Hot tub quarterly care
Quarterly · typically January, April, July, and October
Why it matters
First, the honest gate: no hot tub, no task — skip this card and enjoy your quarter.
If you do have one, here's the truth the chemical aisle won't tell you: hot tub water has a lifespan. It's a small volume of hot water that people sit in — after about three months, dissolved solids build to where sanitizer can't keep up, and you're chasing chemistry that can't be caught. The fix isn't more chemicals. It's new water. Time your winter quarter carefully: in your county's freeze season, never leave a drained tub sitting empty in hard cold — residual water in the lines freezes. Drain and refill same-day, or do the winter change during a thaw.
What skipping it costs
$400–$6,000
No hot tub? Skip this card entirely. Have one? Old water turns on you: sanitizer stops working in water past its prime no matter how much you add, folliculitis ('hot tub rash') is a real dermatology-visit souvenir, and unbalanced water quietly eats the $400 heater element. A neglected tub becomes a $6,000 yard ornament in about two seasons.
Two ways to get it done
Do it yourself
You'll need: Garden hose, Wet/dry vac (makes draining faster, optional), Test strips, Filter cleaner or a second filter to rotate, Sanitizer for refill.
- Test and log. Strips before you drain — knowing where the water drifted helps you balance the refill.
- Drain it. The built-in drain works; a wet/dry vac or a $30 submersible pump does it in a quarter of the time. Send the water somewhere that handles chlorine fine — not the vegetable garden.
- Clean the shell and the filter. Wipe the waterline ring, rinse the shell. Deep-clean the filter (or rotate in a clean spare — the two-filter rotation is the pro move).
- Check the cover. Lift it. A healthy cover is light; a waterlogged one weighs like a mattress and has stopped insulating — that's your heat bill leaking. Sun-cracked vinyl on top speeds it up.
- Refill through the filter well (prevents airlocks), heat, balance, and re-test the next day.
- Once a year, open the equipment bay: look for drips at the pump seals and any rust at the heater. Dry bay, good year.
Hire it out
$150–$350National fair range — local labor moves this number.
A full valet drain-and-refill service runs $150–$350 depending on tub size and haul distance for the water. It's honest money if the lifting and timing don't suit you — the work is real, just not complicated.
What's not honest money: the chemical subscription sold as a requirement, and "water rescue" treatments for water that's simply old. When a tech says your water can't be saved, they're right — and the cure costs a water bill, not a product line.
Ask the tech
- Is this a drain-and-refill visit or a chemical-balance visit? (They're different jobs at different prices.)
- What's the actual condition of the cover — waterlogged, or just dirty?
- Are the heater element and pump seals dry? Show me the equipment bay.
Red flags you're being upsold
- A monthly chemical-subscription box pitched as mandatory. Test strips and a jug of sanitizer are a fraction of the price — the subscription is convenience, not chemistry.
- 'Your water is unbalanceable, you need our proprietary system.' Water that won't balance needs a drain and refill — which is this card, and it's nearly free.
- Cover replacement quoted without lifting the old one. A waterlogged cover announces itself the moment you lift it; a dirty one just needs a hose.
Second opinion time: Any repair quote over $800 — hot tub parts are commodity items with wild markup spreads.
The call
DIY the quarterly drain-and-refill — it's a hose and an afternoon. Hire the annual equipment-bay look if you never open that panel yourself.
