The vent pipe is a part of your home’s plumbing system that does not carry water. Instead, it equalises air pressure in the DWV system and release any sewer gases to the air. When a vent pipe gets clogged, you normally have to scale the roof to sort it out, but there is a way to fix it from inside your home. Here’s how:
1. From the ground, check the roof, particularly the chimneys, to find out the approximate position of the vent pipe inside the home.
2. Once you have found the approximate location of the vent pipe, get into the attic and find the pipe as it passes there.
3. Using a hacksaw, cut out a part of the vent.
4. Insert the business end of the auger into the pipe, and then crank the handle clockwise so the cable can go deep into the pipe to break up the clog.
5. Once the clog has been dislodged, crank the handle to the left to retract the cable. If needed, do steps three to five in other parts of the vent pipe.
6. Measure the gap which now has to be closed using tape measure. Make sure that you measure from one end to the next of the open area. Also, measure the diameter of the pipe.
7. With the use of a utility knife, scrape the end parts of the knife to remove the burrs.
8. Have PVC glue applied to the open ends of the pipe as well as the two ends of a coupling. Be sure of having a coupling with exactly the same diameter with the vent pipe. It should also be of the correct length so the open distance will be sealed.
9. Place the coupling in the vent pipe.
When doing this task, make sure that you use a coupling with a threaded cleanout. Also, make sure that you have a plug installed onto the cleanout. This can help you easily access the vent pipe, as you only have to take out the plug of the cleanout and insert the drain snake cable inside.
Also, while you do this task, you may encounter problems with other parts of your plumbing system. For any issues you cannot handle, call a plumbing company right away. Plumbing companies can handle a wide range of issues due to having trained personnel and the right equipment.
