2. Cut a hole in the drywall or ceiling. The hole should be large enough to fit the vent pipe.
3. Install the vent pipe. The vent pipe should be made of PVC or ABS plastic. It should be a minimum of 1.5 inches in diameter. The pipe should be installed with a slope of 1/4 inch per foot towards the vent stack.
4. Seal the vent pipe. The vent pipe should be sealed to the drywall or ceiling with a sealant that is compatible with PVC or ABS plastic.
5. Connect the vent pipe to the vent stack. The vent pipe should be connected to the vent stack with a coupling or adapter.

You can do this by pouring water down the bathtub drain and listening for the water to gurgle up the vent pipe. If you do not hear the water gurgling, the vent pipe is not working properly and you will need to troubleshoot the problem.
