Abstract: This invention relates to a fluid distribution manifold, where the input piping is inserted in through the manifold's circular intake opening and onto its cylindrical input port. The manifold's intake opening leads through a cylindrical path to a closed terminal end. Along the inner manifold wall, there are arranged in a sequence, which may be in a straight line, a series of straight lines or rows, a spiral, or an alternating 90- or 180-degree arrangement, a number of distribution outlet openings and their respective ports, which may be barbed or ribbed on their outer surface. The manifold has the further utility of being expandable to larger sizes. This is achieved by removing the closed terminal end from one manifold and then inserting and connecting that open terminal end in through another manifold's circular intake opening and into its intake port.

Abstract: A plurality of water injection nozzles (16) are spaced around the tub (12) of a hydrotherapy spa (10) for injecting a pulsating flow of water and air into the main body of water (14) in the tub (12). The pulsation is produced by a distribution valve (30), (80) including rotor (46) , (92) which is rotated by the inlet water flow and distributes the inlet water to outlets (40,42,44), (90) which are connected to the nozzles (16) respectively. The rotor (46), (92) is formed with a groove (48), (96) which sequentially aligns with and connects the outlets (40,42,44), (90) to the inlet (34), (86). Since each outlet (40,42,44), (90) is periodically connected to and disconnected from the inlet (34), (86), the water is supplied to each nozzle (16) in a pulsating or chopped manner. The sequence in which the water is distributed to the nozzles (16) is fixed, enabling a rippling effect to be produced in which the pulsation appears to rotate around the spa (10).

Abstract: A simple yet inexpensive device is presented which is used to divide the water normally supplied to the spill tube and gooseneck reservoir of a commode. Dividing the water supplied to the spill tube and diverting a substantial portion of that water to a holding tank of a commode saves water that is normally unnecessarily fed directly down the drain in the refilling process. The device is a small plastic insert that has a generally rectangular main body. At one end of this main body is a horizontal inlet tube. At the bottom of the main body are a number of lower vertical outlet tubes. In order to evenly disperse the inlet water among the vertical outlet tubes, the upper mouth of the vertical outlet tubes is constricted by narrowing the diameter of the mouth with respect to the inner diameter of the inlet tube. Water is thus distributed evenly among the lower outlet tubes.

The inlet orifice is located between the volume and a source of domestic water. The outlet orifice is located between the volume and a sewer drain trap. The conduit defines a valve seat and, in first position, the valve element engages the seat to restrict flow of water from the water chamber into the conduit.
