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:

  • Bucket
  • 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)
  • Descaling solution (vinegar or Calcium, Lime, Rust product)
  •
