FAQ
What is water hardness?
Water hardness measures the amount of dissolved minerals (calcium and magnesium) in your water. It's typically measured in grains per gallon (GPG) or parts per million (PPM).
How often should I regenerate my water softener?
Most water softeners regenerate every 2-7 days depending on water hardness and household usage. Higher hardness or larger households need more frequent regeneration.
What type of salt is best for water softeners?
Pellet salt is most common and cost-effective. Crystal or solar salt works well too. Avoid salt with high additives as they can damage your system.
