Warranty FAQ
Is the Kind Water warranty transferable?
No. Coverage is limited to the original purchaser named on the sales receipt and does not transfer to a new homeowner or any other owner.
Does the warranty cover installation or labor?
No. Labor, removal, installation and service costs are not covered. Remedies are limited to repair or replacement of defective parts or products.
What voids my warranty?
Common causes include not replacing filters annually as recommended, improper installation, using a city system on well water (or the reverse), unauthorized repairs or modifications, and operating outside the stated water quality, pressure or temperature limits.
I bought my system from a retailer. Am I covered?
Yes, if you bought from kindwater.com or an authorized reseller. Purchases from third-party marketplace sellers that are not listed as authorized are not covered.
Are replacement filters and RO membranes covered?
No. Filters, membranes, O-rings and other consumables are excluded. UV lamps and quartz sleeves carry a 1-year warranty.
General warranty limitations
No labor, removal, installation or service costs are covered. Remedies are limited to repair or replacement of defective parts or products. No incidental or consequential damages are covered, including property damage, loss of profits, downtime or third-party claims. Some states do not allow limitations on implied warranties or exclusions of incidental or consequential damages, so these limitations may not apply to you. These warranties are provided in lieu of all other express warranties.
Use of a city system on a well water source, or a well system on a city water source, voids the warranty. Failure to replace filters annually in accordance with manufacturer recommendations voids the warranty.
