As you may already know, draining a hot tub must be done every 3 to 4 months, depending on your usage rate, water quality, and other factors. Not everyone has the time or patience to wait for hours to completely drain a tub using its drain plug or garden hose.
The good news is there are a couple of ways to drain a hot tub that can be used in addition to the drain plug or be combined with other hot tub draining methods for maximum efficiency.
For this reason, we’ve come up with the best pumps for hot tub draining that you can use to speed things up.
Our Top Picks At A Glance
Quick Tips Before Draining Your Hot Tub
Since you’re already planning to drain all your tub’s water, you might as well use a plumbing cleaner or a line flush product so that you can have a much more efficient and cleaner system when you refill it later.
- Unique formula super-cleans the inside of Spa and tub plumbing systems
- Removes oily residues and deposits quickly and easily
- Regular use heps prevent deposits from forming on the heating system
- No harsh chemicals!
This special hot tub cleaner is formulated to break down biofilm and it’s known to cause gross-looking foam to resurface on your tub water. This is not a big deal, since it only means that the product is doing well cleaning out the pipes. Make sure that you let it circulate for at least 20 minutes before you start draining your tub.
A sump pump will drain your hot tub faster than any equipment, but you need to be there when you’re using it to keep an eye on the water level. If your pump continues to run once the tub is empty, the pump’s motor may burn, so you must turn off the pump as soon as the water has been drained.
There are pumps that will get the water down to just a fraction of an inch, while others require a few inches of water to function. Don’t worry, your hot tub’s drain should do the rest and will remove the remaining water out of your tub.

Even though it is not that fast compared to using submersible pumps when it comes to draining your tub, using a wet/dry shop vacuum is still a better option compared to draining with just a garden hose.
Put one end of your vacuum hose into the tub, and connect the other end to your vacuum. Turn its power on for a few seconds until the flow starts moving. You can turn off the vacuum and disconnect the hose from it so that the water can continue flowing out of the tub. While waiting for the water to drain, you can start cleaning the floor and seats of your tub with your vacuum’s wand.
With its larger hose diameter, it’s more efficient in getting water out of your tub than your regular garden hose. Once the tub’s water level is low enough that the siphon isn’t getting any water out, you must hook the vacuum hose back up to your wet/dry vacuum to remove the last remaining water from your hot tub.
