Frequently Asked Questions
- How much does water treatment & softeners cost in Boston?
- An under-sink reverse osmosis system runs $300–$800 installed. A standard water softener is $1,500–$4,000 including installation and plumbing connections. Well water treatment systems with multiple stages (sediment, iron, softener, UV) can run $3,000–$8,000. Annual maintenance (filters, salt) is $100–$300.
- How do I find a reliable water treatment & softeners contractor in Boston?
- Start with a water test — a good installer will test your water before recommending a system. Ask about ongoing maintenance costs (filter replacements, salt, UV bulb changes). The cheapest system isn't the best deal if filters cost $200 every 6 months.
- Do I need a permit for water treatment & softeners in Boston?
- Simple point-of-use filters don't need permits. Whole-home systems that tie into the main water line may require a plumbing permit. Well water treatment systems may need health department review in some areas.
