- Find your hot tub’s circuit breaker on your home’s electrical panel
- Flip that breaker to the “OFF” position
Don’t forget to turn off the GFCI (Ground Fault Circuit Interrupter) if your tub has one - Double-check that the power is truly off by looking for any lights or active displays

Draining and Scrubbing Your Hot Tub: The Winter Clean-Up Party!
Ever wondered what happens when water freezes in your hot tub pipes? Nothing good! Properly draining and cleaning your hot tub is the superhero move in the winterization process. Getting every last droplet out prevents frozen pipes and the wallet-emptying repairs that follow once temperatures nosedive. Let’s splash through exactly how to tackle this crucial task!
How to Say “Bye-Bye” to Hot Tub Water for Winter
Ready to drain? This step needs your full attention to prevent freeze damage:
- Double-check that your hot tub power is completely off (remember our safety chat?)
- Hunt down your hot tub’s drain valve – it’s usually hiding in the equipment access area
- Hook up your garden hose to the drain spout and point it somewhere water can safely flow
Open the valve and let gravity do its thing (patience required – this could take hours!) - Want to speed things up?
Pop a submersible pump into the lowest spot in your tub
Water Wisdom: Recently treated your spa with chemicals? Don’t flush that chemical cocktail onto your plants or down storm drains!
Give Your Hot Tub Shell a Spa Day
Once your tub is empty, it’s time for some TLC:
Grab a non-abrasive spa cleaner or whip up a simple white vinegar and water solution for scrubbing - Focus extra attention on the waterline – that’s where body oils and gunk love to party
- Don’t forget those jets! Clean each opening carefully, fishing out any debris
- Stubborn gunk giving you grief?
Remove the jets and let them soak overnight in vinegar water Rinse everything super well and towel-dry to banish all moisture
For sparkling results, I love using the Leisure Time Surface Cleaner from Amazon – it’s specially made for hot tub surfaces and plays nice with acrylic shells!
Filter Care 101
Your filters need special winter prep too:
- Pop all filters out of their homes
Give them a good shower with your garden hose to blast away loose debris For the deep-down dirty stuff, let them soak overnight in a filter cleaning solution - Fighting calcium buildup?
Try a 1:10 solution of muriatic acid to water (but only after degreasing first!) Rinse thoroughly and let them completely dry before storage Tuck your clean, dry filters away in a cozy indoor spot for winter

Hidden Water Hunters: Getting Those Last Drops Out of Your Hot Tub
Think your hot tub is empty after draining? Think again! Sneaky water loves hiding in your spa’s internal components. Getting this hidden moisture out is actually the most crucial step in your winterization mission. Miss this part, and you could be facing repair bills that make your wallet weep! Let’s splash into the nitty-gritty of evicting every last droplet from your spa’s plumbing hideouts.
Your New Best Friend: The Wet/Dry Vac Technique
A wet/dry vacuum isn’t just handy—it’s your secret weapon for proper hot tub winterization. It’s the only reliable way to kick water out of pipes and jets where gravity draining can’t reach.
- Set your wet/dry vac to “blow” mode first
- Stick the nozzle into each jet, filter opening, and drain hole
- Blast air through for about 10-15 seconds per opening
- Flip to “suction” mode and repeat the process (double trouble for water!)
- Don’t forget that sneaky filter standpipe—water loves playing hide-and-seek there
My Go-To Tool: The Shop-Vac 5989300 5-Gallon Wet/Dry Vacuum on Amazon packs the punch you need for serious hot tub winterization jobs.
Dealing With Air Blowers and Pump Houses
Got an older hot tub with dedicated air blowers? These need some special TLC:
- Temporarily wake up your hot tub by reconnecting power
- Put the cover on your spa (safety first, friends!)
- Run the blower for 30-60 seconds to push water out of those air channels
- Quick! Disconnect the power again right after
Rocking a newer model without dedicated air blowers? Lucky you—skip right ahead to handling the pump housing.
The Final Frontier: Unions and Drain Plugs
Now for the last step in your water-busting mission—getting into the spa’s equipment room:
- Find your hot tub’s access panel (usually held on with screws)
- Locate the pump(s) and heater hiding inside
- Spot all unions (those big circular fittings connecting pipes)
- Gently loosen these unions using your hands or the right tools
- Find and remove all drain plugs on each pump
- Grab your trusty wet/dry vac again to slurp up any water that escapes
Keep a thirsty towel nearby to mop up water as it appears. Smart move: snap some before pics of your equipment setup before taking anything apart—your spring self will thank you!
Remember, even tiny amounts of forgotten water can cause massive damage when temperatures drop below freezing. This detail-oriented water removal process might seem fussy, but it’s actually your best insurance policy against a springtime repair bill nightmare!
The Antifreeze Adventure: Adding Extra Protection to Your Hot Tub
After playing water detective and removing every drop from your hot tub’s plumbing, adding antifreeze gives you that extra security blanket against freeze damage. While this step isn’t absolutely required, it’s like insurance for hot tub owners in frosty climates or snowbirds flying south for months at a time.
Antifreeze Application: Where and How?
Getting antifreeze into all the right spots takes a bit of know-how:
First, grab propylene glycol-based, non-toxic RV antifreeze specifically made for water systems Never, ever use automotive antifreeze (ethylene glycol) – that stuff is super toxic! Pour about 1-2 gallons of RV antifreeze into the filter canister until you see it coming through the suction intakes Grab a turkey baster (not the one from your kitchen!) to squirt about 1 ounce into each jet - Those fancy whirlpool jets?
They’re extra thirsty – give them about 5 squirts each Don’t miss that tiny ozone jet hiding in the foot-well of your tub
Putting Your Hot Tub Back Together
Once you’ve given your hot tub its antifreeze cocktail:
- Pop all those drain plugs back where they belong
- Snug up all unions around pumps and heaters
- Re-secure any parts you loosened during your winterization adventure
- Double-check everything is properly fastened – water should stay out!
- Make sure all access panels are tightly closed
Antifreeze Do’s and Don’ts: The Cheat Sheet
Do’s
- Stick with propylene glycol-based, non-toxic antifreeze only
- Take a peek at your manufacturer’s warranty before adding antifreeze
- Apply to all spots where water might sneak in or out
- Schedule extra time for spring startup to flush out all antifreeze
Don’ts
- Touch automotive antifreeze (ethylene glycol) – it’s dangerously toxic
- Forget to flush the antifreeze when firing up your tub in spring
- Bother with antifreeze if you’re 100% sure you got all water out
- Use antifreeze products with metals that could cause corrosion
Hot tub pros don’t always agree about antifreeze.

FAQs
Q1. Is it necessary to winterize my hot tub if I live in a mild climate?
While not always necessary in milder climates, winterizing your hot tub can still be beneficial. It helps prevent damage from unexpected cold snaps, saves on energy costs, and allows for thorough cleaning. However, if you plan to use your hot tub regularly, maintaining it at a lower temperature might be more practical.
Q2. How much antifreeze do I need to winterize my hot tub?
Typically, 1-2 gallons of non-toxic RV antifreeze is sufficient for most hot tubs. Pour about 1-2 gallons into the filter canister and use a turkey baster to add small amounts (around 1 ounce) into each jet. Remember to use only propylene glycol-based antifreeze specifically designed for water systems.
Q3. Can I simply drain my hot tub and leave it empty for winter?
While it’s possible to drain and leave your hot tub empty for winter, it’s not recommended without proper winterization. You must disconnect the heater, remove water from the pipes, take out drain plugs from pumps and filters, and thoroughly clean the tub. Improper draining can lead to damage from residual water freezing in the system.
Q4. Where should I add antifreeze in my hot tub during winterization?
Add antifreeze to all openings where water can enter or exit the system. This includes pouring it into the filter canister, using a turkey baster to add it to each jet, and applying it to the ozone jet in the foot-well. Don’t forget to add some to any other openings through which water may enter or leave your spa.
Q5. What’s the most important step in winterizing a hot tub?
The most critical step in winterizing a hot tub is removing all water from the internal components. Even small amounts of water left in the system can freeze and cause significant damage. Use a wet/dry vacuum to blow out and suction water from all jets, filters, and plumbing lines. This step is crucial for preventing costly repairs due to freeze damage.
