To remove a pipe cleanout plug, you typically use a wrench or specialized tool to turn it counterclockwise. If the plug is stuck, you may need to employ additional methods like using a hammer and chisel as described in the provided reference.
Cleanout plugs are essential access points in your plumbing system, allowing for inspections and clog removal. Over time, they can become seized due to rust, corrosion, or debris buildup. Removing a stubborn plug requires the right tools and technique.
Basic Steps for Removing a Cleanout Plug
Before tackling a stuck plug, try the standard method:
- Identify the Plug Type: Cleanout plugs come in various materials (PVC, ABS, cast iron, brass) and designs (recessed square, external nut, or threaded cap).
- Gather Tools: You'll likely need a pipe wrench, adjustable wrench, or specific cleanout wrench that fits the plug's shape. For leverage on external nuts, a large adjustable wrench or basin wrench might work.
- Apply Lubricant: Spray a penetrating lubricant (like WD-40 or a dedicated rust penetrant) around the threads where the plug meets the fitting. Let it sit for 15-30 minutes or longer.
- Attempt to Unscrew: Fit the appropriate wrench onto the plug. Turn the wrench counterclockwise to loosen the plug. Use steady pressure, but avoid excessive force that could damage the pipe or fitting.
Tools You Might Need
| Tool | Purpose | Notes |
|---|---|---|
| Pipe Wrench | Gripping and turning round pipes/fittings | Ideal for many cleanout plug types |
| Adjustable Wrench | Turning hex nuts or square heads | Useful for plugs with external nuts/heads |
| Penetrating Oil | Loosening rust and seized threads | Apply generously and let it soak |
| Rags | Cleaning up debris or leaks | Keep area clean |
Dealing with a Stuck Cleanout Plug
If the plug won't budge with a wrench after applying lubricant, you may need to use more persuasive techniques. One effective method, as detailed in the reference, involves using a hammer and chisel.
According to the reference:
If the plug remains stubborn, place a cold chisel on one edge of the nut and tap it firmly counterclockwise with a ball-peen hammer. Then move to the next face. Continue hammering until the stuck cleanout plug is loose enough to turn with a wrench.
Here's how to apply this method:
- Position the Chisel: Place the tip of a cold chisel against one of the flat edges (or a raised lip if it's not a hex nut) of the cleanout plug, near the outer edge. Angle the chisel slightly so that tapping it will impart a rotational force in the counterclockwise direction.
- Tap with Hammer: Using a ball-peen hammer or a similar metal-faced hammer, tap the end of the chisel firmly. The goal is to create vibrations and apply shock to break the bond of rust or debris holding the plug in place.
- Work Around the Plug: Move the chisel to the next adjacent edge (or spot) on the plug and repeat the tapping process. Continue working your way around the plug, tapping each accessible edge or point in a sequence.
- Re-Attempt with Wrench: After several rounds of tapping, try using your wrench again. The percussive force from the hammer and chisel may have loosened the threads sufficiently.
- Repeat if Necessary: If the plug still doesn't turn, repeat the hammer and chisel process. You may need to tap more firmly or soak the plug again with penetrating oil.
Important Considerations:
- Safety First: Wear safety glasses to protect your eyes from debris. Be cautious when swinging a hammer.
- Material Matters: This hammer and chisel method is generally safer for metal plugs (cast iron, brass). Be extremely careful or avoid this method on plastic (PVC, ABS) plugs or fittings, as they can easily crack or break.
- Access: Ensure you have adequate space to swing the hammer and position the chisel safely.
- Drainage: Be prepared for potential water or sewage to drain out once the plug is removed, especially if you're opening a main line or a line with a blockage. Have buckets and rags ready.
By combining the standard wrench method with techniques like using penetrating oil and the hammer-and-chisel method for stuck plugs, you can effectively remove most pipe cleanout plugs.
