How to Diagnose and Fix a Gurgling Toilet · Step 3 of 5
In this video
Every plumbing system has a vent stack, which is a pipe that runs vertically through the walls and out the roof. Its purpose is to allow air into the pipes for proper drainage and to vent sewer gases safely outside. If this vent pipe has a crack or a loose joint within an attic or wall space, sewer gas can leak directly into your home instead of exiting through the roof. Finding such a leak can be difficult and may require a plumber.

FAQs
How difficult is it to fix a gurgling toilet, and how much time should I expect it to take?
This project is rated as "beginner" difficulty. Many issues can be resolved quickly with a plunger. However, if the problem lies in the vent stack, it can become more involved and potentially require roof access. Expect to spend anywhere from 30 minutes to 2 hours, depending on the cause and whether you need to clear the plumbing vent.
What are the essential tools I absolutely need to have before attempting to fix my gurgling toilet?
At a minimum, you'll need a high-quality plunger and heavy-duty gloves. If plunging doesn't work, a drain auger (plumbing snake) is crucial for clearing deeper clogs. For vent stack issues, a sturdy ladder, garden hose with a spray nozzle, and potentially a pipe wrench are also necessary.
What are the most important safety precautions I should take when diagnosing and fixing a gurgling toilet?
Always wear heavy-duty latex gloves and work gloves to protect yourself from unsanitary water and potential chemicals. If accessing the roof to clear the vent stack, use a sturdy ladder placed on level ground, wear slip-resistant shoes, and consider having a spotter. Be cautious when operating a drain auger to prevent injury or pipe damage.
I've plunged my toilet multiple times, but it's still gurgling. What should I try next?
If plunging doesn't resolve the gurgling, the issue is likely a partial blockage further down your main sewer line or, more commonly, in your plumbing vent stack. The next step is to use a drain auger to clear the main line cleanout, or proceed to inspect and clear the plumbing vent from your roof as outlined in the project steps.
