A self-contained well water system is designed to be interposed between an external well pump and a plumbing system of a building. The system requires an installer or building owner to make only three basic connections for fully-functional operation: a single water inlet connection from the well pump to the well water system, a single water outlet connection from the well water system to a main input line of the building plumbing system, and a single power connection to provide electrical power to the electrical components of the system, and may also distribute power out to the well pump.

A valve body for a water softener system includes a controller, a seal assembly, and a reciprocating piston driven by a drive mechanism. The controller sends signals to the drive mechanism which moves the piston into various positions. The piston cooperates with the seal assembly to direct the flow of liquid through various flow paths, allowing for water softening and regeneration. During regeneration, a regenerant mixture is directed to flow through a resin bed. The valve body is configurable to perform the regeneration process either through a down-flow configuration, wherein a removable filter is coupled to the valve body in a first orientation and a removable brine injector is installed in a first orifice in the valve body or through an up-flow configuration wherein the removable filter is in a second orientation and the removable brine injector is installed in a second orifice.

A multistage submersible pump includes interstage sealing operable to inhibit upstream fluid recirculation, while also having a reduced or eliminated wear-in procedure. A wear-in bearing surface erodes during an initial, wear-in procedure of the pump, and a low-friction service bearing surface slowly engages as the wear-in procedure is completed. Both the wear-in and service bearing surfaces are integrated into a single, stamped stainless steel housing component, such that axial tolerance between the two surfaces is tightly controllable. The pump impeller provides corresponding wear-in and service bearing elements formed as part of a single monolithic component, thereby also offering tight axial tolerance control for the bearing elements which engage the bearing surfaces of the cup component. During initial operation of the pump, only a small portion of the wear-in bearing element is required to wear down to allow engagement of the service bearing element, thereby minimizing the required time to achieve optimal pump performance and enabling the use of a wide range of materials for the pump impeller.
