	The RainFlo FI-2500 Flow Inducer Pump Station - The balanced flow pump controller provides user-adjustable constant pressure using an energy-efficient variable speed pump motor. Using pressure measurements from the transducer, the controller adjusts the pump speed in order to maintain constant pressure, rather than the traditional on-off switched operation of traditional systems.
	The Rainwater System Controller- The Rainwater System Controller manages all of the functions required in a typical residential or commercial rainwater collection system.
	The Motorized 3-Way Backup Valve, 24V, 1-1/2" - The motorized backup valve is controlled by the Rainwater System Controller and switches between primary and secondary water sources, allowing only one at a time.
	The Reduced Pressure Zone (RPZ) Valve This assembly prevents the possibility of rainwater contaminating a municipal potable water line when municipal water is used for the back-up water supply of a rainwater harvesting system.
	Bulkhead Fittings - (3) 2" bulkhead fittings are supplied for connecting the three tanks together at the bottom so that they act as one large tank. (2) 2" bulkhead fittings are supplied for connecting the vent caps to allow air into the extension tanks. (1) 1.5" bulkhead fitting is supplied for the penetration required to run your pump discharge line out to your irrigation system or structure.
	(2) 2" Vent Cap - Allows air to enter and escape from the extension tanks to allow water to fill the tanks.
	Multi-Tite sealing gaskets - (3) 2" Multi-Tite gaskets used to produce a watertight seal around the upper air balancing lines. (3) 4" Multi-Tite piping gaskets used to create a watertight seal with any penetrating piping.
