About Waterdrop
- Owner

- Headquarters
- US contact address Ontario, California; manufacturer in Qingdao, China
- How it sells
- Sells from its own Shopify store shipping from US warehouses, and on Amazon (brand story cites its Amazon US store). Footer links to a distributor page and a separate business site (waterdropbusiness.com).
- Installation
- Store copy describes DIY installs (e.g., '30-min Easy Installation' for G3P600; whole-house unit 'pre-installed on the bracket' for DIY). Waterdrop runs an Installation Service Program in which partner plumbers are listed on a 'Locate an Installer' page for customers to contact.
Does Waterdrop fit your water?
What you need depends on your water, not the brand: hardness decides whether a softener is worth it, and PFAS (“forever chemicals”) or chloramine decide which filter. Look up your city first, then compare.
