Foot operated stop valve

In combination:

• at least one water supply pipe,
• at least one hand-operated water valve for controlling water flow through said water supply pipe,
• at least one valve means for controlling water flow through said water supply pipe, said valve means being positioned in series with said hand-operated water valve, said valve means having an open position and a closed position,
• a biasing means for biasing said valve means toward said open position,
• a pedal having an on position and an off position,
• a means for connecting said pedal to said valve means such that, when a pressure is applied to said pedal to move said pedal from said on position to said off position, said valve means is urged from said open position to said closed position, and in the absence of a pressure to move said pedal from said on position to said off position, said biasing means urges said valve means from said closed position to said open position.

In combination:

• a hot water supply pipe,
• a hand-operated hot water valve for controlling water flow through said hot water supply pipe,
• a first valve means for controlling water flow through said hot water supply pipe, said first valve means being positioned in series with said hand-operated hot water valve, said first valve means having an open position and a closed position,
• a first biasing means for biasing said first valve means toward said open position,
• a cold water supply pipe,
• a hand-operated cold water valve for controlling water flow through said cold water supply pipe,
• a second valve means for controlling water flow through said cold water supply pipe, said second valve means being positioned in series with said hand-operated cold water valve, said second valve means having an open position and a closed position,
• a second biasing means for biasing said second valve means toward said open position,
• a pedal having an on position and an off position,
• a means for connecting said pedal to said first valve means and said second valve means such that, when a pressure is applied to said pedal to move said pedal from said on position to said off position, said first valve means and said second valve means are urged from said open position to said closed position, and in the absence of a pressure to move said pedal from said on position to said off position, said first biasing means urges said first valve means from said closed position to said open position and said second biasing means urges said second valve means from said closed position to said open position.
