1. A hydrotherapy device, comprising:

  • water retaining means for retaining a body of water, said means having an outlet and a plurality of inlets;

    injecting means associated with each of said inlets for injecting water into the body of water at a high velocity;

    a water circulating and purifying system including a centrifugal liquid pump and a filter serially connected between the outlet of the water retaining means and the injection means;

    a motor capable of operating at at least two speeds drivably connected to said pump;

    means for selecting one of said two motor speeds whereby a high water circulation rate may be selected when the hydrotherapy device is to be used and a low water circulation rate may be selected during periods of non-use so that the water may be filtered at an energy saving low circulation rate; and

    means associated with said circulation system for selectively bypassing the filter during periods of use and high water circulation rates to thereby cause a greater increase in the water circulation rate and improved therapeutic action.
