Factors to Consider When Choosing a Hot Tub Drain Pump

While we’ve given you our top picks for hot tub drain pumps, it’s essential to understand the key factors that should guide your choice. After all, a pump that works beautifully for one hot tub might not be the perfect fit for another.

So let’s dive into the specifics.

Pump Power and Capacity

First and foremost, it’s crucial to consider the power and capacity of the pump. Think of it this way – a strong man can carry more weight than a weaker one in the same amount of time. Similarly, a pump with a higher horsepower can effectively move more water in a given time.

It’s all about finding that sweet spot where the pump’s capacity aligns with your hot tub’s size and frequency of use.

Automatic On/Off Switch

Next on the list is the automatic on/off switch. Picture this – you’re out enjoying a sunny day while your hot tub is being drained. Suddenly, the sky clouds over and there’s a blackout. But there’s no need to panic!

With an automatic on/off switch, the pump will automatically shut off in the event of a power interruption, ensuring the pump doesn’t run dry and prolonging its lifespan.

Compatibility with Your Hot Tub

Finally, don’t forget to ensure the pump is compatible with your hot tub. Yes, a pump might be powerful and feature-rich, but if it’s not compatible with your hot tub, it’s as good as useless. Most hot tub pumps are designed to use either 1.5” or 2” plumbing fittings, so make sure to check this before making your purchase.

It’s also important to consider the size of the pump. If you have a computer, you will have a problem with that.

Step-by-Step Guide to Draining Your Hot Tub with a Pump

Now that we’ve covered the best submersible water pump and what to consider when buying one, let’s shift gears and discuss how to use a pump for draining your hot tub. Shall we get started?

Preparing Your Hot Tub for Draining

Before you start the draining process, you need to prepare your hot tub. Start by turning off the power and then remove the cover.

Setting Up the Drain Pump

With your hot tub prepped and ready, it’s time to set up the drain pump. Start by connecting the pump to a power source, but remember to turn off the power to the hot tub first.

Run the hose from the submersible pump to a discrete part of your yard away from:

  • Flower beds
  • Tree roots
  • Pristine grass

Then simply drop the pump into the deepest part of the hot tub standing upright.

Monitoring the Draining Process

You’re all set and the draining process is underway. But don’t wander off just yet. It’s crucial to keep an eye on the process to ensure the pump is working efficiently and safely.

If the pump falls over, it could trigger the float to turn off which will stop the draining process.

Maintaining your pump is essential for its longevity and efficiency. One crucial aspect is to keep an eye out for any potential deposits or clogs on the pipes and impeller surfaces of the pump, which can be caused by slightly dirty water. And remember, patience is key here!

Getting the last bits of water out after the pump stops

A wet-dry vac is an essential tool for removing the last remaining inches of water from the footwells and bottom of a hot tub after draining most of the water with a submersible pump.

It’s powerful suction capability and versatile attachments allow you to access hard-to-reach areas and remove any residual water. The float switch feature ensures that the vac automatically shuts off when the water level reaches a certain point, preventing any overflow.

With a wet-dry vac, you can quickly and easily remove every last little bit of water from your spa, ensuring it is completely empty and ready for maintenance or storage. It provides a convenient and efficient way to eliminate even the smallest amounts of water, leaving your hot tub dry and well-maintained.

Cleaning the hot tub before refilling

After draining the water from your hot tub using a submersible pump, it’s important to give the spa shell a little TLC to ensure it’s clean and ready for refilling with fresh water.

Start by wiping down the empty spa shell using clean rags and a spa shell cleaner (I like a 50/50 mix of water and white vinegar).

This is an easy way to remove any residue or buildup on the surface. Rinse the shell thoroughly with clean water to ensure no cleaning product is left behind. If need be, use the Wet/Dry vac again to remove the rinse water. As a responsible hot tub owner, maintaining good water quality and cleanliness is crucial.

By taking the time to clean the spa shell properly, you’ll create a fresh and inviting environment for your next soak.

Make sure and repeat the process of draining and refilling your hot tub about every 3-4 months.

Tips for Maintaining Your Hot Tub Drain Pump

Now let’s move on to some pro tips on how to maintain your hot tub drain pump. Just like any other piece of equipment, your pump needs some TLC to perform its best and last longer.

To keep your pump running smoothly, make sure to clean it regularly. 

Regular Cleaning

First up on the maintenance checklist is regular cleaning. Once you’ve finished draining your hot tub, remember to remove the pump. Use a wet and dry vacuum to remove any remaining water from the pump.

Finally, rinse the pump and make sure it’s completely dry before packing it away.

Proper Storage

Next, let’s talk about storage. When your pump is not in use, it’s important to store it in a cool, dry place. This helps to protect it from any potential damage and extreme temperatures.

And don’t forget to keep it out of reach from pesky critters!

Routine Inspections

Finally, don’t forget about routine inspections. It’s a good idea to regularly check your pump for any signs of wear or damage. A quick visual inspection can help detect any potential issues early on, allowing you to address them promptly and keep your pump in top shape.

Regular inspections can help you identify any problems before they become serious, saving you time and money.

Alternative Methods for Draining a Hot Tub (aside from a pump)

While using a pump is undoubtedly the most efficient way to drain a hot tub, there are other methods you can resort to in case of emergencies. 

The simplest way to drain a hot tub without buying an expensive pump is to simply hook a garden hose up to the spigot located behind one of the panels on your hot tub (often, but not always a corner panel).

Alternatively, a 5-gallon bucket combined with a wet/dry vacuum can also be used to drain the hot tub. However, remember these methods might require more time and effort compared to using a pump.


We’ve covered a lot of ground in this post, from the top hot tub drain pumps to the key factors to consider when choosing a pump, and even how to maintain your pump. Remember, the key is to choose a pump that’s powerful, efficient, and most importantly, suitable for your hot tub.

So, there you have it – the ultimate guide to hot tub drain pumps. We hope this post has helped you gain a clearer understanding of what to look for in a drain pump and how to make the most of it. Happy soaking!
