Owning a hot tub offers the perfect way to unwind, ease muscle tension, and enjoy quality time with friends or family. However, proper care is essential to protect your investment and maintain a healthy soaking environment. While most hot tub owners are diligent about water treatments and general maintenance, it’s just as important to know what not to do. Seemingly small mistakes can lead to major issues, costly repairs, or the need for full hot tub replacement services in California.
In this guide, we’ll outline the 10 things you should never do to your hot tub. Whether you’re a first-time owner or a long-time user, avoiding these common missteps will help you preserve your spa’s condition and avoid the need for a hot tub repair service.
Key Takeaways
- Avoid skipping routine maintenance tasks like filter cleaning and chemical checks.
- Don’t overfill or underfill your hot tub—both can lead to mechanical issues.
- Never use pool chemicals or household cleaners in your hot tub.
- Pay attention to your ozonator and circulation system for water clarity.
- Consistent care reduces the need for emergency hot tub repair service in San Marcos, CA.
Neglecting Regular Maintenance
Regular maintenance is the cornerstone of long-lasting hot tub performance. It’s easy to assume your spa is in good shape if the water looks clean, but deeper issues can develop over time.
Failing to inspect jets, pump functionality, or water levels can cause wear and tear. If you ignore routine checks, you may eventually need professional hot tub repair service or even replacement.
Tip: Create a weekly maintenance checklist to stay on top of water testing, cleaning, and equipment inspection.
Ignoring Filter Cleaning
Your hot tub filter traps debris, body oils, and contaminants to keep the water clean and safe. Ignoring filter cleaning leads to clogged systems, restricted water flow, and cloudy water.
A dirty filter also forces the pump to work harder, increasing energy costs and risking equipment failure.
How Often to Clean Filters:
- Rinse with water every 1–2 weeks
- Deep clean with a filter solution monthly
- Replace every 12–24 months depending on usage
Skipping Chemical Checks
Maintaining balanced water chemistry is essential for preventing bacteria growth, skin irritation, and damage to your hot tub’s interior.
Common issues caused by poor chemical balance include:
- Corrosion of jets and pipes
- Algae or biofilm buildup
- Cloudy or foul-smelling water
Use a test strip or digital tester to monitor chlorine/bromine levels, pH, alkalinity, and calcium hardness.
Recommended Ranges:
- pH: 7.2–7.8
- Free chlorine: 1–3 ppm
- Total alkalinity: 80–120 ppm
Inconsistent chemical checks can lead to more serious problems that require expert hot tub repair service in San Marcos, CA.
Not Checking Ozonator Functionality
If your hot tub has an ozonator, it plays a key role in breaking down contaminants and reducing the need for excess chemicals. Over time, ozonators can wear out or malfunction without obvious signs.
A broken ozonator can:
- Increase chemical demand
- Cause cloudy or smelly water
- Result in microbial buildup
Maintenance Tip: Check the ozone output light or consult the manual every 6–12 months to ensure it’s functioning correctly.
Overfilling or Underfilling Your Hot Tub
Water levels must be maintained within the recommended range. Overfilling and underfilling can cause mechanical and safety issues.
Risks of Overfilling
Overfilling your hot tub can:
- Cause water to overflow into the electrical components
- Lead to flooding around the equipment
- Put pressure on seals and fittings
Always check the maximum fill line and never add water beyond it, especially after multiple users enter the tub.
Dangers of Underfilling
Low water levels can:
- Expose the pump and heater to air, causing overheating or failure
- Prevent proper filtration and circulation
- Lead to dry running, which may result in a costly hot tub repair service
Monitor the water level regularly and top off as needed.
Using Incorrect Chemicals
Hot tubs require specific chemicals designed for smaller volumes of hot, circulating water. Using the wrong products can damage your spa and irritate your skin.
Avoid Pool Chemicals
While pool and spa chemicals may seem similar, they’re not interchangeable. Pool chemicals are stronger and formulated for large volumes of water, which can:
- Over-sanitize the water
- Damage acrylic surfaces and plumbing
- Throw off water balance rapidly
Proper Chemical Usage
Use spa-specific products for:
- Sanitizing (chlorine, bromine)
- pH and alkalinity control
- Scale prevention and water conditioning
Always follow manufacturer guidelines and never mix chemicals, as this can create hazardous reactions.
Using Household Cleaners
Cleaning your hot tub with standard household products might seem harmless, but many of them contain harsh chemicals that damage spa surfaces and plumbing.
Avoid:
- Bleach
- Dish soap
- Bathroom sprays
Instead, use non-abrasive spa cleaners or diluted white vinegar for surfaces and a specialized filter cleaner.
Leaving the Cover Off
Leaving your hot tub uncovered can expose it to debris, UV rays, and wildlife. Over time, this can:
- Contaminate the water
- Increase heating costs
- Wear down internal components
A secure, insulated cover also prevents evaporation and maintains water temperature.
Pro Tip: Clean and condition your spa cover regularly to extend its lifespan.
Allowing Water to Sit Stagnant
If your hot tub isn’t in regular use, stagnant water can become a breeding ground for algae, mold, and bacteria. Still water can also clog filters and damage circulation pumps.
If you plan to leave your hot tub unused for an extended period:
- Drain and clean the spa thoroughly
- Dry the lines and remove filters
- Store with a cover on in a shaded area
Long-term neglect can result in damage that may only be resolved through hot tub replacement services in California.
Ignoring Signs of Trouble
Odd noises, cloudy water, or a drop in water temperature may indicate deeper issues. Ignoring these signs can turn a minor fix into a major repair or full system failure.
Early signs to watch for:
- Unusual smells or foaming
- Heater not maintaining temperature
- Decreased jet pressure
Prompt attention and minor fixes can help avoid the need for more extensive hot tub repair service later.
