The current old style dialysis chases were designed and built with casework that houses the solution delivery fluid lines, fittings, additional valves along with the recessed water boxes, and the drain manifold. This stick built system uses standard particle board or plywood covered with plastic laminate or painted. Some clinics use either a ground up or suspended up off the floor design for their casework.

This old style design has been accepted as the standard design. It is just a matter of time when problems with moisture, deterioration, mold and mildew sets in. Add to this the horizontal indirect waste lines create an environment were bio-film build up in the lines cause bacterial growth and unpleasant odors as well as attract pests like drain flies, gnats, vermin and other insects. All of these conditions create an unpleasant and unsafe atmosphere for patients and staff.

George Taweh and his co-designer, Tim Sutton, designed a water box that will face-mount on the wall having the valves included in a single manifold with very few fittings to make the system work with chemical or hot water disinfection.

Instead of a particleboard cabinet, this system has an aesthetically appealing horizontal bumper rail that takes up less room than cabinetry and would house the fluid solution lines keeping them organized.

The drain box is isolated from the T Box manifold, which allows ease of cleaning and disinfection. This drain box also serves as a drip catchment below the T Box manifold. The machine drain connection to the drain box has a built-in air gap for the dialysate discharge line from the dialysis machines.
