How do I get my hands behind the sink?
So the answer is you can't unless you have tiny dinosaur hands. There is a great tool called a basin wrench. It has a little extension arm so you can get up there and loosen the nut that is holding the faucet in place. Once it is loose, you are good to go.
Pro Tip - grab a screw and a nut to make sure you are turning the nut the correct way. If you crank it on to tight things can get pretty interesting.
If this sounds like to much work, give us a call and we can swap out the faucets for you. Have a great day!
