How It Works

What goes into the cost.

Real-world install + running costs for whole-house water softeners.

What's Included

  • Install: equipment + professional installation + plumbing
  • Salt: ~40-80 lbs per month for typical family
  • Electricity: ~$3-6/month (timer + valve)
  • Maintenance: resin replacement every 8-12 years
  • Water usage: regen cycles use ~20-50 gal each

System Types

  • Salt-based: Most effective. Uses sodium ion exchange. Best for very hard water.
  • Salt-free: Conditions, doesn't soften. Lower running cost. Best for moderate hardness.
  • Dual-tank: Always-on softening. Best for large families. Higher upfront.
