Repairing Grundfos Booster Pumps

How we repair your Grundfos Booster Pump
A booster pump raises low household water pressure by drawing from the supply and pushing water through the plumbing at a higher pressure. A booster pump uses an electric motor driving an impeller, a float or pressure switch that turns it on and off, check valves, and a power supply. A technician tests switches, motor and capacitor, and checks valves and piping.
