Step 6 · Mount the New Faucet
Unpack your new faucet and identify all the parts. If your sink has three holes and the faucet only requires one, first place the gasket and then the escutcheon (deck plate) over the holes. Following the manufacturer's directions, carefully feed the faucet's water lines and threaded shank through the center hole. From underneath, slide the rubber gasket, followed by the metal washer and mounting nuts, onto the faucet's shank. Hand-tighten the nuts to secure the faucet. Check the faucet's alignment from above before giving the nuts a final tightening with the basin wrench or supplied tool until snug.
