(57) Abstract :
A bypass valve has a body with an inlet for receiving untreated water, an untte~tetI~ water outlet for connection to a water treatment
apparatus, a treated water inlet and an outlet through which treated water flows. The body includes a first valve seat between the inlet
and the outlet, a second valve seat between the treated water inlet and the outlet, and a third valve seat in a flow path between the inlet
and the outlet. A set of first, second and third flapper valve elements selectively engage and disengage the first, second and third valve
seats respectively. The three flapper valve elements are preferably connected to a common manually operable actuator which can be
latched to hold the valve elements in different functional positions.
