Abstract:
1. A method for installing and deinstalling a flow restrictor assembly, while preventing unauthorized tampering, for use with a showerhead having a showerhead arm, and a water line having a threaded opening, the flow restrictor assembly having a fitting with a partially closed first end with a tool-hole, the first end having an external screw thread, the flow restrictor assembly having an open second end, a flow restrictor disk and an O-ring between the first end and second end, comprising the steps of: installing onto the water line by threading the fitting of the flow restrictor assembly onto the showerhead arm and then threading the first end of the fitting into the water line by rotating the showerhead arm; restricting water flow from the water line through the showerhead by restricting water flow through the flow restrictor assembly by the flow restrictor disk; detaching the showerhead arm from the restrictor assembly by unthreading the showerhead arm, leaving the flow restrictor assembly in place attached to the water line; revealing the tool-hole by removing the flow restrictor disk from the flow restrictor assembly; and inserting a tool through the open second end and into the tool-hole and rotating the tool to loosen and remove the fitting from the water line.
