Plumbing can be an intimidating task for many homeowners. However, having the right tools for the job can make even complex plumbing projects much more manageable. One tool that every home plumber should have in their toolbox is a basin wrench. This versatile tool lets you quickly tighten and loosen nuts and bolts in tight spaces under sinks and behind toilets. With some practice and know-how, a basin wrench can help you become a master plumber quickly.
What is a Basin Wrench?
A basin wrench, sometimes called a faucet wrench, is a long, slender tool designed specifically for working in a confined area under a sink basin or behind a toilet. The head of the wrench has movable jaws that can grip and turn nuts and bolts. The long handle provides the leverage and reach to access the often awkwardly placed plumbing hardware. Basin wrenches come in different sizes, with 6-inch, 10-inch, and 12-inch models familiar. A longer wrench will allow you to reach further back into tight spaces.
Why is a Basin Wrench Useful?
There are several reasons why a basin wrench is an indispensable tool for the DIY home plumber:
Reaches Tight Spaces
The extended, low-profile neck on a basin wrench allows it to easily maneuver into the cramped area below sinks and behind toilets. Standard wrenches often need to be more bulky to fit into and turn nuts and bolts in these locations.
Provides Needed Leverage
The extended handle on a basin wrench provides the leverage you need to loosen stubborn fasteners. Using a short wrench or pliers in a confined space under a sink is complex and can strip the nuts and bolts.
Grips Many Fastener Shapes/Sizes
The adjustable jaw on a basin wrench can grip and turn various fastener shapes and sizes. A basin wrench can handle everything from hex nuts and bolts to slotted and Phillips head screws.
Protects Plumbing Fixtures
Unlike pliers and pipe wrenches, a basin wrench is less likely to damage existing plumbing hardware when turning fasteners. The smooth jaws securely grip without marring surfaces.
Common Basin Wrench Uses
Now that you understand what a basin wrench is and why it’s useful let’s look at some of the most common applications for this tool:
Installing or replacing kitchen and bathroom faucets is one of the most common uses for a basin wrench. It allows you to access and turn the nuts, securing the faucet onto the sink.
P-traps are the u-shaped pipes under sinks that hold water to prevent sewer gas from entering. A basin wrench lets you easily loosen and tighten the nuts to remove and install these traps.
Accessing Toilet Supply Valves
The valves connecting the toilet to the water supply line are tucked behind the toilet bowl. A basin wrench is the tool for turning these valves on and off.
Tightening Shower and tub Faucet Nuts
The faucet nuts for securing showerheads, tub spouts, and tub/shower valves are often in inconvenient spots. A basin wrench can reach these nuts with ease.
Removing Toilet Seats and Tanks
Taking off toilet seats and lifting the toilet tank requires accessing nuts beneath the bowl. A basin wrench is designed to work efficiently in this cramped space.
How to Use a Basin Wrench
Select the Correct Jaw Size
Basin wrench jaws typically have two size settings – one for smaller nuts and one for larger. Adjust the jaws to the approximate size of the nut/bolt you are turning.
Position the Jaws Properly
Make sure you place the jaws directly over and grip the sides of the nut or fastener before you attempt to turn. This prevents stripping.
Turn Slowly and Carefully
The long handle provides good leverage, so turn slowly and smoothly. Don’t force it if it won’t bend easily.
Change Handle Angle as Needed
You may need to swivel the handle to different angles to create the best leverage point for turning in tight spaces.
Use Penetrating Oil if Necessary
For stubborn, stuck nuts and bolts, apply penetrating oil and let it soak in before attempting to turn with the wrench.
Helpful Basin Wrench Techniques and Tips
Regular use will improve your skills with a basin wrench over time. Here are some helpful techniques and tips to further master using this invaluable tool:
- Try not to overtighten nuts – tighten just until snug
- Wrap the jaws with tape to prevent marring chrome or brass fittings
- Extend your reach by attaching a short piece of pipe over the handle
- Angle the handle slightly off perpendicular to create better turning leverage
- Use quick back-and-forth movements to break free stuck fasteners
- For extra reach, attach a short extension bar to the handle
- Keep the tool oiled and clean for smooth operation
- Replace worn-out or damaged jaws when they lose grip
Investing in Quality Basin Wrenches
As with any tool, buying high-quality basin wrench from reputable brands is worth the extra investment. Quality wrenches will feature smooth-turning actions, sturdy construction, and long-lasting jaws. Mastering the art of using a basin wrench takes some practice, but it is a skill that will serve you well for years. With the help of this versatile tool, you can confidently take on faucet repairs, toilet replacement, and many other plumbing projects. Equipped with the techniques and know-how covered here, you can handle any cramped plumbing space a basin wrench can fit into.
