Our exclusive lifetime warranty covers all standard hardware that comes with your stainless steel Berkey system: stainless steel chambers, stainless steel lid, spigot, washers and wing nuts, blocking plugs, and rubber gasket base. If anything fails, we replace it free of charge, no questions asked. You must have purchased through BigBerkeyWaterFilters.com and be on record as our customer.

The manufacturer does not always honor warranty claims for Berkey products purchased on Amazon. While some third-party sellers may be authorized, many are not — and there is no reliable way for customers to verify this before purchasing. Amazon.com itself is not an authorized Berkey dealer.

Yes. BigBerkeyWaterFilters.com has been an authorized Berkey dealer since 2008. We are BBB A+ rated — the only Berkey dealer with this certification. Every product we sell is 100% guaranteed authentic.

Not always. Amazon and Walmart host a mix of authorized and unauthorized third-party sellers. These marketplaces have been unable to consistently verify seller authorization or prevent counterfeit listings. In 2022 alone, an estimated $3 million in counterfeit Berkey products were sold on platforms like Amazon and eBay. We recommend purchasing from an authorized dealer to guarantee authenticity.

Simply contact our U.S.-based customer support team by phone at 877-992-3753 or through our contact page. We verify your purchase on file and ship a free replacement — no questions asked. Our support team is available including weekends.

The lifetime warranty covers all stainless steel hardware and standard parts that come with your system. Filters such as Black Berkey Elements and PF-2 Fluoride Filters are consumable products covered under the manufacturer's separate warranty, not our lifetime hardware warranty.
