Abstract: A cooktop drain that heats liquid in a stockpot and empties the hot liquid directly down a drain. The cooktop sits in at countertop level over a sink and a valved stockpot sits on the cooktop. The sink, cooktop and stockpot are assembled such that heating, draining the stockpot of liquid and rinsing any residue are performed by a single apparatus without having to transport and tip the stockpot. The cooktop drain has a burner underneath a grate, and the stockpot has a bottom valve connecting to an integrated funnel leading directly to the sink directly beneath the grate and the drain, bypassing the burner, disposing of heated water directly through the valve and integrated funnel into the sink and down the drain. The cooktop drain has a rinse head in the sink that rinses any food residue a clean, fresh smelling sink under the grate without removing the burner.
