4-Inch Float Flood Guard

This 4-inch float flood guard helps property maintenance teams and plumbing professionals manage drain backups caused by overloaded sewers. It allows normal water flow, then closes the drain opening as rising backup water lifts the float.

The guard operates similarly to a check valve: the float rises during a sewer backup to seal the drain opening and lowers as water recedes. It measures 4 inches wide by 4 inches deep by 3 inches high and uses molded-rubber gaskets with plated or stainless steel metal components. Installation requires a screwdriver. Effective minimum order: 1 unit.

Key Features:

• Float-operated closure: Responds to rising backup water by sealing the drain opening.
• Normal-flow operation: Allows water to pass through the drain until a backup condition occurs.
• Molded-rubber gaskets: Supports a sealed connection at the drain opening.
• Compact 4 x 4 x 3-inch size: Provides a compact flood-control option for applicable drain installations.

Choose this float flood guard for drain installations where temporary closure during sewer backup conditions is needed. Verify compatibility with the intended drain before installation.
