A spray head body extension that is screwed onto the upper end of a spray head body after the cap is removed. The cap is then reinstalled on the extension to raise the effective height of the a spray head body and its spray pattern. The spray head body extension permits fast, easy raising of a sunken in-ground spray head without having to dig below the spray head's water supply. A one-piece embodiment uses a compressible gasket to enable the extension to be tightened to the body until the internal guide splines of both the extension and body are aligned. A set screw can be employed to preserve alignment when the cap is reinstalled. An alignment tool helps align the splines of the extension to the body during installation. A multi-piece embodiment enables the extension to be aligned to the body before a separate collar nut is tightened.

An improved protective housing assembly for a pop-up type in-ground sprinkler incorporates one or more spacer disks, configured for being seated beneath a sprinkler support housing body flange, extend(s) outwardly to effectively prevent grass and other ground cover from extending over the in-ground pop-up sprinkler. An optional unitary porous filter disk body may be provided sized, shaped and otherwise configured for being snugly received within the sprinkler support housing interior space, and includes a central opening for snugly receiving the sprinkler main body therethrough, such that the porous structure of the filter disk body enables passage of water therethrough while preventing passage of solid debris into the bottom of the sprinkler support housing body.

Implementations of a decorative rotating lawn sprinkler are provided. In some implementations, the decorative rotating lawn sprinkler comprises a rotating sprinkler head, a figurine, piping, and a support.

In some implementations, an example method of use of the decorative rotating lawn sprinkler comprises anchoring or otherwise supporting the decorative rotating lawn sprinkler on a lawn or other surface, connecting the decorative rotating lawn sprinkler to a water source, and operating the decorative rotating lawn sprinkler to disperse water from the connected water source over a circular or semi-circular area of the lawn or other vegetation.

An assembly for replacing sprinkler heads includes a sprinkler head housing assembly with a cap, a sprinkler head, a sprinkler head support assembly core, a plurality of spacers, and a base. The sprinkler head housing assembly enables replacement of a damaged inground sprinkler head.

A valve includes an inlet and an outlet, a body including a first seat and a second seat, wherein the first seat and second seat are spaced apart from each other at a predetermined distance, a cavity in the body, a piston positioned in the cavity, wherein the piston rests against the first seat and the second seat when in the closed position, and a pilot ball adjacent the piston.

An adjustable height connection for water irrigation with a base structure, a first pipe, a second pipe and a hose attachment pipe. The first pipe telescopes into the second pipe. The second pipe is attached via a hinge member to the base structure so that it can be folded for compact storage or transport. The hose attachment pipe has a threaded inlet and outlet and is attached perpendicularly to the top of the first pipe. The first pipe includes indentations to allow a treaded locking screw to penetrate the side wall of the second pipe and engage one of the indentations of the first pipe thereby holding it in place. The base structure includes downward facing arrow shaped legs to help secure it to dirt-like ground surface.

An irrigation sprinkler is described. The irrigation sprinkler includes a first ring including a first edge defining a first plurality of semicircular recesses and a second ring including a second edge defining a second plurality of semicircular recesses. The first ring and the second ring are secured together to define a plurality of circular recesses. The first ring includes a fin proximate each circular recess. The irrigation sprinkler also includes an adjustment mechanism disposed within each of the circular recesses. Each adjustment mechanism includes an outer rotating member including an annular structure comprising at least one of an annular recess and an annular protrusion, and an internal chamber including inwardly disposed threads. Each adjustment mechanism also includes an inner cylindrical member including an outer surface. The outer surface defines outwardly disposed threads and a channel. The channel extends radially along only a portion of the inner cylindrical member.
