The container includes a divider which extends from an open top end toward a closed bottom end, the divider spaced apart from the closed bottom end to define an opening and separating the container into a first fluid path on a first side of the divider through which fluid can enter the container through the inlet port and a second fluid path on a second side of the divider through which fluid can enter the opening and exit the container through the outlet port. The second fluid path includes at least one filter between the opening and the open top end through which fluid can pass from the first fluid path to the second fluid path but through which at least one component of the injectate cannot pass.

Abstract: A valve arrangement includes various improvements useable in the context of a fluid additive system, such as a water softener. For example, the valve assembly may include a seal assembly engaged by a reciprocating piston, in which the seal assembly includes a minimal number of parts, is easily assembled, and can be easily inserted in the bore of the valve body without jeopardizing the integrity of the seals. The valve assembly may further include a quick-disconnect system which allows a “control head” including a valve actuation system and electronic controls to be disconnected from the rest of the valve arrangement with only a partial rotation of the control head.

Abstract: A liquid transfer device is disclosed that has a fluid pump enclosed within a rigid, space enclosing housing. The pump has a strainer with strainer openings that provide a fluid connection between the pump and the inside of the housing. The strainer is located at the lower end of the pump and the housing.
