If you’re wondering how to drain a hot tub, whether it’s your first time or you just need a refresher, you’re in the right place. Draining your hot tub is a vital part of maintenance that keeps the water clean, extends the life of your tub, and ensures all the systems keep running smoothly.
In this guide, we’ll walk you through draining a hot tub using both the built-in drain valve and a hot tub draining pump. We’ll cover everything in everyday terms with just the right touch of technical know-how so you feel confident doing it yourself.
Why Draining Your Hot Tub Matters
Hot tubs don’t filter everything out lotions, oils and chemicals build up over time. Even with sanitiser, water needs to be changed every 3 to 4 months (more often if you use it heavily). Regular draining keeps your hot tub fresh, prevents cloudy water, and protects your pumps and filters from damage.
What You’ll Need
Before you begin draining your hot tub, make sure you’ve got the following:
A garden hose (for gravity draining)
A hot tub draining pump (if you want to make things faster)
A flathead screwdriver (optional, for some drain valves)
A bucket and towels for residual water
White vinegar or mild cleaner (for wiping down the tub after draining)
How to Drain a Hot Tub
Using the Drain Valve (Gravity Method)
This is the most basic way to drain a hot tub. It takes a bit longer than using a pump, but it gets the job done.
1. Turn off the Power
Always switch off your hot tub at the breaker before starting. This protects your pump and heater from damage while the water level drops.
2. Locate the Drain Valve
Most hot tubs have a drain spout on the side, near the bottom. You might need to remove a panel to access it.
3. Connect the Hose
Attach your garden hose to the drain valve. Make sure the other end of the hose is directed toward a suitable drainage area ideally a storm drain or an area that won’t get waterlogged.
4. Open the Valve
Twist or pull the valve (depending on the model) to start draining the hot tub. Some valves require a flathead screwdriver.
5. Wait
This part can take 1–2 hours, depending on the size of your hot tub and the slope of your drainage area.
6. Use a Bucket for Residual Water
Once the water is mostly gone, there may still be some left in the footwell or seats. Scoop it out with a bucket or sponge and towel dry.
How to Drain a Hot Tub with a Pump
Using a hot tub draining pump is by far the quickest and easiest method especially if you’re short on time or just want to avoid waiting around.
1. Turn off the Power
Always power off the hot tub first.
2. Submerge the Pump
Place your hot tub draining pump into the deepest part of the tub. Attach the drain hose and run it out to your drainage area.
3. Switch on the Pump
Most submersible pumps are electric. Plug it in and watch the water start to flow fast.
4. Monitor the Level
Stay nearby the pump can empty the tub in as little as 10–20 minutes depending on the capacity and pump power.
5. Handle Remaining Water
Just like the gravity method, finish by mopping or scooping out any water the pump couldn’t reach.
6. Use a Bucket for Residual Water
Once the water is mostly gone, there may still be some left in the footwell or seats. Scoop it out with a bucket or sponge and towel dry.
After You Drain The Hot Tub
Now that your hot tub is empty, it’s a good time to give it a wipe-down with a mild cleaner or white vinegar. Don’t forget the filters too rinse them or replace them if needed. Then it’s time to refill the hot tub, turn the power back on, and balance the water chemistry.
Tips for Easier Hot Tub Draining
Plan your draining day on a warm, dry afternoon so water doesn’t freeze or flood your garden.
Use a hot tub draining pump if you have poor garden drainage or just want to make things easier.
Keep a maintenance log so you remember when you last drained and cleaned it.
How Often Should You Drain a Hot Tub?
For most households, every 3 to 4 months is ideal. If you use your hot tub daily or host a lot of guests, you might need to do it more often. Water clarity, chemical balance issues, and strange smells are signs it’s time.
Knowing how to drain a hot tub is one of those homeowner essentials. Whether you go with the gravity method or invest in a hot tub draining pump, keeping your spa clean starts with regular draining. Do it right, and you’ll enjoy clearer water, healthier jets, and longer-lasting equipment.
