Getting Your Hot Tub Winter-Ready: The Essential Prep Guide

Safety First: Powering Down Your Spa

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

Your Winter Prep Shopping List

  • Garden hose (for the big drain)
  • Submersible pump (optional but super helpful for faster draining)
  • Wet/dry shop vacuum (your best friend for water removal)
  • Soft cloths and fluffy towels for cleaning and drying
  • Hot tub-specific cleaners (not household cleaners!)
  • Filter cleaning solution
  • Hot tub antifreeze (propylene glycol, the non-toxic kind)
  • Funnel for pouring antifreeze into tight spaces

Hot Tub Winter Prep: The Do’s and Don’ts

Do’s

  • Check your owner’s manual for specific winterization tips
  • Regularly peek at your winterized tub for snow buildup or damage
  • Give filters a thorough cleaning before tucking them away
  • Call in the pros if you’re feeling unsure about any steps
  • Keep water balanced if you’ll be using your tub in winter

Don’ts

  • Wing it without proper knowledge (your wallet will thank you)
  • Use hot water to melt snow (vinyl covers hate this!)
  • Drain your hot tub if you’ll use it now and then during winter
  • Use a tarp as a cover (causes inner foam to get all sweaty)
  • Let water levels drop too low (even in winter, levels matter)

Draining and Scrubbing Your Hot Tub: The Winter Clean-Up Party!

How to Say “Bye-Bye” to Hot Tub Water for Winter

freeze damage

  1. Double-check that your hot tub power is completely off (remember our safety chat?)
  2. Hunt down your hot tub’s drain valve – it’s usually hiding in the equipment access area
  3. Hook up your garden hose to the drain spout and point it somewhere water can safely flow
  4. Open the valve and let gravity do its thing (patience required – this could take hours!)
  5. Want to speed things up? Pop a submersible pump into the lowest spot in your tub

Water Wisdom:

Give Your Hot Tub Shell a Spa Day

  1. Grab a non-abrasive spa cleaner or whip up a simple white vinegar and water solution for scrubbing
  2. Focus extra attention on the waterline – that’s where body oils and gunk love to party
  3. Don’t forget those jets! Clean each opening carefully, fishing out any debris
  4. Stubborn gunk giving you grief? Remove the jets and let them soak overnight in vinegar water
  5. Rinse everything super well and towel-dry to banish all moisture

Filter Care 101

  1. Pop all filters out of their homes
  2. Give them a good shower with your garden hose to blast away loose debris
  3. For the deep-down dirty stuff, let them soak overnight in a filter cleaning solution
  4. Fighting calcium buildup? Try a 1:10 solution of muriatic acid to water (but only after degreasing first!)
  5. Rinse thoroughly and let them completely dry before storage
  6. Tuck your clean, dry filters away in a cozy indoor spot for winter

Hot Tip:

To Drain or Not to Drain? Winter’s Big Question

Keeping Your Bubbles BubblingDraining for Winter Hibernation
The Good Stuff:The Good Stuff:
– Keeps Jack Frost from damaging pipes– Your energy bill takes a winter vacation too
– Ready for impromptu soaks anytime– No need to play chemist all winter long
– Water chemistry stays happy– Perfect for vacation homes sitting empty
– Skip the whole winterization dance– Shields equipment during power outages
The Not-So-Good Stuff:The Not-So-Good Stuff:
– Your electric bill keeps coming– Mess up the draining process? Hello, damage!
– Regular maintenance doesn’t take a holiday– It’s not a quick job
– Power outage? Potential freeze problems– Spring means a complete restart
– Chemistry supplies keep dwindling– Any water left in lines spells t-r-o-u-b-l-e

Hidden Water Hunters: Getting Those Last Drops Out of Your Hot Tub

Your New Best Friend: The Wet/Dry Vac Technique

wet/dry vacuum

  1. Set your wet/dry vac to “blow” mode first
  2. Stick the nozzle into each jet, filter opening, and drain hole
  3. Blast air through for about 10-15 seconds per opening
  4. Flip to “suction” mode and repeat the process (double trouble for water!)
  5. Don’t forget that sneaky filter standpipe—water loves playing hide-and-seek there

Dealing With Air Blowers and Pump Houses

  1. Temporarily wake up your hot tub by reconnecting power
  2. Put the cover on your spa (safety first, friends!)
  3. Run the blower for 30-60 seconds to push water out of those air channels
  4. Quick! Disconnect the power again right after

pump housing

The Final Frontier: Unions and Drain Plugs

  1. Find your hot tub’s access panel (usually held on with screws)
  2. Locate the pump(s) and heater hiding inside
  3. Spot all unions (those big circular fittings connecting pipes)
  4. Gently loosen these unions using your hands or the right tools
  5. Find and remove all drain plugs on each pump
  6. Grab your trusty wet/dry vac again to slurp up any water that escapes

The Antifreeze Adventure: Adding Extra Protection to Your Hot Tub

Antifreeze Application: Where and How?

  1. First, grab propylene glycol-based, non-toxic RV antifreeze specifically made for water systems
  2. Never, ever use automotive antifreeze (ethylene glycol) – that stuff is super toxic!
  3. Pour about 1-2 gallons of RV antifreeze into the filter canister until you see it coming through the suction intakes
  4. Grab a turkey baster (not the one from your kitchen!) to squirt about 1 ounce into each jet
  5. Those fancy whirlpool jets? They’re extra thirsty – give them about 5 squirts each
  6. Don’t miss that tiny ozone jet hiding in the foot-well of your tub

My Top Pick

Putting Your Hot Tub Back Together

  1. Pop all those drain plugs back where they belong
  2. Snug up all unions around pumps and heaters
  3. Re-secure any parts you loosened during your winterization adventure
  4. Double-check everything is properly fastened – water should stay out!
  5. Make sure all access panels are tightly closed
