What it means for your home
Soft water leaves almost no scale. Kettles, showers and appliances stay clean for a long time.
You do not need a softener. Use a low detergent dose: more only leaves residue.
How often to descale
As a rule of thumb for soft water, kettles and shower heads need descaling every three or four months. Descale whenever you see scale building up.
Common questions
Is hard water bad for you?
No. Hard water carries calcium and magnesium, minerals the body uses. Whether tap water is safe depends on germs and pollutants, which water companies test for, not on hardness.
Do I need a water softener in High Peak?
The water company's figure for High Peak is 51 mg/L (3.6 °Clark), which is soft water. Usually not straight away. Set the dishwasher, dose detergent for your band and descale regularly. Get quotes for a softener only if scale is clearly damaging your boiler or appliances.
How do I find the value for my address?
Use your water company's postcode checker. Hardness can differ between districts, so check your own postcode, or test with strips or a drop test.
