What’s the Fastest Way to Drain a Hot Tub?

There are three methods for draining a hot tub: using the drain spigot, using a submersible pump, or using a wet/dry vacuum. The method using the drain plug or siphoning water through a hose can take hours to complete, so let’s learn the quickest method for draining your hot tub. 

How to Drain a Hot Tub Fast

Before getting started check the ordinances in your area for any guidance or restrictions on discarding chemically treated water. Some towns may have laws on emptying pool or hot tub water into the street or within your own yard. Knowing this info before getting started will save you from headaches later on.

The fastest way to drain your hot tub is to use a submersible pump to forcibly move the water out. Attach an outflow hose to the pump and place it on the floor at the center of the tub. See if the other end of the hose is long enough to reach the nearest drain or sewer. If it isn’t, attach a garden hose to the outflow hose to extend it. Then turn on the pump and let it remove the water.

To get rid of the leftover pools of water, place the pump directly into a puddle to siphon the water out. Make sure to keep an eye on the pump so that it’s always drawing water in; taking in too much air can cause the pump to overheat.

Other Ways to Drain Your Hot Tub 

Using a wet/dry vacuum is slower than a submersible pump, but faster than the drain spigot. Attach the vacuum’s hose to the machine and place the open end of the hose in the water. Turn it on so water starts flowing through the hose and once it does, turn it off and disconnect the hose from it. The water should continue to flow, so put the open end of the hose over a drain or sewer to let the water pour directly into it.

If your drain spigot is located over a drain in the ground, just open the valve and allow the water to flow into the drain. If the drain/sewer is farther away, attach a garden hose to the spigot, put the other end over the drain, and open the valve. If your drain is uphill from your tub, you’ll need a submersible pump to drain it completely. It’ll take 1-2 hours to drain it through the spigot. 

Once the water in your tub becomes too shallow to be siphoned or drained out effectively via the spigot, you’ll need to use a wet/dry vac to draw out the remaining water. Make sure you vacuum up all the small pools of water remaining in your hot tub.
