Using a water pipe extractor, often referred to as a pipe nipple extractor or thread remover, is a precise method to remove broken pipe sections or stubborn threads from fittings, allowing for new pipe installation. The core process involves securely engaging the extractor within the broken piece and then rotating it in a counterclockwise direction to unscrew it.
Understanding Pipe Nipple Extractors
A pipe nipple extractor is an essential tool for plumbing repairs, specifically designed to tackle broken pipe sections that are flush or recessed within a fitting. When a pipe nipple or a threaded pipe breaks off inside another fitting, traditional wrenches or pliers become useless. This is where an extractor comes into play, providing the necessary grip and leverage to remove the lodged piece.
When to Use a Pipe Nipple Extractor
You'll typically reach for this tool when:
- A threaded pipe nipple has broken off inside a wall, floor, or another fitting.
- The internal threads of a fitting need to be cleared of a broken piece.
- You need to remove a stubborn, rusted, or corroded pipe section without damaging the surrounding fitting.
Step-by-Step Guide to Using a Water Pipe Extractor
Effectively using a water pipe extractor involves several key steps to ensure safe and successful removal of the broken pipe or thread.
1. Preparation & Safety
Before you begin, ensure the water supply to the affected area is completely shut off. Gather your tools, including the pipe extractor set, a wrench or adjustable spanner, safety glasses, and gloves. Clear the workspace to prevent obstructions.
2. Selecting the Correct Extractor Size
Pipe extractors come in various sizes, each designed for specific pipe diameters. It's crucial to select an extractor that fits snugly into the broken pipe's inner diameter. A proper fit ensures maximum grip and prevents slipping, which could further damage the pipe or fitting.
3. Inserting the Extractor
Carefully insert the correctly sized extractor into the internal bore of the broken pipe or thread. For best results, ensure the extractor goes in as deep as possible without forcing it. Some extractors have tapered, self-biting designs.
4. Engaging the Extractor
Once inserted, you may need to gently tap the extractor with a hammer to ensure its tapered, fluted, or spiral design bites firmly into the soft metal of the broken pipe. This creates a secure, non-slip grip necessary for the removal process. Ensure it's seated firmly and not wobbling.
5. Removing the Broken Thread
This is the critical step where the broken piece is unscrewed. Attach an appropriate wrench (e.g., a pipe wrench, adjustable spanner, or a ratcheting wrench, depending on the extractor's design) to the extractor's square or hex head.
As highlighted in the reference, "wrench it out in a counterclockwise motion." Apply steady, firm pressure to turn the wrench counterclockwise. This motion is crucial because most pipe threads are right-hand threads, meaning they tighten clockwise and loosen counterclockwise. As you turn, the extractor's design will grip tighter into the broken pipe, allowing it to unscrew from the fitting. Continue turning until the broken thread is completely removed.
6. Final Inspection
Once the broken pipe or thread is removed, inspect the internal threads of the fitting to ensure they are clean and undamaged. This prepares the fitting for a new pipe or nipple installation. As the reference states, "And there you have it the threat is removed ready to replace your pipe."
Tips for Success
- Lubrication: For stubborn or corroded pipes, apply penetrating oil to the threads and let it sit for a few minutes before attempting removal.
- Heat (Use Caution): In extreme cases of rust, a little heat applied to the outside of the fitting (not the broken pipe itself) can help expand the fitting slightly, making removal easier. Always use caution with heat and flammable materials.
- Don't Force It: If the extractor slips or doesn't turn, re-evaluate your size selection or the engagement. Forcing it can strip the extractor or further damage the fitting.
- Clean Threads: After removal, clean the internal threads of the fitting with a wire brush or thread tap if necessary, to ensure a good seal with the new pipe.
