4" First Flush Diverter Kit

Downspout First Flush Water Diverters improve water quality and reduce tank/cistern maintenance by preventing the first flush of water, which may contain roof contaminants, from entering the tank/cistern. First Flush Diverters help ensure cleaner water is available for use, which protects rainwater pumps and internal household appliances such as clothes washing machines, toilets, hot water systems, etc.
