Megaflo Servicing explained
Megaflo servicing follows the Heatrae Sadia schedule so the warranty remains valid and the cylinder keeps full hot water capacity.
- Air gap or vessel recharge: Interpret readings against operating conditions and equipment specification; do not assume a recharge is the answer.
- Safety valve testing: Check movement, control command and the effect on flow together; the actuator and valve body can fail independently.
- Immersion element inspection: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
- Benchmark logbook: Confirm the component identity and model-specific requirements before deciding whether adjustment, testing or replacement is appropriate.
Interpreting the reported fault
A planned visit should establish condition and identify deterioration. An existing fault may need separate diagnosis and parts. Agree which assets, cleaning tasks, functional checks and records are included, and base the interval on manufacturer guidance and operating conditions.
- Reported symptom: a Megaflo Eco or Eco Plus due its annual check
- Record when the problem started and any recent changes
- Keep fault codes and model details for the assessment

A planned visit should establish condition and identify deterioration. An existing fault may need separate diagnosis and parts. Agree which assets, cleaning tasks, functional checks and records are included, and base the interval on manufacturer guidance and operating conditions.
