Assuming that you won’t be working on pipes that are in tight spaces or with lots of surrounding obstructions, a straight pipe wrench should be ideal for most of your home plumbing projects. Look for options that are between 14 to 18 inches long with jaws that can accommodate pipes that are up to 2.5 inches in diameter. But also look for pipe wrenches that are adjustable so that you don’t find yourself running to the hardware store for every project because of varying pipe sizes.
