Description
The Rinnai 805000061 is an OEM domestic hot water (DHW) flow sensor designed as a direct replacement part for compatible Rinnai tankless water heater systems. This sensor plays a critical role in the operation of your tankless unit — it detects water flow through the system and signals the heater to initiate the burner sequence, ensuring hot water is delivered on demand.
Key Features
- OEM Rinnai replacement flow sensor for DHW applications
- Initiates burner activation upon detection of water flow
- Engineered for precise flow detection to maintain consistent hot water delivery
- Direct drop-in replacement for compatible Rinnai tankless water heater models
- Helps restore proper system operation when flow sensing issues are diagnosed
Why Replace Your Flow Sensor?
A faulty flow sensor is a common cause of no-ignition or intermittent hot water issues in tankless water heaters. When the sensor fails to detect flow, the unit will not fire, leaving you without hot water. Replacing it with a genuine Rinnai OEM part ensures reliable signal accuracy and long-term system performance.
Application
- Compatible with select Rinnai tankless water heater models (verify compatibility with your unit’s model number before ordering)
- Suitable for residential and light commercial DHW applications
