A spa jacuzzi tub is a complex device consisting of the bathtub body, nozzle system, water pump, inlet and outlet water pipes, electrical control system, reinforcement brackets, and bottom tray. Leaks are usually not caused by a single reason but are the result of a combination of factors, including structure, sealing, and the usage environment.

If your spa jacuzzi tub nameplate clearly displays "Manufacture Date / MFG Date / Production Date," finding the production year is very simple. But if not, we need to continue looking for other methods.

Compared to a regular bathtub, a spa jacuzzi tub contains more complex components such as pipes, nozzles, a water pump, and a motor. These components are interconnected, and any loosening or seal failure in any part can become a potential leak point.

The location of the heater in a spa jacuzzi tub varies depending on the brand and model, but generally, it's installed at the bottom or beside the tub, near the water circulation system. These locations ensure effective heat exchange between the heater and the water flow, thus heating the water.

1. First, add an antifoaming agent – ​​to quickly remove surface foam; 2. Then test and adjust the pH, alkalinity, and chlorine level – to restore chemical balance; 3. Add a cleaning enzyme – to break down grease and organic matter; 4. If necessary, replace part or all of the water – to eliminate the source of foam at its root.

The answer is: not necessarily. While calcium ions can indeed combine with carbonate and bicarbonate ions under certain conditions to form calcium carbonate precipitate, making the water appear whitish or cloudy, the degree of turbidity in spa jacuzzi bathtub water does not accurately reflect calcium content.

Many users believe that having enough manpower is sufficient for moving a freestanding spa jacuzzi bathtub. In reality, this is one of the most common and dangerous mistakes. There are three reasons: 1. Uneven weight distribution 2. Large size and high center of gravity 3. Lack of specialized tools

Add the following to the water: • Professional bathtub drain cleaner (or a mixture of white vinegar and baking soda); • Add as directed and stir well. Turn on all nozzles and the circulation pump, allowing the system to run for 15-20 minutes. This process will thoroughly flush out mold, slime, and impurities adhering to the pipes.

The standard design load-bearing capacity of residential floors is typically 200–300 kg/m². If the spa jacuzzi tub has a small base area, for example, only 2 square meters, but the total weight reaches 800 kg, then the load-bearing capacity per unit area is as high as 400 kg/m², exceeding the normal safe range.

When the pH exceeds 8.0, carbonates precipitate under heating conditions, forming tiny suspended particles. These particles adhere to the foam interface, making the foam stronger and harder to dissipate. Therefore, high pH itself is not a "foam maker," but it is a "foam maintainer."

When we soak in the hot water of a spa jacuzzi bathtub for an extended period, some of the skin's natural oils are removed, and moisture is lost from the stratum corneum, weakening the skin's protective barrier and causing keratinocytes to loosen and shed. This physiological reaction is more pronounced in winter or in people with sensitive skin.

In a spa jacuzzi tub, the surrounding air humidity is high, making it difficult for the body to perceive moisture loss. Even if the body is "sweating," the warm, humid environment causes the sweat to quickly mix with water, so we don't feel it. However, the body's internal water is continuously decreasing through metabolism.
