1. A multi-functional valve including a housing and piston member, and having a combined safety, bypass, shut-off and inservice capability to be applied to a water treatment system, wherein:

  • a. said housing has a base member and a head portion;

    b. said base member includes a securing means for securing said valve to a cylinder;

    c. said cylinder forms a part of said water treatment system;

    d. said piston member includes a sealing mechanism capable of operably cooperating with said housing;

    e. said piston member has a shut-off position, a filtered position and an unfiltered position;

    f. said piston member is movably mounted within said housing;

    g. a lever is operably connected to said piston member;

    h. said lever is situated exterior in relation to said housing;

    i. said piston includes a wall;

    j. said sealing mechanism includes at least one member encircling said piston member and at least one member mounted in said wall;

    k. said base member includes an inlet and an outlet;

    l. said head portion includes a water receiving section capable of being tapped directly into a waterline;

    m. said piston member has a filtered position, a bypass position, and a closed position;

    n. said piston member is actuated by a single lever;

    o. said water receiving section includes a headtube tappable directly into a waterline;

    p. said head portion includes a piston aperture to receive said piston member;

    q. said piston aperture substantially terminates at said base member;

    r. an operating means is secured to said piston member;

    s. said headtube, said base base inlet and said base outlet may communicate;

    t. said piston member changes communication of said headtube, said base base inlet and said base outlet by moving through said filtered position, said bypass position, and said closed position;

    u. said filtered position blocks water flow through said headtube and permits water to flow through said cylinder;

    v. said unfiltered position blocks passage of water into said cylinder and permits complete by-pass of said cylinder;

    w. said closed position cuts off water flow;

    x. said headtube includes a first headtube end to receive said incoming water by being secured to a first cut end of a main water line;

    y. said headtube includes a second headtube end to receive a second cut end of a main water line;

    z. said headtube end and said headtube end serve to connect said valve to said main waterline and close said main waterline;

    aa. said cylinder includes an axial outlet tube;

    ab. said axial outlet tube is coaxial with said base unit;

    ac. said piston member is of a generally cylindrical shape;

    ad. said piston member has a base fitting into said piston aperture;

    ae. said base includes a concave central portion;

    af. said piston member includes a handle top oppositely disposed from said concave central portion;

    ag. said handle top includes a first end portion of a lever; and

    ah. said lever is operably secured to said piston member.
