A pressurized closure assembly is provided which has a connector assembly to allow improved application of torque in limited space conditions to rotate a head away from the hub of the closure assembly.

Pressurized closure assembly

A grinder pump basin system is provided which includes a basin; a cover plate; a bracket secured to the cover plate; and a grinder pump with cutter plate with openings and a cutter blade secured to the bracket above a bottom surface of the basin. The openings in the cutter plate have an unique shape which assists in the cutting of material which flows through an inlet of a grinder pump. The shape of the cutter blade cooperates with the openings in the cutter plate such that solids are forced between these respective components and thereby are efficiently cut into small pieces for passing through the openings and for discharge from the grinder pump basin system.

Grinder pump basin system

A sealed and self-contained tankless water heater flushing system including a holding basin, a cover lid for the holding basin firmly securable and sealed liquid tight to the holding basin, a submersible pump contained within the holding basin, a submersible pump hose, securable from the submersible pump within the holding basin to a discharge opening in the cover of the holding basin, a filter system, securable within the holding basin to a filter opening contained in the cover lid, wherein the filter system includes a filter for filtering solid substances from the tankless water heater during a flushing process, a discharge hose for connecting the discharge opening to the water heater, and a filter hose for connecting the filter opening to the water heater.

Sealed and self-contained tankless water heater flushing system

A closure comprises a hub with a central opening and a head pivotally connected to the hub, the head sealing the central opening when in a closed position. A lip seal relief is defined by a stepped surface between the head and the hub so that when the head is closed, the relief or clearance is provided between the head and hub inhibiting damage to a seal.

Closure lip seal relief

A closure comprises a hub with a central opening and a head positionable within the hub, the head sealing the central opening when in a closed position, a spool rotatable about a post extending from the head, wherein rotation of the spool causes axial movement of the spool along the post, a plurality of radial arms extending from the spool to a plurality of locking segments.

Tool-less closure

A grinder pump basin system is provided which includes a basin; a cover plate; a bracket secured to the cover plate; and a grinder pump with cutter plate with openings and a cutter blade secured to the bracket above a bottom surface of the basin. The bracket includes a front portion, which prevents waste water from interacting adversely with the grinder pump when it enters the basin. A discharge system for the grinder pump is secured to an outlet of the grinder pump and includes a discharge pipe and a flexible discharge coupling. Flow directional jets are also provided in an elbow of the pump discharge system to direct waste water and solids away from the grinder pump.

A pump is provided including a cutter plate disposed at a pump inlet including a plurality of holes. Multiple embodiments provide that the pump includes a rotatable cutter blade disposed substantially adjacent to the cutter plate. Embodiments include those wherein the plurality of holes are angled in a direction of rotation of the cutter blade. In some embodiments, the cutter blade has at least one relief hole and at least one cutting edge. Additional embodiments include those wherein a ring extends outward from the pump inlet for channeling material toward the pump inlet in a substantially perpendicular approach with respect to the cutter plate.
