A system and method for installing and removing a flow restrictor assembly in a shower, while prevents tampering with the flow restriction system thus installed. Tampering is prevented by concealing the flow restrictor assembly behind a shower wall, attached directly to a water supply line. The system further prevents tampering by concealing the tool-hole necessary for its removal behind a flow restrictor disk, so that there are no visible means of removing the flow restrictor assembly. The flow restrictor assembly threads onto a showerhead arm and the flow restrictor assembly with the attached showerhead arm threads directly into the water line. When the showerhead arm is unthreaded, the flow restrictor assembly remains connected to the water line by an external screw thread. The flow restrictor must be removed to reveal the tool-hole which may only then be engaged by a tool for removal.

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; andinserting 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. 2. The Method as recited in claim 1, wherein the tool-hole is hexagonal in shape, and wherein the tool is a hex key. 3. The method as in claim 2, wherein the flow restrictor disk is mounted with an o-ring, and wherein the step of removing the restrictor disk further comprises prying out the O-ring and flow restrictor. 4. A tamper-resistant flow restrictor assembly, for restricting water flow from a water supply line, through a showerhead and showerhead arm, comprising: a fitting substantially tubular in shape having a first end, a second end, the first end externally threaded for connecting to the water supply line, the second end internally threaded for attaching to the showerhead arm, the second end having substantially no flat surfaces that would allow a tool to grab and rotate the fitting, the first end having a tool-hole having at least one flat surface for allowing a tool to be inserted into the second end, towards the first end to engage the tool-hole, for allowing the fitting to be rotated so that it may be unthreaded and removed; anda flow restrictor disk located within the fitting midway between the first end and second end, the flow restrictor disk blocking view of the tool-hole from the second end, and thereby preventing a user from reaching or even seeing the tool-hole without removing the flow restrictor disk, yet allowing authorized users to easily reach the tool-hole by removing the flow restrictor disk. 5. The flow restrictor assembly as described in claim 1 wherein the at least one flat surface of the tool-hole further comprises a hexagonal opening, so that the tool-hole can be engaged with a hex key to rotate and remove the flow restrictor.
