Which of the following tools would be used for taking apart old plumbing fixtures?

Using the right tools is crucial when taking apart old plumbing fixtures. An adjustable wrench is versatile and can grip various sizes of nuts and bolts, making it ideal for loosening connections that may have corroded or become stuck over time. Locking pliers are particularly useful for providing a strong grip on fixtures, which can be beneficial when trying to overcome resistance from rust or mineral buildup. An open end wrench is effective for tightening or loosening hex nuts, but it may not fit all fittings due to its fixed jaw size.

The correct answer encompasses the reality that multiple tools may be needed for the job. Each tool offers unique advantages depending on the specific situation and type of plumbing fixture being addressed. This variety is essential, as it ensures that the plumber can tackle any challenges that arise during the disassembly process efficiently. Thus, having all these tools available allows for a more adaptable approach to dealing with old plumbing fixtures.
