Abstract
A water saving valve is provided for attachment between a water supply pipe and a showerhead. The water saving valve has a spool fitted in a bore defined by first and second walls having first and second openings, respectively. The first and second walls separate the bore from a pipe passageway and a showerhead passageway, respectively. A circumferentially recessed groove is provided in a central portion of the spool, the recessed groove defined by a core which has a diameter approximately 80% of the diameter of the spool. The core has a valve passageway which, when the spool is fitted in the bore in a first portion, substantially horizontally aligns with the first and second openings to allow water to flow unrestricted therethrough. The spool may be rotated by a handle to different positions to regulate the quantity of water allowed to flow through the showerhead.
