If you're trying to carry out a home improvement project that involves plumbing, you can sometimes run into the problem of not being able to remove a fixture. Your entire project can quickly grind to a halt when you're dealing with a stuck fixture that stubbornly refuses to come off. While you could call in a professional to do this part of your project for you, it is possible to remove badly stuck plumbing fixtures if you have the right tools and are willing to put a lot of effort and elbow grease into the process. The following will show you how to do this.
What You Will Need
Set of Wrenches
Torch Cigar Lighter
Hacksaw with Metal Cutting Hacksaw Blade
Step 1. Use a wrench to tighten the nut or nuts holding the fixture in place. While this might seem counter-intuitive (since your goal is to get them off), the rationale behind this approach is that getting any movement either way will help to loosen the nut so that it can then turn in the other direction and be removed.
Step 2. If trying to rock the nut back and forth with a wrench doesn't work, position a center punch on one of the hexagonal sides of the nut in question (near the middle) and tap the center punch a few times with a hammer to try to jar the nut loose.
Step 3. If it's still not lose, use a small torch cigar lighter (or something similar) to heat up the nut. You don't want to heat up the bolt when you're doing this. Your objective is to raise the temperature of the nut relative to the bolt so that it expands slightly and can be more easily removed. You'll want to quickly use the wrench to remove the nut before it cools and contracts.
Step 4. Apply penetrating oil to the points where the bolt and nut come into contact with each other. It can take some time for this to work, since the oil has to (as the name suggests) penetrate between the bolt and nut. You can be working on other aspects of your project while you're waiting. You might also want to add more oil over the course of the day. Then try again with the wrench.
Step 5. Use a hacksaw to remove the nut and bolt if all else fails. Cut through the threads of the bolt and keep cutting all the way through the nut until you can remove them.
