Rough plumbing of a bathroom requires the installation of a vent pipe. A vent pipe allows fumes, odors and gases to escape and vent outside. Sewer pipes or drain pipes, such as those for a toilet, need a vent pipe to decrease back pressure and allow water to drain away adequately. Installing a sewer vent pipe requires a diagram of where the pipe will be routed to the outside of your home.
Things You'll Need
- Felt tip marker
- PVC tee fitting
- PVC primer
- PVC glue
- Power drill
- PVC connector
- PVC pipe
Determine the location for the vent pipe, on the drain pipe for the toilet. This should be at least 18 inches above a finished floor. Mark the location for the vent tube using the felt tip marker.
Cut the PVC pipe on the mark with the hacksaw. Sand the cut ends of the pipe with sandpaper. This is to remove any burrs from the cut ends of the pipe.
Apply PVC primer to the inside ends of the tee fitting and the outside of the cut ends of pipe, using the applicator. Apply the PVC glue to the inside ends of the tee fitting and to the outside of the cut ends of pipe.
Insert the tee fitting over the cut ends of pipe to reconnect the two ends together. Allow a minimum of 15 minutes for the PVC glue to dry.
Determine where you want the vent pipe to exit the outside of your house. Dill a hole through the roof or wall that is the diameter of the PVC pipe with the power drill.
Insert a PVC connector into the hole from the outside. Attach the PVC pipe to the open end of the tee fitting and then run the pipe to the PVC connector. Secure the sections of PVC together using the PVC glue.
Tips & Warnings
- Connect vent pipes for additional sewer or drain pipes to the existing vent pipe or run additional vent pipes to the outside of your house.
- Vent pipes need to have at least a 45 degree angle to allow gases to vent properly.
- The vent pipe should be no smaller than 1 1/4 inches in diameter.
