HomeBoost draws water from the mains water supply pipe to deliver an increase of flow into the property. If HomeBoost recognises poor flow (between 3L/min and 12L/min) it will activate the motor and increase the flowrate up to 12 L/min (the maximum allowed pumped flow directly on the mains). Where the flow turbine recognises more than 12 L/min, the signal is sent to the pump to sit in idle mode.
