Step 2 · Disconnect Water Supply Lines
Working through the access panel, position a bucket underneath the faucet connections to catch any trapped water. Using a basin wrench or an adjustable wrench, carefully loosen the nuts connecting the hot and cold flexible supply lines to the faucet handle tailpieces. The basin wrench is specially designed for reaching these tight spots. Turn the nuts counter-clockwise to loosen. Once loose, you can usually unscrew them by hand. Be prepared for a small amount of water to drain into the bucket.
