A polymeric riser cap member includes a central tubular section defining a generally cylindrical bore for receiving a sprinkler riser, the central tubular section having open top and bottom ends, and an annular skirt coaxial with the central tubular section and having an inner diameter larger than an inner diameter of the central tubular section. The annular skirt has an inner surface having internal threads threadably connectable with the externally threaded surface of a tubular riser adapter member of a tubular coupler. The bottom end of the central tubular section has an annular projection disposed opposite and spaced from a portion of the annular skirt. The riser cap member includes an annular recess adapted to receive a seal located in a wall extending laterally between the annular skirt and the annular projection.

A multi-fitting rotatable fluid connection apparatus comprising a fluid entry fitting and first and second fluid discharge fittings. The fluid entry fitting comprises a first end connector threaded for attachment to a fluid source, and first and second distribution connectors. The first fluid discharge fitting has a first intake connector which receives fluid from the first distribution connector. A first rotation member is coupled between the first intake connector and the first distribution connector such that the first fluid discharge fitting is rotatable about a first axis of rotation. The second fluid discharge fitting has a second intake connector which receives fluid from the second distribution connector. A second rotation member is coupled between the second intake connector and the second distribution connector such that the second fluid discharge fitting is rotatable about a second axis of rotation.

A toilet assembly includes a toilet, a non-vitreous fluid delivery component, and a connector assembly. The non-vitreous fluid delivery component is coupled to, and in fluid communication with, the toilet. The connector assembly couples the non-vitreous fluid delivery component to the toilet in a substantially watertight manner. The connector assembly includes a connector body, a nut adjustably coupled to the connector body, and a sealing member disposed on the connector body. The nut is configured to be adjusted relative to the connector body to cause the connector body to compress the sealing member against a portion of the toilet, such that the sealing member creates a substantially watertight seal between the toilet and the connector body.

A spout member for attachment to an outer side of a drip irrigation pip has a lower side arranged to attach the pipe. The lower side of the spout member includes at least one rib for facilitating its attachment, where attachment may be to an irrigation pipe, possibly a drip irrigation pipe.

Non-metallic conduit hubs are provided herein, having a flange configured for attachment to an electrical box, a receiving member extending from a first side of the flange and defining a bore sized for receiving a conduit, an indexing indicator extending radially outward from the receiving member for providing a tactile indication of an orientation of the conduit hub, and an alignment member extending from a second side of the flange and having an outer diameter sized for insertion into an ingress/egress port of the electrical box, wherein the bore extends through the receiving member, the flange, and the alignment member to facilitate routing of wires from the conduit into the electrical box.

An isolation valve unit with a fusion outlet including a valve body comprised of a metal, such as brass, and having at least two ports, at least one of the ports including an overmolded thermoplastic end surrounding and enclosing the port from which the fusion outlet extends. In one embodiment, the thermoplastic end is composed of a PP-RCT material and is securely formed over the port by way of an over molding technique. The valve unit further includes a ball valve accommodated within the valve body and a handle for actuating the ball valve. The isolation valve unit is configured to couple to a larger polymeric pipe and to control the flow of fluids in a plumbing system via actuation of the ball valve.
