FAQ - How do I descale flush the heat exchanger?
Flushing or De-scaling is part of the regular maintenance of a Noritz heater. It involves circulating a solution of pure vinegar or Calcium, Lime, and Rust product through the heat exchanger using a submersible pump. You will need the following equipment to conduct a de-scale:
- Submersible pump
- Isolator valve kit (installed on heater)
- Water line connections (the isolator valves have a 3/4" hose thread connections on their flush ports)
