How to flush a Tankless Hot Water Heater with vinegar. Clean the filters and dirt trap maintenance.

FANTASTIC VIDEO!!! The previous owners of our home neglected to tell us (1st time homeowners) this needed to be done. We have really hard water (requiring a double filtration system). Do you simply repeat the vinegar process a few times since this’ll be the first time in five years that we’ve done it? Again, thank you!!
