  • Adjustable Wrench or Pliers

Step-by-Step Installation Process

  1. Turn Off the Water Supply: Locate the shut-off valves under your sink (usually labeled hot and cold). Turn them clockwise until they stop. Open the faucet to release any remaining water.
  2. Remove the Old Faucet:
    • Disconnect the water supply lines using an adjustable wrench or pliers. Place a bucket under the connections to catch any drips.
    • Use the basin wrench to loosen and remove the mounting nuts that hold the faucet in place.
    • Lift the old faucet out of the sink.
  3. Clean the Sink: Remove any old putty, caulk, or debris from around the faucet holes. A clean surface ensures a proper seal for your new faucet.
  4. Install the New Faucet:
    • Follow the manufacturer’s instructions carefully, as each faucet may have slight variations.
    • Apply plumber’s putty around the base of the new faucet where it will meet the sink.
    • Insert the faucet through the sink holes. From underneath, tighten the mounting nuts with the basin wrench. Be careful not to overtighten.
  5. Connect the Water Supply Lines:
    • Wrap Teflon tape around the threaded ends of the faucet’s supply line connections.
    • Attach the supply lines to the corresponding hot and cold water shut-off valves. Hand-tighten, then use an adjustable wrench to snug them slightly more (don’t overtighten).
  6. Reconnect the Drain:
    • If you’re replacing the drain assembly, follow the included instructions.
    • If reusing the existing drain, clean it thoroughly and apply plumber’s putty to the underside of the flange before reinserting it into the sink.
  7. Turn On the Water and Check for Leaks:
    • Slowly turn on the water supply valves.
    • Check for leaks around the faucet base, supply line connections, and under the sink. Tighten connections if needed, but avoid overtightening.
