What Happens If I Don’t Use My Hot Tub for a While?

Life gets busy, and sometimes your hot tub may sit unused for weeks or even months. But what happens to your water and spa during that downtime? Understanding this can help you avoid surprises and keep your spa ready for a relaxing soak whenever you’re ready.
Water Quality Declines
Even when not in use, your hot tub water is a living environment. Without regular circulation and chemical maintenance, bacteria and algae can start to grow, leading to cloudy, smelly, or slimy water. The chemicals you added will naturally break down over time, reducing their effectiveness.
Filters Can Get Clogged
If the water isn’t circulating, debris and contaminants settle, making your filters work harder or clogging them altogether. Dirty filters reduce water quality and can cause damage if left unattended.
Potential Equipment Damage
Standing water with unbalanced chemistry can lead to scale build-up, corrosion, or biofilm forming inside pipes and jets. Over time, this can shorten the life of your spa’s pump, heater, and other components.
What Should You Do?
Run the jets and circulation daily for at least 15-20 minutes, even if you’re not soaking.
Test and adjust water chemistry weekly to keep sanitiser and pH levels in check.
Use a Spa Flush product before a long break to clean the plumbing and prevent biofilm build-up.
Consider draining and refilling if you plan to leave it unused for several months.
