Clearing a drainage block, especially in an outdoor gully, can often be effectively achieved through persistent and vigorous plunging. This method focuses on dislodging the obstruction to restore proper flow.
The Plunging Method for Drainage Blocks
When faced with a blocked drain or gully, a plunger is a primary tool used to create suction and pressure that can break apart or move the blockage. The key to success lies in consistent and forceful application.
Steps for Effective Plunging
To effectively clear a block using a plunger, particularly in an outside gully:
- Position the Plunger: Ensure the plunger completely covers the drain opening, creating a tight seal.
- Pump Vigorously: Begin pumping the plunger up and down with strong, consistent force. The goal is to create significant hydraulic pressure to push the blockage through.
- Maintain Persistence: Do not give up. Continue pumping vigorously around the drain opening. Clearing stubborn blocks often requires sustained effort.
- Keep Plunging: As highlighted in the provided reference, the action is to "just keep plunging." This persistence is crucial until you observe signs of the blockage clearing.
What to Expect When Clearing a Block
During the plunging process, particularly for heavily blocked gullies, you should anticipate certain outcomes as the obstruction is dislodged:
| Outcome | Description |
|---|---|
| Black Ooze | Expect a "black ooze" or a "stinking horrible mess" to come out of your gully. This is a positive sign, indicating that the accumulated debris, grease, and other material forming the block are being forced out and the drain is beginning to clear. |
Successfully clearing the block typically results in this unsightly but welcome discharge, confirming that the drain's flow is being restored.
