Abstract
A pop-up sprinkler assembly includes a cylindrical housing having a cap on an upper end thereof, the cap having an opening, a lower end of the cylindrical housing having an internal thread for attachment to a source of pressurized water. A stem is mounted in the cylindrical housing with a spring radially between the stem and the cylindrical housing for normally biasing the stem to a retracted position within the cylindrical housing. The stem is extendable through the opening in the first cap to an extended position when water under pressure is supplied to the cylindrical housing. The stem has a threaded upper end to which an alternative sprinkler head is attached. An adapter housing is received over the cap and secured to the cylindrical housing, the sprinkler housing having an open upper end, the adapter housing having a diameter sufficient to receive the alternative sprinkler head when the stem is in the retracted position. A cover is secured to an upper end of the sprinkler head and adapted to close the open upper end of the adapter housing when the stem is in the retracted position. A conversion kit for adapting the otherwise incompatible sprinkler head to the pop-up assembly is also provided.
