Install a High Efficiency Faucet

Tired of paying those high water bills?

This simple project will teach you how to install a high efficiency faucet that will reduce the amount of water used in the sink by up to 30%. Standard faucets use 2.2 gallons of water per minute (GPM), whereas high efficiency faucets can use as little as 1.5 GPM without affecting performance.

1  Before you start


  • Clean out cabinet and inspect the area where you will be working.
  • Block the drain opening with a cloth.
  • Have a bucket on hand to catch any water.
  • Position towels so the edge of the cabinet doesn't dig into your back as you work.
  • Some faucets come with lifetime warranties on parts. Check with the manufacturer for details.
  • If you have an electrical outlet beneath your sink, turn off power to it before you remove the old faucet and restore power to it only after the new faucet has been tested for leaks.
  • Use a basin wrench to reach into tight spaces behind your sink to avoid hand injuries.

2  Turn Off Water


Turn off the water at the shut off valves under the sink or at the main water supply.


3  Connect Supply Lines to Faucet


Connect the supply lines to the faucet tailpieces. Tighten the coupling nuts with slip-joint pliers or a basin wrench.


4  Apply Sealant & Position Faucet


Apply a quarter-inch bead of plumber's putty around the base of the faucet. If your sink is made of cultured marble, use silicone caulk.
Insert the faucet tailpieces with supply lines into the holes in the sink.
Position the faucet base parallel to the back of the sink and press the faucet down.


5  Screw on Mounting Nuts


From beneath the sink, screw the friction washers and mounting nuts onto the faucet tailpieces and tighten them with slip-joint pliers or a basin wrench. Wipe away any excess putty around the faucet base.


6  Connect Supply Lines to Shut off Valves


Attach the faucet's supply lines to the shut off valves and tighten the nuts. Give the nuts an extra quarter- turn with an adjustable wrench while holding the valve with another wrench.
