Abstract

The present invention relates to an improvement in jet bath massaging or hydromassaging apparatus (especially therapeutic bath), which is provided with a plurality of openings connected to air ducts, positionned below a level of water and allowing a pressurized flow of air to bubble into water. The improvement is to mount a check valve across each openings in order to prevent any introduction of water into air ducts. The invention also relates to a check valve especially adapted to embody such an improved hydromassaging apparatus.
