A residential water pressure booster is disclosed comprising a housing with a primary inlet attached to a water source and with an outlet supplying the residential water use. Some of the energy of the flowing water is captured by a turbine impeller that is mounted on a drive shaft. The drive shaft transmits this energy to a pump impeller and, in the preferred embodiment, to a centrifugal pump impeller, both of which boost the pressure of the liquid. Water pressure is also increased by a constriction chamber which constricts the flow between the turbine impeller and the pump impeller. The efficiency of the pump impeller is increased by the action of the centrifugal pump impeller and directional fins and directional grooves in the constriction chamber, which impart a rotational motion to the liquid. The device efficiently boosts water pressure with an external power source.
