How often should I flush my tankless water heater?

  • The timing of how often you flush a tankless water heater depends on the hardness of the water that is going into the unit. Our recommendation is:
    1. Hard Water conditions - especially if you are off of a hard water well with no water softener: 6 months
    2. Regular water or conditioned water - 1 year
    3. Pure water - advanced water filtration or in the Lake Tahoe Basin - 2 years
