A drainage device for an above-ground pool, and an above-ground pool including the drainage device are provided. The drainage device includes a drainage pipe, with inlet and outlet ends, and a drainage valve connected to the inlet end of the drainage pipe. The drainage valve includes a water inlet periphery, defining a water inlet in fluid communication with the inlet end of the drainage pipe, and a connecting member disposed circumferentially around the water inlet periphery. The connecting member is radially spaced apart from the water inlet periphery. The connecting member may be formed by injection molding around the water inlet periphery.

A pin member of threaded connection includes a body and a male thread positioned on the body. The male thread includes a male thread principal portion, a male thread transition portion with a cross-sectional area that is smaller than a cross-sectional area of the male thread principal portion, and a male thread protrusion with a cross-sectional area that is larger than the cross-sectional area of the male thread transition portion with the male thread transition portion positioned between the male thread principal portion and the male thread protrusion.

An assembly is provided that includes a slider seal having a washer and a tubular puck. The washer includes an inner washer surface and an outer washer surface. The inner washer surface extends around an axis of the slider seal and has a non-circular cross-sectional geometry. The inner washer surface forms a washer bore axially through the washer. The outer washer surface extends around the axis and has a cross-sectional geometry with a shape that is different than a shape of the non-circular cross-sectional geometry. The tubular puck projects axially through the washer bore and includes an outer puck surface. The outer puck surface extends around the axis. The outer puck surface is sealingly engaged with and configured to slide axially along the inner washer surface.

In a connector for a fluid line having a connector housing which has a fluid duct extending away from a first opening, a locking device having a locking housing and a locking element is provided in the region of the first opening. The locking housing encloses the connector housing with respect to the fluid duct such that an annular gap which is intended for receiving a substantially cylindrical connection piece is formed between the connector housing and the locking housing. The locking housing has a cutout through which the locking element projects into the annular gap by way of a respective holding portion.

Systems and devices for use in delivery of water to areas of land. The systems include quick coupling valves, quick coupling valve keys, and fluid delivery systems that utilize quick coupling valves and quick coupling valve keys.

A push-to-connect fitting is provided. The push-to-connect fitting includes a connector body, a sealing member, a grab ring, a cartridge, a retainer sleeve, a plurality of latches, and an interference portion. The sealing member is configured to form a sealing engagement with a fluid conduit. The grab ring includes a plurality of teeth configured for coupling to the fluid conduit. The retainer sleeve is received over at least part of the cartridge and is received over at least part of the connector body. The plurality of latches are located on the retainer sleeve and are configured to secure the retainer sleeve to the connector body to facilitate retention of the sealing member, the grab ring, and the cartridge. The interference portion is configured to engage the retainer sleeve to substantially prevent rotation of the retainer sleeve relative to the connector body.

A containment sleeve for use with a pressurized piping system including a pliable fabric sheet having first and second opposing longitudinal edges, first and second opposing transverse edges, and first and second opposing major surfaces respectively defining an interior and exterior surfaces. At least one pleat extends between the first and second transverse edges, the pleat being in a normally closed position to define the interior surface with a first surface area. The sheet of pliable fabric to secure about a portion of a pressurized piping system with the interior major surface facing the pipe so as to form a sleeve having an initial interior volume there about. In response to a rupture of the pressurized piping system within the interior volume, the pleat to expand to an open position to expand the interior surface to a second surface area to increase the interior volume from the initial volume.
