연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

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 of installing a flow restrictor assembly for restricting water flow to a showerhead comprising the steps of: removing a shower arm from a water supply line, said shower arm having a proximate end and a distal end, said distal end being attached to said showerhead;providing a flow restrictor assembly, said flow restrictor assembly comprising a fitting and a flow restrictor disk positioned in the interior of said fitting; andinstalling said flow restrictor assembly directly between said proximate end of said shower arm and said water supply line behind a wall;wherein when said water flows from said water supply line into said fitting, said water flows through said restrictor disk disposed within said fitting and to said shower arm; andwherein said fitting comprises a tool-hole opening forming a surface adapted to be engaged by a tool for removing said fitting from said water supply line. 2. The method of claim 1 comprising the step of attaching said flow restrictor assembly to said proximate end of said shower arm before said installing step. 3. The method of claim 1 further comprising the step of concealing the proximate end of the shower arm behind a cover plate after said installing step. 4. A method of installing a flow restrictor assembly for restricting water flow to a showerhead comprising the steps of: removing a shower arm from a water supply line, said shower arm having a proximate end and a distal end, said distal end being attached to said showerhead;providing a flow restrictor assembly, said flow restrictor assembly comprising a fitting and a flow restrictor disk positioned in the interior of said fitting;installing said flow restrictor assembly directly between said proximate end of said shower arm and said water supply line behind a wall;wherein when said water flows from said water supply line into said fitting, said water flows through said restrictor disk disposed within said fitting and to said shower armremoving said fitting from said water supply line, wherein said fitting comprises a tool-hole opening forming a surface adapted to be engaged by a tool for removing said fitting from said water supply line. 5. The method of claim 4, further comprising the step of removing said restrictor disk from said fitting prior to removing said fitting from said water supply line. 6. A method of installing a flow restrictor assembly for restricting water flow to a showerhead comprising the steps of: removing a shower arm from a water supply line, said shower arm having a proximate end and a distal end, said distal end being attached to said showerhead;providing a flow restrictor assembly, said flow restrictor assembly comprising a fitting and a flow restrictor disk positioned in the interior of said fitting;attaching one end of said flow restrictor assembly to said proximate end of said shower arm;installing said flow restrictor assembly between said proximate end of said shower arm and said water supply line, directly to said water supply line behind a wall; andconcealing the proximate end of the shower arm behind a cover plate;wherein when said water flows from said water supply line into said fitting, said water flows through said restrictor disk disposed within said fitting; andwherein said fitting comprises a tool-hole opening forming a surface adapted to be engaged by a tool for removing said fitting from said water supply line. 7. The method of claim 6, wherein said fitting has a bottom section without a flat edge for being engaged by a tool. 8. The method of claim 6, wherein the flow restrictor assembly has a flow restrictor disk that partially covers the tool-hole opening, thereby concealing the mechanism of removing the flow restrictor assembly. 9. A flow restrictor assembly for restricting water flow comprising: a fitting having a top section and a bottom section, said top section having an exterior screw thread and said bottom section having an interior screw thread;a first opening at a first end of said fitting positioned at said top section;a flat plane at said first end, said flat plane incorporating a tool-hole in the shape of a polygon;a second opening at a second end of said fitting positioned at said bottom section, wherein said fitting has a continuous bore for carrying water, said bore being larger at said bottom section than said top section;a flow restrictor disk; andan O-ring, said flow restrictor disk and said O-ring being positioned inside said fitting against a ridge. 10. The flow restrictor assembly of claim 9, wherein said flow restrictor disk and said O-ring are positioned inside the bottom section of said fitting. 11. The flow restrictor assembly of claim 9, wherein when said flow restrictor disk and said O-ring are positioned inside the bottom section of said fitting once installed, the tool-hole is not visible. 12. The flow restrictor assembly of claim 9, wherein said bottom section does not have a flat edge for being engaged by a tool. 13. A flow restrictor assembly for restricting water flow comprising: a fitting having a top section and a bottom section, said top section having an exterior screw thread adapted to be connected directly to a water supply line behind a wall, and said bottom section having an interior screw thread adapted to be connected directly to a shower arm;a first opening at a first end of said fitting positioned at said top section;a flat plane at said first end, said flat plane incorporating a tool-hole in a polygon shape;a second opening at a second end of said fitting positioned at said bottom section, wherein said fitting has a continuous bore for carrying water;a flow restrictor disk; andan O-ring, said flow restrictor disk and said O-ring being positioned inside said fitting against a ridge. 14. The flow restrictor assembly of claim 13, wherein said flow restrictor disk and said O-ring are positioned inside the bottom section of said fitting. 15. The flow restrictor assembly of claim 14, wherein when said flow restrictor disk and said O-ring are positioned inside the bottom section of said fitting once installed, the tool-hole is not visible. 16. The flow restrictor assembly of claim 13, wherein said bottom section does not have a flat edge for being engaged by a tool.
