Nu Aqua products are covered by a one-year limited warranty against any manufacturing defects. However, we do have a 5-year warranty coverage once you register your product on our website. You must have at least one NU Aqua Reverse Osmosis System purchased in brand new condition and register your product within 6 weeks of the purchase date. This is only valid for orders under the contiguous USA. For more information, please visit https://nuaquasystems.com/pages/warranty-registration.
