Zoeller's Home Guard® Max is a high-capacity, high-efficiency, water-powered backup system. With no electricity or batteries required, the Home Guard® Max takes over seamlessly when your primary sump system fails. The Home Guard® Max comes fully assembled for fast, easy and trouble-free installations, and its small footprint allows for installation in even the smallest sump pits. With superior performance and discharge capacity, it uses less water and costs less to operate. The Home Guard® Max, installed as a backup system, does not use any water unless the primary system malfunctions or in the case of power failure. Water flow is equivalent to a normal faucet and is required only when the Home Guard® Max is operating.

This product is not intended for use as a primary water removal unit.
