filtration and local water conditions. Descaling is an important process that removes calcium

deposits, or scale, that can build up inside a tank over time. Calcium and scale is non-toxic but left

unattended, it will hinder your unit's performance.

that descaling is needed. This occurs when scale has deposited on the expansion slot inside the Hot

Tank vent chamber and blocks the normal path for water to expand.

Descaling should take place every 6 to 12 months to preserve the long-term health of your unit. Use

non-toxic cleaner such as ScaleKleen, DEZCAL, 20% Citric Acid Solution, or Undiluted Vinegar

Solution to remove mineral deposits as directed by the manufacturer.
