Coupling apparatus for a floor drain and method of use

A method of coupling a hot water tank to a floor drain, comprising:

• providing a coupling apparatus for a floor drain, comprising:
• a hollow body having an exterior surface and an interior surface, the interior surface defining a flow chamber;
• a primary inlet through the exterior surface of the body into the flow chamber, the primary inlet being of a first size to accommodate a drainage line from a hot water tank;
• at least one secondary inlet through the exterior surface of the body into the flow chamber, each secondary inlet being of a second size smaller than the primary inlet in order to accommodate a smaller drainage line;
• and
• a single outlet through the exterior surface of the body for draining the flow chamber;
• connecting the outlet to a floor drain;
• connecting the primary inlet to a drainage line for a hot water tank;
• connecting the at least one secondary inlet to a drainage line from one of a humidifier, a furnace, an air handler or an air conditioner.

A coupling apparatus for a floor drain, comprising:

• a hollow body having an exterior surface and an interior surface, the interior surface defining a flow chamber;
• a primary inlet through the exterior surface of the body into the flow chamber, the primary inlet being of a first size to accommodate a drainage line from a hot water tank, a pipe coupling for the primary inlet protrudes outwardly from the body;
• three secondary inlets through the exterior surface of the body into the flow chamber, each secondary inlet being of a second size smaller than the primary inlet in order to accommodate a smaller drainage line, each secondary inlet having a pipe coupling that protrudes outwardly from the body;
• and
• a single outlet through the exterior surface of the body for draining the flow chamber, the outlet having a pipe coupling that protrudes outwardly from the body, the pipe coupling for the outlet having a circumferential floor engaging flange with drainage holes, the outlet and flow chamber form a hub with the flow chamber positioned above the outlet and with the primary inlet and the three secondary inlets extending radially from the hub.
