Step 6 · Verify the Clog is Cleared
After you believe the clog has been cleared with the auger, you must verify your work. Use the garden hose again to flush the vent pipe thoroughly with water for a few minutes. This will wash away any remaining debris. While you are flushing the pipe, have your helper inside the house run the faucets in the sinks and tubs and flush the toilets that were previously draining slowly. They should confirm that the drains are now flowing quickly and freely, and that any gurgling noises have stopped. This confirmation is crucial before you clean up and leave the roof.
