| Acidity of water measured on a scale from 0-14 called the pH scale. A pH level of 7 is neutral and anything lower than
this indicates acidic water. The lower the number, the more acidic it is. |
|
| Symptom |
Corrosion of brass fixtures, copper plumbing, steel tanks and heating elements, resulting in bluey-green stains on
sinks and bath tubs. |
|
| Diagnosis |
Look to see if there is corrosion of any of the areas highlighted in the symptoms or test the ph of the water by Litmus
paper testing. Blue litmus paper turns red in the presence of an acid. Red litmus paper turns blue in the presence of a base.
If the paper stays the same colour or shows a base is present then you don't have this problem. |
|
| Cure |
Neutralising calcite filter or checmical feed system, using soda ash to remove acidity
(raise pH), or to remove alkalinity (lower the pH) then use white vinegar or citric acid. |
