Buy this cool tool, a special faucet nut wrench, to simplify faucet removal under those hard-to-reach sinks. It works quickly and easily and you avoid backaches.
Slide the open end of the wrench over the supply tube and push it up to the faucet nuts. Then turn the ratchet and it will self-center on the nut. Remove and reattach the ratchet handle as you rotate the nut.
The slots in the wrench catch the nut flanges as you turn the wrench with a ratchet from below.
Replacing a faucet is easy once you get the retaining nuts off. But that’s easier said than done. If you’re like most DIY plumbers, you probably use a cheap basin wrench. That means you have to crawl on your back all the way into the sink base. Then you have to arch your back, reach all the way up to the sink deck (while holding a flashlight in your mouth) and hook the jaw onto the faucet nuts.
Forget that. Just buy a Basin Buddy wrench (about $26) and snap it onto a long, 3/8-in. extension from your socket set. (One online source is simplyplumbing.com.) Then twist the ratchet handle as shown to loosen the nuts. You’ll save your back and do the job in a fraction of the time.
