Frequently Asked Questions
How much does a whole-house water treatment system cost?
A complete whole-house water treatment system costs $3,500-8,000 for standard multi-stage systems and $5,000-15,000 for premium systems. Basic single-purpose systems like softeners ($1,000-3,200 installed) or UV systems ($700-2,000 installed) are more affordable. Total cost depends on water quality issues and treatment needs.
How much does a water softener cost?
Water softener equipment costs $600-2,500 depending on capacity and features. Professional installation adds $300-700, bringing total installed cost to $1,000-3,200. Annual operating costs include $100-200 for salt and minimal electricity, making total annual cost $150-300. Systems last 15-20 years.
Is reverse osmosis worth the cost?
Under-sink RO systems ($350-1,000 installed) are cost-effective for drinking water purification, removing up to 99% of contaminants. Whole-house RO ($2,500-7,500 installed) is expensive but necessary for certain contaminants like arsenic. Annual filter costs are $100-300. Consider your specific water quality issues when deciding.
What is the annual maintenance cost for water treatment?
Annual maintenance costs vary by system: Water softeners ($150-300 for salt), RO systems ($100-300 for filters), UV systems ($50-150 for lamp), iron filters ($100-200 for media), and sediment filters ($50-150 for cartridges). Complete multi-stage systems cost $300-600/year total for all maintenance.
Do I need a UV system for my well?
UV systems ($700-2,000 installed) are recommended if your water tests positive for bacteria or if you haven't tested recently. They're required by many lenders for home sales. UV provides chemical-free disinfection with low operating costs ($70-200/year). All wells with any bacterial history should have UV treatment.
What water treatment do I need for hard water and iron?
Hard water with iron typically requires a two-stage system: iron filter first ($1,200-3,300), then water softener ($1,000-3,200). Total cost is $2,200-6,500 installed. Some combination units handle both but may be less effective for high iron levels. Annual maintenance is $200-400 for both systems.
