Why Ontario wells are tricky
Rural Ontario groundwater frequently carries hardness plus iron, manganese or sulphur. A softener bought for hardness alone can foul quickly.
Sensible order of operations
- Lab test
- Sediment and iron/sulphur as needed
- Softener sized to grains and peak flow
- UV for bacteria risk
- Kitchen RO for drinking water
Municipal Ontario note
City homes in the GTA, Ottawa and southwestern Ontario more often start with softener plus carbon, then RO.
