Renting a EcoWater water softener
1 documented EcoWater rental offer from 1 state, read on 2026-10-04.
Reported rents: no documented price dated within 24 months of 2026-10-04.
Rentals at an advertised starting price: $35.00/mo–$35.00/mo, median $35.00/mo (n = 1, read on 2026-10-04; sources: dealer page 1).
EcoWater certification listings
As of 2026-10-05, our certification index holds 88 active listings we can attribute to EcoWater, from NSF International, IAPMO R&T and WQA Gold Seal: 22 of them under NSF/ANSI 44 (residential cation-exchange water softeners), all from NSF International.
Listings by standard and certifier: NSF/ANSI 44 (NSF International 22); NSF/ANSI 42 (NSF International 19 and IAPMO R&T 1); NSF/ANSI 53 (NSF International 3 and IAPMO R&T 2); NSF/ANSI 58 (NSF International 10 and IAPMO R&T 1); NSF/ANSI 401 (NSF International 2 and IAPMO R&T 1); NSF P231 (IAPMO R&T 1).
Materials listings, which certify what a component is made of rather than anything it reduces: NSF/ANSI 61 (NSF International 33 and WQA Gold Seal 8); NSF/ANSI 372 (IAPMO R&T 1 and WQA Gold Seal 12).
The NSF/ANSI 44 listings name these reductions: Hardness, Barium, Radium 226/228.
Our index reads only the IAPMO R&T, NSF International and WQA Gold Seal directories (read: NSF International on 2026-10-05, WQA Gold Seal on 2026-10-04, IAPMO R&T on 2026-08-23) and not CSA Group, ICC or UL Solutions, so a listing missing from it is not evidence that EcoWater holds none.
How long it lasts, and the EcoWater warranty
1 source we hold gives a service life for softeners in general, not for one brand: a water softener as a whole unit lasts 10 to 15 years, according to a government source read on 2026-10-04.
Service life (government, read on 2026-10-04)
EcoWater’s warranty, as its own documents state it: ECR3700 spec sheet: salt tank and mineral tank for the lifetime of the original owner; valve body ten years; electronic faceplate seven years; all other parts five years. (The ESD2800 sheet lists different, shorter terms; see notes.) Costco says members get an extended warranty on EcoWater products bought through Costco.
