Bubble System in Bathtub: Detailed Guide to Air Massage System Components
The components involved in bathtub bubble systems are diverse, and their operating principles differ significantly from those of massage systems using water jets. To make an informed choice when selecting the ideal therapeutic bathtub for your needs, it's essential to understand how these systems are structured and how they function.
A deeper understanding of the roles and interactions of these components will allow you to quickly determine which bathtub bubble system best meets your needs, delivering the optimal massage experience and comfort.
Components of the Bathtub Bubble System
The bathtub bubble system (also known as the air massage system) integrates several key components, including air jet assemblies, high-performance air blowers, manifolds, check valves, hoses, and hose clamps. These components work together precisely to create fine and dense bubbles, providing users with deep relaxation and a soothing spa experience. The system helps alleviate muscle fatigue, promotes blood circulation, and delivers the ideal therapeutic health benefits. Let's take a closer look:

Air blower:
The air blower is used to push air through the pipes into the bathtub, generating bubbles. air blowers typically come in different power ratings and airflow capacities, which can be selected based on the size of the bathtub and the desired bubble intensity.

Air Jets:
Compared to water jets, air jets have a smaller faceplate diameter and are responsible for creating bubbles within the bathtub. They are usually positioned at the bottom or sides of the tub, where air flows through these jets to form bubbles.
Hydrorelax offers air jets made from brass (with some plastic options available), and the jet covers can be made from ABS (chrome-plated), stainless steel, or brass. Surface treatments can be customized according to your preferences, such as chrome plating, painting, brushed finishes, or satin finishes.
Check Valve:
A check valve is a one-way valve that only allows water to flow in a specified direction. Its role in the bathtub bubble system is as follows:
• Preventing Water Backflow into the Air Pipelines: If the water flow is reversed, water could enter the air pipes, affecting the normal operation of the air control valve, or even cause water to backflow, damaging the system.
For instance, without a check valve, when the bubble system is off, water in the bathtub could easily flow through the jets into the water pipes and air intake lines. Once water enters the air lines, the system will lose its air intake function, and the air control valve will no longer work.
Hydrorelax offers a variety of fast connector models, which have distinct advantages over standard connectors:
• Pipe Connection: Used for quickly connecting air hoses, and for splitting or combining air flows.
• Sealing and Leak Prevention: The built-in seal ring and locking mechanism ensure a leak-free connection, even under high-pressure conditions.
• Quick Assembly and Disassembly: No tools are required to secure the pipes. Simply press the blue locking mechanism to easily insert or remove the connectors, making maintenance and part replacement more convenient.

Piping System (Hoses):
The piping system connects the air blower to the bubble jets. Through these pipes, air is transported from the air blower to the jets. The pipes are typically made from materials that are pressure-resistant and heat-resistant.
Air Switch:
The air switch is used to control the on/off function of the bubble system and to adjust the strength or frequency of the bubbles. It can control the circuit through an air pressure signal, perfectly turning the air blower on and off. Of course, if the bathtub has a built-in control panel to start or stop the water pump, a separate air switch may not be necessary.

Why Doesn't the Bathtub Bubble System Need an Air Regulator?  
If you've paid close attention, you'll notice that while bathtub massage systems often include an air Regulator, bubble systems typically do not. Why is that? It's because bubble systems rely primarily on the natural generation of bubbles through the flow of water and air, usually without requiring additional air control mechanisms. The design of the bubble system aims to provide a gentle massage through the air bubbles in the water, rather than relying on strong water flow for deep muscle relaxation.
What Should I Do if the Bubble System's Air Jets Won't Turn Off?
Unfortunately, we often hear complaints from buyers who purchase bathtubs with bubble systems, only to encounter issues. One common problem is that when they try to turn off the air switch to stop the jets, the air jets continue working without any signs of stopping. What's more frustrating is that their bathtubs don't even have a control panel, making it impossible to troubleshoot the issue through the panel. So, what should we do?
After quickly ruling out issues with the air switch and jets (which are unlikely to be the source of the problem), we first check if there are any leaks in the pipes that might be letting outside air into the system. If the above components seem fine, the issue could likely lie with the pneumatic switch on the air blower (a part typically included with the air blower, as shown in the image below). In this case, consider replacing it.
