How Often Should I Change the Water in My Hot Tub?

You should change your hot tub water every 3–4 months to maintain cleanliness and water quality. Heavy usage or improper chemical balance may require more frequent changes.

The Importance of Changing Hot Tub Water

Regularly draining and refilling your hot tub is essential for maintaining hygiene, water clarity, and equipment longevity. As contaminants accumulate, they not only affect water balance but can also strain filters, pumps, and jets. Changing the water helps reset chemical levels, ensuring a healthier soaking experience while preventing long-term damage to your hot tub components.

Over time, hot tub water accumulates body oils, lotions, sweat, and other contaminants that affect water quality. Even with regular chemical treatment, total dissolved solids (TDS) build up, making it harder to maintain water balance and sanitation.

Signs That Your Hot Tub Water Needs Changing

If you notice any of these signs, it may be time to drain and refill your hot tub:

• Cloudy or foamy water: Indicates excessive contaminants or chemical imbalance.

• Strong odor: A musty or chemical smell suggests poor water quality.

• Irritated skin or eyes: Can be caused by imbalanced chemicals or high TDS levels.

• Difficulty maintaining balance: When pH and sanitizer levels fluctuate frequently.

• Slimy or sticky surfaces: Biofilm buildup can make the hot tub feel slippery.

Step-by-Step Guide to Changing Hot Tub Water

Performing a thorough water change ensures your spa remains clean and well-maintained. Taking the time to properly drain, clean, and rebalance your hot tub will help extend its lifespan and improve the overall quality of your soaking experience.

Follow these steps for a proper water change:

1. Turn Off Power: Shut down the hot tub to prevent damage to the pump and heater.

2. Flush the Plumbing: Use a hot tub system flush to remove hidden biofilm and bacteria.

3. Drain the Hot Tub: Use the built-in drain or a submersible pump for faster draining.

4. Clean the Interior: Scrub the tub’s surfaces with a non-abrasive cleaner.

5. Rinse and Refill: Rinse thoroughly and refill with fresh water.

6. Balance Chemicals: Test and adjust pH, alkalinity, and sanitizer levels.

7. Run the System: Turn the hot tub back on and circulate water for proper mixing.

Extending the Life of Your Hot Tub Water

Proactive maintenance helps keep your water fresh for as long as possible, reducing the frequency of full water changes. By following smart hygiene practices and using high-quality water treatments, you can minimize contamination and improve overall water longevity.

To extend the time between water changes, follow these best practices:

• Shower Before Entering: Removes body oils, lotions, and sweat.

• Use a Hot Tub Cover: Prevents debris and contaminants from entering.

• Maintain Proper Chemical Balance: Keeps water sanitary and reduces buildup.

• Clean the Filter Regularly: Rinse weekly and deep clean monthly.

• Shock the Water Weekly: Eliminates organic contaminants and improves water clarity.
