Abstract:
1. Method of installing a sprinkler head location indicator, the method comprising the steps of: providing a sprinkler head shaft wherein the shaft includes an annular collar at its upper end and a telescopic pop-up sprinkler head therein; providing a sprinkler head location indicator, the indicator including a dish having a continuous upper face and a continuous lower face, the upper face and the lower face each having a lower end and an upper end, the indicator being fabricated from a flexible material, a pilot hole extending through a center of the dish at the lower ends of the faces, a plurality of radially-extending guidelines defined on the lower end of the lower face, each of said plurality of guidelines having one end located at the pilot hole and its other end located intermediate the pilot hole and the upper end of the upper face, and a plurality of hash marks defined at intervals on the guidelines to form scale markings for severing the guidelines to uniform length; measuring the diameter of the sprinkler head shaft; severing each of the plurality of radially extending guidelines to a hash mark approximating the measured shaft diameter thereby creating a plurality of flexible tabs for retaining the indicator on the shaft; inserting the sprinkler shaft through the pilot hole, thereby allowing the tabs to remain snug against the shaft; and pulling the indicator upwardly into contact with the annular collar.
