In this video
After the clog has cleared and the initial water has drained, confirm that the issue is resolved. Turn on the garbage disposal and run more water from the faucet into both sink basins. Watch to ensure the water drains quickly and smoothly without any gurgling sounds or backups, which verifies that the drain is now clear.
Goal: Confirm the drain is fully unclogged

FAQs
What are the critical safety precautions I must take before climbing onto my roof to clear a vent stack?
Always prioritize safety by wearing appropriate slip-resistant work boots (e.g., Ace Redrock, Shoes For Crews options) and sturdy work gloves. Ensure your ladder is stable on level ground and extends at least 3 feet above the roofline. Never work on a wet, icy, or excessively hot roof, and ideally have a spotter for assistance.
Do I need all the specific tools listed, or are there essential alternatives for clearing a vent stack?
The most essential tools are a durable garden hose (like the GardenJoy Expandable or Pocket Hose Silver Bullet) and a reliable drain auger (The Plumber's Choice 25 ft. Drum Auger) for stubborn clogs. A good flashlight (Panther Vision FLATEYE) is crucial for inspection, and always use proper safety footwear and gloves.
Given this project's "intermediate" difficulty and 6-hour estimate, what should a DIYer know before starting?
The "intermediate" rating mainly stems from working on a roof, which requires confidence and careful attention to safety. While 6 hours is an estimate, factor in time for safety setup, multiple attempts if the clog is stubborn, and a thorough final flush. Don't rush, especially when working at heights.
What should I do if flushing with a garden hose doesn't dislodge the clog from the vent stack?
If water isn't enough, it's time to use The Plumber's Choice 25 ft. Drum Auger. Carefully feed the auger down the vent pipe until you hit the obstruction, then work it back and forth to break up the clog. If the auger also fails, the blockage might be further down or require professional intervention.
