How To Install a Center-Set Faucet

 

Installing a center-set faucet

 

 

One of the most common types of bath faucets is a center-set faucet. These are available in a wide selection styles and prices, and are generally easy to install. The steps below describe how to properly install most common center-set bath faucets.

 

Measure the distance between the tailpieces of the faucet that you are replacing. Faucets are 4 inches on center up to 12 inches on center, so be sure to purchase the faucet that will fit your opening.

 

A WaterSense-certified faucet will help reduce water use.

 

Refer to the manufacturer’s instructions for the list of components, proper assembly, and maintenance of your new faucet.

 

 

Preparation

 

• If you have cultured marble or other composite sinks, it is recommended that you use silicone caulk as 
  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. 

 

Safety

 

• 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.

 

Savings

 

• 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.

MATERIALS:


Step 1: Turn off the water

Turn off the water

Remove 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

Be 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 around the lavatory openings with plumber's putty or silicone caulk

Place faucet gasket Assemble the faucet following the manufacturer’s instructions. Place the faucet gasket over the tailpieces so that it is between the sink and the base of the faucet.
  

Step 5: Set the faucet

Set the faucet The valves should fit into the hole spacing in the sink. Insert the faucet so that the base is parallel to the back of the sink and press the faucet down firmly.
  

Step 6: Hand-tighten the basin nuts

Hand-tighten the basin nuts Thread each, alternating from one nut to the other to draw the faucet body evenly over the gasket. Do not tighten all the way.
  

Step 7: Center the faucet body

Center the faucet body Measure or visually center the faucet body on the lavatory.
 

Step 8: Hand-tighten the basin nuts until they are snug

Step 9: Connect the water supply lines and check for leaks

Connect the water supply lines and check for leaks

Attach the supply lines to the faucet and angle valves. Wipe away any excess putty from around the faucet base.

 

Turn the water back on at the angle valves. Turn on the faucet and allow both hot and cold water to run for one minute. Check for leaks.
