Important warranty information
Your two year Warranty is not valid if the pump has been disassembled in any way.

The Warranty does not cover malfunctioning due to a failure to properly install or commission the pump in accordance with the installation instructions. Correct installation is particularly vital in the case of automatic pumps which will run excessively if the pressure drops in the delivery network.
