product or component, only after obtaining a Return Goods Authorization (RGA) number from 
US Water, arranging for freight prepaid, and in conformance with any special packaging and 
shipping  instructions  set  forth  on  the  operation  documentation  or  RGA  instructions,  or  as 
otherwise reasonably required, to US Water’s address set forth below, together with (1) RGA 
number issued by US Water at Customer’s request; (2) proof of purchase and, if necessary, 
proof of installation date; (3) a Return Goods Authorization Form; (4) a description of the sus-
pected defects; (5) the serial number of the US Water product alleged to be defective; and (6) a 
description of the type of water and pretreatment equipment which has been utilized in con-
nection with the product, if any. US Water shall, in US Water’s reasonable discretion, be the 
sole judge of whether a returned product or component is defective in material or workman-

cases, Customer will issue a purchase order or other payment guarantee prior to shipment. If 
the returned part is found to have been misused or abused, or the defective part is not re-
ceived by US Water within thirty (30) days; the Customer will be invoiced for the replacement 
part(s) provided. This Warranty does not cover or include labor and/or travel to the Custom-

expenses will be incurred by the Customer in providing the Warranty Service at any location 
other than US Water’s main headquarters; that is if US Water deems that the product is not 
covered by said Warranty. US Water reserves the right to precondition such travel to Custom-
er’s premises upon prepayment of US Water’s anticipated costs of attending such premises.

bled or otherwise tampered with by anyone other than US Water or an authorized US Water 
service representative; or, if any replacement parts are not authorized by US Water have been 
used, or, the product has not been installed, operated and maintained in strict accordance 
and  adherence  with  the  operating  documentation  and  manuals  for  such  product.  Any  ex-
pressed warranty, or similar representation of performance set forth in the operation docu-
mentation for media or resin incorporated into an US Water product shall be void and unen-
forceable  unless  the  feed  water  requirements  set  forth  in  the  operating  documentation  for
