ABSTRACT:
A side ingress water supply conduit arrangement for use with a height adjustable riser for a sprinkler head that reduces labor required for installation of the water supply conduit. The housing of a height adjustable riser is modified to include an integrally molded conduit, which delivers pressurized water to the bottom of an adjustable riser housing by introducing the water supply to the housing via the side of the housing. This allows the conduit to be located closer to the surface of the ground by installing conduits in a shallow burial location slightly below the top of the riser housing. Therefore, less earth removal and replacement is required, which reduces the labor necessary to install a sprinkler system. Another embodiment creates a modified conduit or tube shape, such as a “J” that works with the individual components of the adjustable riser as disclosed in my U.S. Pat. No. 6,629,648.
