Description
A soft water test kit for checking hardness. It tells you the one thing you actually need to know after a softener is installed or serviced: whether the water leaving it is genuinely soft, and whether the unit is still regenerating properly.
Key details
- Tests water hardness
- Confirms a softener is working and regenerating as it should
- Useful for commissioning a new unit and for routine checks
- Simple enough for a homeowner to run
Where it fits
Keep one on hand if you own a softener. A rising hardness reading is the earliest warning that the unit needs salt, a regeneration, or resin service - well before you see scale or stiff laundry.
