Water Treatment Answers is a free service that connects homeowners with local water treatment and filtration companies. We are not a water-treatment company or installer, and we do not perform the work ourselves.
Most water treatment upkeep is filter changes. Sediment cartridges are swapped about every 2 to 6 months, carbon cartridges every 3 to 12 months, and reverse-osmosis membranes every 2 to 4 years. Softeners need salt every few weeks. Always follow the rated life for your specific system, since hard or dirty water shortens it.

No. We're a free matching service. We are not a water-treatment company, installer, or manufacturer, we connect you with vetted local companies who do that work.
Nothing. Our service is free for homeowners. The companies in our network pay us when we refer you, so you're never charged for the connection.
It's the best first step. A water test, from a certified lab, your utility's annual report, or your county health department, tells you what to treat so you don't overpay for a system you don't need.
Hard water, chlorine taste and odor, iron and sulfur, sediment, bacteria in well water, and contaminants like lead or PFAS. We match you with companies that handle your specific issue.
We match you with companies that carry the licensing their state requires and install NSF-certified equipment. Always confirm the details and the warranty before you hire.
Tell us what's wrong with your water, we'll match you with a local company, free and with no obligation.
