pack it away.

It is a reasonably good portable hot tub for people looking for a capacity of 4-6 persons.  When inflated, it has an overall width of 77 inches, which is usually enough to accommodate a tall person. It has a sophisticated digital control panel that ensures automatic start/stop mechanism. There is a LED light as well that show different cycles through 7 colors.
They don’t usually use real water jets, but instead use fans to “blow” the air around (also because of the 120 volt outlet), which causes them to cool down much faster than a regular hot tub. This cooling effect is only made worse by the fact that the materials they are made from lose heat much faster than the materials used on a regular hot tub. All in all, you aren’t likely to get more than 15 minutes to a half an hour of good heat out of an inflatable hot tub.
