Step 5 · Mount New Faucet Components
Unpack your new faucet kit and review the manufacturer's instructions. Some kits require a bead of plumber's putty around the base of the faucet bodies and spout, while others use pre-installed rubber gaskets. Follow the instructions for your specific model. Position the new spout and handle valves through the holes on the tub deck. From underneath, slide on any supplied rubber or metal washers and then thread on the mounting nuts by hand until they are snug. Use your basin wrench to give each nut a final quarter to half-turn to secure it firmly. Do not overtighten, as this can crack the tub or the plastic nuts.
