Home Guard® Max Installation Instructions

The Home Guard® water-powered pump is best installed as a standby to an electric sump pump. This pump uses water pressure as its power source. The amount of water it will pump varies greatly depending on the water pressure supplied to it. With water flowing the inlet water supply pressure should always be above 22psi.

Please note that although we provide typical installation diagrams and the pump does come with installation instructions, we strongly recommend having a licensed professional plumber install this unit for you. This not only ensures your personal safety, but also that the pump is installed properly according to local plumbing codes and increases the likelihood that the pump will work correctly when needed. You really don't want to find out you've installed the backup pump incorrectly after the fact.
