🧠 What is the Dometic Stowaway Flow Switch?
The Dometic Stowaway Flow Switch is an intelligent device used primarily in RV and marine water systems. Its job? To monitor and control the flow of water, make sure the pump only runs when water is actually needed. This not only conserves power but also prevents potential damage to the plumbing system.
A flow switch acts like a silent supervisor—it tells your pump when to work and when to rest, ensuring efficient and safe operation of your onboard water system. Dometic, a leader in mobile living innovations, has designed the Stowaway series to blend reliability with smart technology.
🔧 Key Features of the Dometic Stowaway Flow Switch
Here are some standout features that make this switch a favorite:
- Compact Design: Fits in tight installation spots.
- Automatic Activation: Detects flow and engages pumps automatically.
- Durable Materials: Built to resist corrosion and pressure.
- Low Power Consumption: Conserves energy while functioning optimally.
- Wide Compatibility: Works with most Dometic water pumps and plumbing systems.
These features make it perfect for long journeys where a consistent water supply is a must.
🔄 How the Flow Switch Works
The Dometic flow switch operates on a simple principle: it senses the movement of water within the pipe. Once it detects flow, it sends a signal to the pump to turn on. When the flow stops, it cuts the signal—preventing dry runs and unnecessary power usage.
This is critical in mobile systems where resource efficiency matters. Whether you’re showering or washing dishes, the flow switch ensures water and energy are used only when needed.
🚐 Why You Need a Flow Switch in Your RV or Marine System
Still wondering if it’s necessary? Here’s why it’s a must-have:
- Protects Your Pump – Prevents damage due to dry running.
- Enhances Efficiency – Reduces energy consumption by activating only when needed.
- Improves Safety – Minimizes risk of leaks and overheating.
- Boosts Longevity – Less wear and tear on your plumbing system.
Without it, you’re essentially gambling with the health of your entire onboard water system.
