How To Install a Widespread Faucet




• If you have cultured marble or other composite sinks, it is recommended that you use silicone caulk;
plumber’s putty may discolor the sink.
• Allow additional time to remove old faucets, fittings or pipes as corrosion and inaccessibility can make
removal difficult.



• Turn off the water supply to help prevent water from escaping during the installation.
• If you have to work upside down under the sink, be sure to wear safety glasses to protect your eyes from
falling debris as you install your new faucet.




• Installing the faucet yourself is a great way to save on the cost of your project.
• Consider a low-flow faucet to save water and money on utility bills.
• If your old faucet is still in good working order, consider donating it to a local charitable organization, or
recycle any metal parts rather than just throwing them out with the trash.

Step 1: Turn off the water

turn off the main water supplyRemove all items from under the sink. Place a bucket, pan or rags under the work area. Use heavy towels to support your body if you are reaching into the sink area and under or through the vanity.
Turn off the hot and cold water supply lines at the shut-off valves beneath the sink. If there are no shut-off valves, turn off the main water supply. This is a good time to install stop valves as part of this project so you can turn off the water easily in the future.Turn the faucet on to release the pressure in the water lines.

Step 2: Remove the old faucet

Remove the old supply lines to remove the faucetBe sure to wear safety glasses to protect your eyes from falling debris as you work upside down under the sink.Remove the old supply lines and the mounting nuts to remove the faucet. Apply a penetrating lubricant if the lines or nuts are corroded or in a hard-to-reach position. Do not use strong force to remove them – be gentle yet persistent.
Lift the faucet fixture from the top of the sink. A putty knife can remove all of the old sealant from the top. Use a cleaner suitable for your sink type to clean the area.

Step 3: Seal the spout base

 Seal the base of the spoutForm plumber’s putty into a rope and place it on the base of the spout. Press the putty against the base. Set the spout into place.

Step 4: Hand-tighten the basin nut

Tighten the nut just to hold it in placeTighten the nut just enough to hold it in place. Do not overtighten the nut because you will need to first center the spout on the sink.

Step 5: Thread the tee on the spout

Center the tee to line up with the faucetsCenter the tee so the outlets are approximately parallel to the back wall and line up with the faucets on either side.

Step 6: Center the spout

Tighten the spout using a basin wrenchOnce it is centered, tighten the spout from beneath the sink using a basin wrench.

Step 7: Place the faucet valves in the sink

Slide the washer beneath the sinkSlide the washer over the threads from beneath the sink. Tighten the valve nut until snug.

Step 8: Connect the faucet valve lines to the faucet valve

Apply pipe compound or Teflon tape to the threads of the valve lineApply pipe compound or Teflon tape to the threads of the valve line. Connect to the faucet valve, and hand-tighten. Apply pipe compound or Teflon tape to the other end of the valve line and hand-tighten onto the spout tee.

Step 9: Finish the assembly and tighten the connections

Assemble water supplies and tighten the connectionsApply pipe compound or Teflon tape to the threads of the water supply tailpieces and connect the hot and cold water supplies to the hot and cold supply valves. When the entire assembly is complete, go back and tighten all the connections with an adjustable wrench.
The last step is to connect the faucet handles to the valves. Align the handles to the “off” position. Apply a bead of plumber’s putty to the faucet handle base, attach the handle, center it, and tighten the faucet nut below the sink with a basin wrench.

Step 10: Connect the water supply lines and check for leaks

Turn the water back on at the shut-off valvesTurn the water back on at the shut-off valves. Turn on the faucet and allow both hot and cold water to run for one minute. Check for leaks.
Install the matching pop-up drain (if supplied) with your new faucet.
