Flowlight Booster Pump 2920-24 The Flowlight Booster Pump provides city water pressure, anywhere. It has been a standard in home renewable energy systems since 1986. It is economical for domestic water supply, drip irrigation, and water purification. A booster pump is far more cost effective than an elevated tank, providing pressure equivalent to over 100 feet (30m) of elevation. It uses one third to one half the energy of a conventional AC pump, and eliminates high starting surges. It is more powerful, quieter, and much more durable than plastic RV/Marine pumps. Wearing parts are replaceable, and typically last 5 to10 years. Overall life expectancy is 15 to 20 years. Our complete instruction manual and Easy Installation Kit make this pump simple for anyone to install and service, with no previous experience..
