Toolipedia: Adjustable Basin Wrench
Toolipedia: Everything you wanted to know about telescoping basin wrenches
What is an adjustable basin wrench?
An adjustable basin wrench is the perfect tool for hooking up and removing supply lines from the bottom of faucets. Because the threaded pipe of the faucet is blocked by the sink basin, reaching the pipe and working with the supply lines and the mounting nut can be challenging. The basin wrench is able to reach up to the supply line nut and retainer nut for the faucet and, because of its features, slip onto the nut and either loosen or tighten them.
Here are the basic parts:
- Telescoping shaft
- Pivoting fixed jaw
- Pivot pin
- Spring loaded curved jaw
The basin wrench is a useful tool for residential plumbers, remodeling contractors and DIYers.
How is a basin wrench used?
- Adjust the telescoping shaft to allow for room to turn the T-handle
- Slide the jaw of the wrench over the nut. Because it is spring loaded and curved, it should lock onto the nut.
- To loosen a nut, have the jaw opening on the right and turn counter-clockwise (Remember, you will be looking up at the nut.)
- To tighten, do the reverse: jaw to the left, and turn clockwise.
- Be sure to turn off the water supply at the valve below the working area
- Open the faucet valve to relieve any extra pressure
- Wear safety glasses to prevent any dust, corrosion or other foreign objects from falling into your eyes as you work
What are the different types of basin wrenches?
- Some do not have a telescoping shaft
- Some have lights included to help see the nuts better
- Some, especially older models, do not have a spring loaded curved jaw
What makes a good basin wrench?
- Telescoping shaft
- Strong spring in curved jaw
- Long, thick T-handle
- Minimal play in the pivot head
Basin Wrench Tip: Getting a bit more torque
Sometimes supply line nuts and retainer nuts can be stuck on due to corrosion. Using the hole on the end of a crescent wrench or a small pipe to extend the length of the T-handle will give you more torque.
