Frequently Asked Questions
- Does Olathe water need softening?
- Yes, water hardness runs 10-15 grains per gallon, well above the 7 gpg threshold where softening becomes economically valuable. Without softening, dishwashers, ice makers, water heaters, and washing machines see reduced lifespan.
- Single or twin-tank?
- Twin-tank softeners (Kinetico, EcoWater) provide continuous soft water without regeneration interruption. Single-tank systems regenerate at night, leaving 6-8 hours of unsoftened bypass water. For households running early-morning showers and laundry, twin-tank pays back in user experience.
- What's typical install cost?
- A whole-home softener install runs $2,200-4,500 in Olathe including the unit, plumbing modifications, drain connection, and electrical. Twin-tank systems run $3,500-6,500. Reverse osmosis adds $500-1,200.
