A system for clearing a clog includes a body, for example a sink or toilet, has an interior chamber fluidly connected a sewer or drain field. A wastewater passage has a wastewater valve and a trap therein and an outlet which is fluidly connected through a drain line to the sewer or drain field, the passage opening to the chamber. A pressurized water supply line is provided to selectively discharge water into the chamber. A shunt valve fluidly connects the supply line to the wastewater passage intermediate the wastewater valve and the outlet. During normal use the shunt valve is closed and the wastewater valve is open, however, when a clog occurs, the wastewater valve is closed and the shunt valve is opened to apply water under pressure to clear the clog.
