Buoyancy is a key factor in spa jacuzzi bathtubs helping to relieve lower back pain. In water, the body is supported by buoyancy, significantly reducing the pressure of body weight on the lumbar spine. During light movements in the bathtub, buoyancy reduces the impact on the lower back and alleviates the burden on the lumbar spine.

Modern spa jacuzzi bathtubs typically use residual current devices (RCDs)/GFCIs. Once a leakage is detected, the system automatically shuts off power, preventing electric shock. Electrical components are typically waterproof, such as the pump body, motor housing, and heater housing, which have IP ratings to minimize the risk of water contacting electricity.

• Overheating and Short Circuits: Continuous operation can cause internal wiring to overheat, especially in older spa jacuzzi models. Even bathtubs equipped with leakage protection devices cannot completely prevent hazards caused by aging wiring or component failure.

The inspection interval for a spa jacuzzi bathtub is not fixed and will vary depending on the frequency of use: 1. High-frequency use (daily or multiple times) 2. Moderate Use (1-3 times per week) 3. Low-Frequency Use (several times per month)

A typical spa jacuzzi bathtub holds between 300 and 500 gallons (approximately 1,100 and 1,900 liters). Each time you drain and refill it, you'll incur a water charge. The exact amount depends on local water rates, but typically, draining and refilling costs range from a few dollars to over ten dollars.

A spa jacuzzi bathtub filter can effectively reduce microorganisms and bacteria in the water, especially in hot water, where bacteria are more likely to grow. If the filter is not replaced or cleaned regularly, bacteria and algae can multiply in the water, potentially endangering the user's health.
