Suburban | Water Heater Water Flow Switch | 233665 | Replacement For Suburban Models ST42/ ST60

The Suburban Water Flow Sensor is designed to detect water movement within a plumbing line and convert that motion into a usable signal. As water begins to flow, internal components respond to changes in flow velocity and trigger an output that can be used to monitor usage or activate connected systems. When flow stops, the sensor automatically returns to an idle state until movement resumes.

The sensor operates automatically with no manual input required and adjusts dynamically to changes in water flow. Installed inline, it does not restrict flow direction or impede water travel. The Suburban 233665 provides reliable water movement detection for systems that require accurate flow awareness.

• Slim sensor profile fits neatly within existing pipe sections
• Straight internal bore allows uninterrupted water flow
• Non-metallic exterior is suitable for damp operating environments
• Clearly labeled inlet and outlet ends help ensure proper alignment
• Lightweight design reduces stress on surrounding fittings
