Davey Pump Pressure Booster 20 GPM 40 PSI Boost 1 HP 230V #BF20-40 with flow control, are ideal for shower boosting applications. They are not recommended for whole home applications. It requires a minimum of 20 psi inlet pressure for the flow control to operate

Applications:

• Shower boosting and irrigation applications only, they are not recommended for whole home applications.

Operation:

• When the flow is more than 1.2 GPM the pump will turn on and give up to an extra 38 PSI boost depending on the demand
• The pump will continue to run until the demand drops below 0.7 GPM
• If the main supply fails, the pump will stop.
• It will restart by itself when the city water pressure returns provided the flow is over 1.2 GPM
