The best water softener is not necessarily the largest or most expensive. It should be matched to your household, water hardness, peak demand and preferred installation location.
Water Softener Selection Checklist
- Water hardness: confirm the hardness level for your property before selecting the resin capacity.
- Household size: consider the number of occupants and typical daily water use.
- Bathrooms: allow for simultaneous use and peak flow requirements.
- Regeneration type: compare metered, timed, electric and non-electric operation.
- Installation space: measure the available cupboard, utility room, garage or outdoor cabinet.
- Drain and power access: check what the chosen system requires before installation.
- Salt storage: consider refill access and the amount of salt you are comfortable storing.
- Future maintenance: ensure there is enough room for servicing and routine salt top-ups.
