Hot Tub Frequently Asked Questions
Q: Can any Sundance® Spa operate on 120V electrical service?
A 240V spa delivers roughly four times the heater output.
If using 120V, it must be on a dedicated circuit with proper amperage and no shared appliances.
Q: What’s the purpose of a circulation pump?
Spas without one rely on a large jet pump cycling on and off, which is louder and less efficient. Circulation pumps deliver better filtration, quieter operation, and lower energy use.
Q: Does a bigger pump give a better massage?
Effective hydrotherapy depends on jet design, plumbing efficiency, and water flow control.
A well-engineered spa with lower horsepower can outperform a poorly designed spa with a larger pump.
Q: What is hydrotherapy?
- Heat increases circulation and loosens tight muscles.
- Massage jets relieve tension and help accelerate the body’s natural healing process.
- Buoyancy reduces body weight by up to 90%, easing joint pressure.
Q: What does a pump’s horsepower rating really mean?
- Continuous Operating HP — the actual horsepower delivered while running.
- Brake (Marketing) HP — a momentary start-up rating used for advertising.
Q: How many jets are adjustable?
Sundance® prioritizes ergonomics, targeted therapy, and purposeful plumbing rather than adding large numbers of non-adjustable jets.
Q: How often should I clean my spa?
The process is simple and typically takes about an hour.
Q: Can a hot tub be installed indoors or outdoors?
For indoor installs, ensure:
- There is enough access for delivery.
- The flooring supports the filled weight (a 3-person spa weighs ~2,500 lbs / 1,150 kg).
Q: How much should I expect to spend on a hot tub?
Sundance® offers a range of models for different budgets, and our team at Main Street Pool & Spa will help you choose the right spa for your home and lifestyle.
Q: What should I consider before buying a hot tub?
- Ensure the seating is comfortable and supportive.
- Water should reach shoulder height for proper hydrotherapy.
- Test the jets for at least 15 minutes to confirm comfort and pressure.
Q: What does free delivery include?
- Clear access to the hot tub location
- Electrical work to bring power to the site
- Fence removal, grade challenges, or deck navigation
- Crane, material handler, or forklift services
Q: Is hot tub maintenance difficult?
Basic maintenance includes:
- Water: Test weekly; drain every 3–4 months.
- Filters: Rinse monthly and replace as needed.
- Cover: Protects water from debris and weather.
Q: How is a hot tub installed?
- A proper foundation (concrete pad, patio stones, or reinforced deck)
- Correct electrical service for your chosen model
