The Grundfos 5 Year Warranty covers manufacturing or material defects on domestic heating circulators (UPS2 and ALPHA2 series) purchased from 1st January 2014.
As of March 2017 this is extended to the SCALA2 in domestic use and the Amazon shower pump.
This warranty does not cover installation or system design faults, pumps seized due to system deposits or damaged packaging and Grundfos are not liable for any consequential losses. Proof of purchase required, as along with manufacturing date code e.g. PC1401, this will be used for administrating warranty claims. All other Grundfos pumps are warranted for 24 months from installation / 30 months from manufacture (to provide six month shelf life period).
