To properly install a toilet roof vent in your home, follow these steps: Determine the location on the roof where the vent will be installed. Cut a hole in the roof for the vent pipe to pass through. Install the vent pipe through the hole, ensuring it is securely attached. Connect the vent pipe to the toilet drain pipe using appropriate fittings. Seal around the vent pipe and roof opening to prevent leaks. Test the vent to ensure proper ventilation.
