CHLORIDE AND PH
Where the chloride level exceeds 250 mg/L the manufacturer‟s warranty does
not apply to the water heater. In a high chloride water supply, the water can
corrode stainless steel parts and cause them to fail.
Where the pH is less than 6.0 the manufacturer‟s warranty does not apply to
the water heater. pH is a measure of whether the water is alkaline or acid. In an
acidic water supply, the water can attack stainless steel parts and cause them
to fail.
Water with a pH less than 6.0 may be treated to raise the pH. The water supply
from a rainwater tank in a metropolitan area is likely to be corrosive due to the
dissolution of atmospheric contaminants.
