How to use a Basin Wrench

A basin wrench is a specialty plumbing tool that nearly all professional plumbers have on hand and one that every homeowner who performs DIY plumbing work should also have on hand. Although it performs a single job well, installing or removing a faucet, it is the only tool that can perform that one job well. Following a brief learning period, the homeowner will be able to complete a faucet removal or installation that is perfect every time. No more re-assembling and disassembling the tap or at least with far less effort. It will quickly become a vital component of your plumbing equipment collection.

Installation of kitchen and bathroom sink faucets is usually accomplished through the use of low-profile mounting nuts that can only be accessed from beneath the sink, behind the sink’s basin. So it’s helpful to have some tools for getting under there.

What Is the Function of a Basin Wrench?

An adjustable basin wrench is a specialized plumbing instrument that has a long handle and a revolving, self-adjusting gripping head. These nuts are tightened and removed using this tool. Because of the tool’s design, it is able to be used in places where other tools cannot.

Using The Telescopic Basin Wrench

If you are removing a faucet or a water supply line from a kitchen or bathroom sink, you will most likely need to use a basin wrench to loosen the bolts on the faucet or water supply line. Basin wrenches are available in a variety of shapes and sizes; nevertheless, the basic notion of how to use a basin wrench is the same regardless of the form.

The Telescoping Basin Wrench is our top pick for the best overall basin wrench on the market today. The long-lasting tool is made of steel and has an extensive range of 11 to 16 inches, allowing for greater versatility. In addition, the ratcheting head pivots in both directions so that you can use it to tighten or loosen nuts, and the jaws are spring-loaded so that they hold their position tightly and steadily. It’s small and lightweight, weighing only 1.66 pounds, yet it works on nuts ranging in size from 1 to 2 inches in diameter.

A quick Review of Telescopic Basin Wrench

A few dollars will get you a telescopic basin wrench. It’s impossible to tell what’s at the bottom of the basin, which is something that happens frequently. To tighten or repair a loose faucet, reach under the sink with this telescopic wrench. Turning it left or right closes or opens the tap. The head is gripping the faucet nut when you turn it to the right and you can undo that by just rotating the head over.

Telescopic Basin wrench adjustable shaft

This one’s square shaft length may be adjustable. Turn it with the handle or a square shaft adjustable wrench. The swivel end of the wrench allows you to tighten or loosen the nut from various angles. While turning the wrench’s end is difficult, it is needed to keep it from moving. The spring-loaded jaws can unscrew a nut.

Using the jaws in this position, insert the wrench into the nut; and position it so that the round serrated part of the wrench is on one of the ends of the nut and the flat serrated end is on the flat side of the nut. Then crank the nut counterclockwise until the nut is loose. It is possible to attempt turning the nut while holding the wrench in one half and curling it around the nut.

So long as you can reach up and tighten the nut. You can lift it to around 400 mm, the height of the basin tap. You are capable of turning it from the bottom. By rotating the small bar counterclockwise, and quickly unscrew and tighten the cap. There’s no reason for you to shred my knuckles with a regular spanner while reaching up to tap your hand.

However, this is unlikely to work in practice because the nut will not come loose with a wrench. To tighten a sink, you may have to remove it from the vanity or counter and hacksaw it off; Alternatively, you can use a Dremel tool with a cutting wheel.


As a caution, however. Most of the new tightening nuts are plastic. It’s important not to over-tighten them with a wrench. If you over tighten them, you risk breaking the plastic nut, which may be very expensive to repair.

How the telescopic basin wrench works

Basin wrenches are equipped with “teeth.” One has a swiveling jaw and a spring in the middle. The spring keeps the wrench in its regular position by holding it closed. Another set of teeth can be found on the interior of the head, this time on a section of the wrench head that is permanently attached. Due to the pivoting nature of the wrench head, you may rotate the complete head assembly 180 degrees. When you’re in the right position to reach the faucet nut, you’ll extend the wrench head up, into the flat position, to reach it.

It is a complete and utter success. With that faucet on there tighter than you ever imagined, you’ll be able to get it in less than five minutes. If you have the right equipment, you can accomplish your work very quickly.

Once you begin to twist the nut, the “Jaw” will flip open around the nut. Alternatively, you can reach up and open it with your finger until it has settled around the nut and bolt. In order to tighten the nut, you must twist the “T” handle that comes with the wrench, which is in the vertical position when you do so. By using the proper route, you can tighten it. Alternatively, reverse the head and rotate the nut in the opposite direction to loosen it. It’s straightforward and uncomplicated.


The teeth rip the nut. The teeth sink in when pressure is applied, but there isn’t much damage. Even tho it’s not a big deal, you’d need to replace the nut if you did this too many times.

We would strongly recommend this item to anyone who has deep sinks and hard-to-reach hardware inside the sink cavities. It is quite useful.

My personal experience

I simply had to replace the kitchen faucets on our main floor because the old ones were leaking and not worth repairing. Everything went nicely except for the problem that I couldn’t lock the mounting nuts sufficiently to prevent the faucet from slipping.

Since no local hardware stores carried basin wrenches, I resorted to Amazon, where I found them in-stock and competitively priced. I liked this wrench because it was extendable. It worked, and it completed the task at hand.

The only problem is that the wrench only just barely fit and grabbed a common plastic Delta Faucet nut. Preventing me from being able to turn it. In order for the fins on the plastic nut to just barely catch in the first ridge of the jaw. I had to make sure they were just barely captured. It made me wish that I had got the large opening jaw version when I originally acquired it. I’m not even sure if there was enough room under the sink for the larger jaw version. True, the wrench fits the water connection pipes, but so does my crescent wrench.

Furthermore, the jaw on the model I purchased was so thick that there was hardly enough space between the cabinet wall and the sink to turn the nut even halfway.

Final Result

Overall, I completed the task and ensured that the faucet was securely installed. This tool assisted me in completing the task. However, it was not completely satisfactory for my application requirements. When I had to modify the wrench handle to get sufficient clearance beneath the cabinet. While I was turning the handle of the wrench, it didn’t interfere with drain pipes or the garbage disposal. The extensible handle came in handy.

This is one of those unusual tools that makes it easier to operate in a confined space and complete the task at hand. This is one of those tools that you don’t use all that often, but when you do, you’ll be glad you have it!

It aided me in completing the task and saved me money by avoiding the need to engage a professional plumber.
