Kit includes 18″ PVC pipe (4″ interior diameter), a rubber coupling to attach the pipe to the flange on the back of the toilet, a dryer flap to put on the wall at the end of the pipe so that air can’t come back into the toilet, and a 20-amp wall receptacle to match the plug on toilet. Specify 120 or 240 volts.
If you are venting up through the roof or up an outside wall, then you would need more pipe and a rain cap for the end of the vent line. You can snug the PVC pipe onto the flange of the toilet, eliminating the rubber coupling to save space. All components are available locally. Feel free to call us if you have questions about venting.
