system, and non metallic materials are used extensively. Where metals parts are used
however such as heater elements it is important the water is chemically balanced to ensure
it is not corrosive or scale forming. Waterco will not be responsible for damage caused by
corrosion or scaling.
The chemical balance of water is a relationship between its pH, total alkalinity, calcium
hardness and temperature. your professional pool or spa shop can test the water to ensure
it is chemically balanced in accordance with the langelier Saturation Index.
The water must be maintained at all times as per the following:
pH level
total alkalinity
calcium hardness
And within these tolerances to be balanced to the langelier Saturation Index within a range
of : -0.2 to +0.2
